Even simple movements require the integration of information from multiple areas of the brain. This process breaks down when brain damage occurs, resulting in neurological disorders.

But what if researchers could find a way to bypass those damaged areas and maintain the flow of information?

Kevin Mazurek, a postdoctoral fellow in the lab of Marc Schieber, professor of neurology, described how the lab is making progress in doing just that. He finished in first place and took the audience prize as well in the Meliora Weekend competition for the Steadman Family Postdoctoral Associate Prize in Interdisciplinary Research.

Mazurek’s prizes were worth $1,250.

Using micro electrical stimulation in primates, “we’ve shown that we can deliver the information successfully to two functionally different areas of the brain,” Mazurek explained. “This is an important first step.”

The next steps in the research, which incorporates neurology, neuroscience, electrical engineering, and biomedical engineering, include expanding the ability to communicate information across a wide reach of brain areas. This could “potentially improve the quality of living for individuals with injuries such as stroke, traumatic brain injury, or Alzheimer’s disease.”

This is the second year of the competition.

It is open to all postdoctoral scholars and appointees in the School of Medicine and Dentistry, and in Arts, Sciences & Engineering. Four prizes are awarded for research that exemplifies the importance of cross- disciplinary approaches toward examining high impact questions of science. Prizes were awarded based on 3-minute oral presentations to a panel of judges.

This year’s topics ranged from “Recent Breakthroughs in Understanding the Brain’s Waste Removal System” to “Catalytic Solar-Driven Generation of H2 in Artificial Photosynthesis” – and the benefits of yoga in helping cancer patients cope with the side affects of chemotherapy.

Can a workout regimen for your mind and body help to fend off Alzheimer’s disease?

Physical and mental activity have been shown to boost brain function in different ways, but a new study will look to see if the benefits of engaging in a rigorously designed program that includes both aerobic exercise and brain training will complement each other, producing greater gains in cognition than if both activities had been done independently.

Feng Vankee Lin, Ph.D., R.N., assistant professor in the University of Rochester School of Nursing, the Departments of Neuroscience, Brain and Cognitive Sciences, Neurology, and Psychiatry, and director of the Cog-T Laboratory promoting successful aging, and Fang Yu, Ph.D., R.N., G.N.P.-B.C., F.G.S.A., F.A.A.N., associate professor at the University of Minnesota School of Nursing, are principal investigators on the five-year, $3.67 million grant from the National Institute of Aging.

“This is the first trial to test the synergistic effects of a combined program of aerobic exercise and cognitive training on cognition and mechanisms relevant to Alzheimer’s disease-associated neurodegeneration in older adults with mild cognitive impairment,” said Lin.

URMC Drug to be Tested for Delirium and Dementia Following Surgery; Also Brain Disorder ALS

A picture of an older woman and her daughter in the background

For those caring for elderly parents or grandparents, this scene may be familiar: Grandma falls and fractures her hip. Grandma has surgery to repair the broken hip. Grandma comes out of surgery delirious and confused; she can’t remember simple things, or focus on more than one thing at a time.

More than half of older adults suffer from delirium after surgery that may progress to dementia, a condition called postoperative cognitive dysfunction (POCD). There are no good treatments for postoperative cognitive dysfunction, which is associated with increased illness and death. Estimates suggest that caring for patients with POCD costs more than $150 billion a year.

A team of researchers from the University of Rochester Medical Center (URMC) and Duke University Medical Center is addressing the problem, with the help of a five-year, $2.8 million grant from the National Institutes of Aging at the National Institutes of Health.

What causes postoperative cognitive dysfunction?

What causes postoperative cognitive dysfunction is not entirely understood, but the body’s immune response to surgery and subsequent inflammation throughout the body – including in the brain – likely play a role. The team, led by Niccolo Terrando, Ph.D. at Duke, will test in animal models a drug developed in the laboratory of Harris A. “Handy” Gelbard, M.D., Ph.D. at URMC. Called URMC-099, the drug tamps down the body’s immune response and reduces inflammation.

Study Pokes Holes in Fetal Alcohol Hypothesis

Wednesday, October 4, 2017

fetal alcohol syndrome

A new study published in the journal Brain Behavior and Immunity appears to challenge the theory that cells in the brain’s immune system are the culprit behind the neurological damage that occurs in children exposed to alcohol while in the womb.

“In order to develop treatments for this condition, we must first understand how alcohol affects the developing brain,” said Ania Majewska, Ph.D., an associate professor in the Department of Neuroscience at the University of Rochester Medical Center (URMC) and lead author of the study. “While the hypothesis that dysfunctional immune cells play a role in fetal alcohol syndrome is logical and enticing, it appears that this idea may be a scientific dead end.”

Exposure to alcohol in the womb can lead to fetal alcohol spectrum disorders (FASD), a condition that causes lifelong physical and cognitive impairments, and for which there is no available treatment. The symptoms suffered by individuals with FASD can range from poor impulse control and attention, learning disabilities, compromised fine motor skills, and delays in the ability of the brain to process visual and auditory information. FASD is diagnosed in about one out of every 100 babies born in the U.S.

URMC Joins Landmark Brain Development Study

Tuesday, September 26, 2017

Child in an MRI scanner

The University of Rochester Medical Center (URMC) is participating in what is being characterized as the largest long-term study of brain development and child health. The study will follow the biological and behavioral development of more than 10,000 children from ages 9-10 through early adulthood.

The Adolescent Brain Cognitive Development (ABCD) Study was created by the National Institutes of Health to evaluate the developmental period during which the brain undergoes dramatic changes. The study will seek to better understand how children’s experiences impact brain maturation and other aspects of their lives, including academic achievement, social development, behavior, and overall health.

“Adolescence is a time of extraordinary physical, emotional, and intellectual growth,” said John Foxe, Ph.D., director of the Del Monte Neuroscience Institute and principal investigator of the URMC ABCD Study. “Yet there is a great deal that we don’t know about how experiences such as participation in sports or music programs, screen time, sleep patterns, and long-term exposure to medications and stimulants impact their transition to adulthood.”

The Microglial Fractalkine Receptor is not Required for Activity-Dependent Plasticity in the Mouse Visual System

Microglia have recently been implicated as key regulators of activity-dependent plasticity, where they contribute to the removal of inappropriate or excess synapses. However, the molecular mechanisms that mediate this microglial function are still not well understood. Although multiple studies have implicated fractalkine signaling as a mediator of microglia–neuron communications during synaptic plasticity, it is unclear whether this is a universal signaling mechanism or whether its role is limited to specific brain regions and stages of the lifespan. Here, we examined whether fractalkine signaling mediates microglial contributions to activity-dependent plasticity in the developing and adolescent visual system. Using genetic ablation of fractalkine's cognate receptor, CX3CR1, and both ex vivo characterization and in vivo imaging in mice, we examined whether fractalkine signaling is required for microglial dynamics and modulation of synapses, as well as activity-dependent plasticity in the visual system. We did not find a role for fractalkine signaling in mediating microglial properties during visual plasticity. Ablation of CX3CR1 had no effect on microglial density, distribution, morphology, or motility, in either adolescent or young adult mice across brain regions that include the visual cortex. Ablation of CX3CR1 also had no effect on baseline synaptic turnover or contact dynamics between microglia and neurons. Finally, we found that fractalkine signaling is not required for either early or late forms of activity-dependent visual system plasticity. These findings suggest that fractalkine is not a universal regulator of synaptic plasticity, but rather has heterogeneous roles in specific brain regions and life stages.

Ross Maddox Finds Auditory Brainstem Responses to Continuous Natural Speech in Human Listeners

Friday, September 22, 2017

Ross Maddox

Ross Maddox, PhD

Ross Maddox's lab has posted the preprint for his latest paper on biorXiv! They showed that it's possible to measure the response of the auditory brainstem to natural speech using EEG.

Speech is an ecologically essential signal whose processing begins in the subcortical nuclei of the auditory brainstem, but there are few experimental options for studying these early responses under natural conditions. While encoding of continuous natural speech has been successfully probed in the cortex with neurophysiological tools such as electro- and magnetoencephalography, the rapidity of subcortical response components combined with unfavorable signal to noise ratios has prevented application of those methods to the brainstem. Instead, experiments have used thousands of repetitions of simple stimuli such as clicks, tonebursts, or brief spoken syllables, with deviations from those paradigms leading to ambiguity in the neural origins of measured responses. In this study we developed and tested a new way to measure the auditory brainstem response to ongoing, naturally uttered speech. We found a high degree of morphological similarity between the speech-evoked auditory brainstem responses (ABR) and the standard click-evoked ABR, notably a preserved wave V, the most prominent voltage peak in the standard click-evoked ABR. Because this method yields distinct peaks at latencies too short to originate from the cortex, the responses measured can be unambiguously determined to be subcortical in origin. The use of naturally uttered speech to evoke the ABR allows the design of engaging behavioral tasks, facilitating new investigations of the effects of cognitive processes like language processing and attention on brainstem processing.

Quadcast: Rebooting the Brain for Better Vision After a Stroke

Thursday, September 14, 2017

Maybe you’ve recently suffered a stroke and are now starting therapy, trying to regain speech, motor functions, and possibly improve memory. But your vision is damaged, too, and there’s no therapy available.
Yet.
Krystel Huxlin, director of research and the James V. Aquavella Professor of Ophthalmology at the University of Rochester Medical Center’s Flaum Eye Institute, has been working in her lab over the last ten years to change that. Here’s how she sums up her latest results, published earlier this year in the journal Neurology:

“If people do exactly what we tell them and they don’t cheat, the success rate has been in our hands a 100 percent.”

Huxlin spoke at the inaugural Light & Sound Interactive conference in Rochester, jointly sponsored by the University of Rochester and the Rochester Institute of Technology, as part of a panel on blindness and visual impairment that addressed corrective, restorative and rehabilitative approaches.

Study Uncovers Potential Tool, Based on Rapid Eye Movements, for Detecting Autism Earlier

Tuesday, August 15, 2017

“Researchers have long fixed their attention on eye-tracking in detecting autism spectrum disorders, but now they may have discovered a new tool that could lead to earlier diagnosis and intervention.” the research is by John Foxe, the Kilian J. and Caroline F. Schmitt Professor in Neuroscience and chair of the Department of Neuroscience.

In a July 12 article in the European Journal of Neuroscience, researchers at the University of Rochester linked differences in the cerebellar vermis (in the rear of the cerebellum, which controls the development of human movement, social skills and emotional development) to the plasticity of saccadic or rapid eye movements within a subgroup of people with disorders on the autism spectrum (ASD).

Rapid eye movements (also known as saccade) may be the key, say Edward G. Freeman, Ph.D., and John J. Foxe Ph.D. These eye movements-typically quick, precise and accurate in healthy eyes-occur when we shift our gaze between objects and are important in interacting with the world. Sometimes though, in people with ASD, the movements can "over- or undershoot the intended target locations," they wrote in the study.

Scientists Inject Ferrets' Brains With Rabies to Study ... Vision?

Friday, July 28, 2017

Photo of a ferret

Newly appointed Dept. of Neuroscience faculty member, Farran Briggs, Ph.D. has her research highlighted on Wired.

When ferrets get a rabies shot in a neurobiology lab, they don't get infected with the virus—or even inoculated against it. They get a brain hack that might just explain how your brain handles vision, and maybe even your other senses, too.

In a lab at Dartmouth, scientists are experimenting with targeted injections of a modified rabies virus into the brains of ferrets—essentially allowing them to control how the animal responds to simple visual patterns. The goal is to understand the brain's enormously complex visual processing system. But really? Rabies? Ferrets? Are these guys just screwing around?

Lots of visual research depends on lab mice—the most popular of model organisms in biology. But Dartmouth neuroscientist and lead author Farran Briggs wanted to study an animal that uses its vision the same way humans do, in an evolutionary sense: to prey on tasty snacks. Mice aren’t predators, and their vision falls solidly in the ‘legally blind’ range. So these vision researchers turned to the notoriously vicious ferret and its front-facing eyes. They're color blind, but at the neural level, ferrets’ visual systems have “remarkable similarities to a primate, and a human,” says Briggs. (Ferrets also help avoid the ethical issues of experimenting on primates.)

Eye Test Could Help Diagnose Autism

Monday, July 24, 2017

Close-up photo of human eye

A new study out in European Journal of Neuroscience could herald a new tool that helps physicians identify a sub-group of people with Autism spectrum disorders (ASD). The test, which consists of measuring rapid eye movements, may indicate deficits in an area of the brain that plays an important role in emotional and social development.

“These findings build upon a growing field of research that show that eye movement could serve as a window into a part of the brain that plays a role in a number of neurological and development disorders, such as Autism,” said John Foxe, Ph.D., director of the University of Rochester Medical Center Del Monte Neuroscience Institute and co-author of the study.

ASD is characterized by a wide range of symptoms that can vary in severity from person to person. This unpredictability not only presents a challenge for diagnosis, but also how best to devise a course of treatment. Identifying the specific phenotype of the disorder is, therefore, an essential first step to providing effective care.

NIH Grant to Examine ‘Person-Centered’ Approach to Cognitive Training

Thursday, July 20, 2017

Photo of Feng Vankee LinThe National Institutes of Health has awarded a grant to URMC researchers exploring methods of making cognitive training more effective for older adults by improving their attitudes toward computers.

Feng Vankee Lin, Ph.D., RN, an SON assistant professor and director of the CogT Lab promoting successful aging, and Benjamin Chapman, Ph.D., MPH, associate professor of Psychiatry, are principal investigators on the $421,000, two-year study.

Computerized cognitive training methods, such as online “brain games” have been widely implemented among adults with mild cognitive impairment (MCI) in recent years. However those interventions have not proven to be a consistently reliable method of improving or maintaining the cognitive health of older adults. Results are highly variable, and one possible explanation lies in how comfortable seniors feel using technology.

Photo of Benjamin Chapman“The goal of this study is to generate a proof-of-concept for an intervention that may improve attitudes toward computers among those older adults with MCI,” said Lin, who is now principal or co-investigator on six current NIH grants. “Improving the intervention engagement of those individuals, we think, will then help us develop more effective computerized cognitive interventions in the future. It is the first study that we know of that strives to augment computerized cognitive training by addressing an attitudinal or affective element of the person.”

At the core of the study is the notion of person-centered care – integrating individuals’ preference throughout the process of intervention. The person-centered approached has been shown to improve engagement among older persons, including those with MCI, and pilot data collected at assisted-living facilities suggests that computer-led leisure activities promotes psychological well-being among older persons with MCI and may change their perception about technology. A computer used for fun activities may no longer seem daunting, complex, or irrelevant, but instead be seen as familiar and enjoyable.

“These results are consistent with a number of theories indicating that exposure to pleasurable experiences with an object or task improves several dimensions of attitudes, including affective and cognitive components, as well as behavior and motivation,” Lin said.

Grounded in this pilot data and the theory around it, investigators will lead a small randomized controlled trial among assisted-living residents to assess whether a period of computer-led leisure activities prior to cognitive training improves attitudes toward computers, engagement with the intervention, or cognitive outcomes.

Anton Porsteinsson, M.D., professor of Neurology, is a co-investigator on the grant, which is also receiving recruitment support from Dallas Nelson, M.D., and Sarah Howd, M.D., in the Department of Medicine’s Division of Geriatrics and Aging.

Hidden Herpes Virus May Play Key Role in MS, Other Brain Disorders

Monday, July 10, 2017

The ubiquitous human herpesvirus 6 (HHV-6) may play a critical role in impeding the brain’s ability to repair itself in diseases like multiple sclerosis. The findings, which appear in the journal Scientific Reports, may help explain the differences in severity in symptoms that many people with the disease experience.

“While latent HHV-6 – which can be found in cells throughout the brain – has been associated with demyelinating disorders like multiple sclerosis it has not been clear what role, if any, it plays in these diseases,” said Margot Mayer-Proschel, Ph.D., an associate professor at the University of Rochester Medical Center Department of Biomedical Genetics and co-author of the study. “These findings show that, while in the process of hiding from the immune system, the virus produces a protein that has the potential to impair the normal ability of cells in the brain to repair damaged myelin.”

Ed Freedman and John Foxe Publish in EJN

Friday, June 16, 2017

Photo of Dr. Ed Freedman

Ed Freedman and John Foxe have just published preliminary data from a study examining eye movement changes in individuals with Autism Spectrum Disorders (ASD), particularly looking at the role of the cerebellum (DOI: 10.1111/ejn.13625). The cerebellum, Latin for ‘little’ brain, sits at the base of brain, underneath the cerebral cortex. Although it has been called ‘mini’, the cerebellum actually has more neurons, or cells, than the cerebral cortex. Classically considered to play a role in the control of movements and the learning of motor patterns, it is now known to play a role in emotion and cognition through its connection to the rest of the brain. And, there is evidence that the structure of the cerebellum is altered in a sub-population of individuals with ASD.

Photo of Dr. John Foxe

In the current paper, Ed and John present the results of experiments tracking the rapid eye-movements made when looking from one object to another, or saccades, in individuals with ASD. Accuracy and precision are maintained by careful comparison of the movement command produced by the brain and the results of the actual movement. Any differences between these lead to adjustments of the commands for ensuing saccades. This type of sensorimotor adaptation is dependent on the proper functioning of the cerebellum. However, there is anatomical evidence that some people with an ASD have cerebella with slightly altered structure. If the cerebellar structure is altered, is its function also altered in this sub-group of people? Assessing the ability of people with an ASD to adapt saccade amplitudes is one way to determine whether this function of the cerebellum is altered in ASD.

Another point of interest is determining if the deficits in saccades relate to any of the other key symptoms observed in ASD.

If saccade adaptation deficits do turn out to be a consistent finding in a sub-group of children with ASD, this raises the possibility that saccade adaptation measures may have utility as an early-detection endophenotype. Changes in cerebellar structure most likely occur in utero and very recent work has shown that saccadic adaptation can be measured in children as young as 10-41 months of age is a most encouraging development indeed. - Ed and John

Featured in The Science Times: How Alzheimer's Catches People Skimping Sleep: New Study Explains Cause Of Dementia

Wednesday, May 24, 2017

Photo of Dr. Maiken Nedergaard

A recent scientific study shows that insufficient amount of sleep leads to the development of Alzheimer's disease. Researchers gain more evidence and are beginning to believe that lack and poor quality of sleep results to the fusion of Amyloids, proteins that bond together to form Alzheimer's plaques.

Dr. Maiken Nedergaard, the lead researcher from the University of Rochester Medical Center, explains the glymphatic system that is present in humans. She says that this system is 10 times more active when in slumber than when awake. The process allows cerebrospinal fluid to flow through spaces around the neurons of people's brains. This a method of purging unwanted proteins (Amyloids) and other wastes into the circulatory system garbage collectors and eventually flushes it out of the body.

In simple terms, Nedergaard explains that the brain has its own sanitation and public works department. It is like a network of sewer facilities mostly done during the brain's nightlife. An example of a housekeeping staff descending to building offices for a cleanup duty to avoid the lumping compound that causes Alzheimer's.

Keshov Sharma Presents Late-Breaking Data at Society for Biological Psychiatry in San Diego

Monday, May 22, 2017

Photo of Keshov Sharma in front of a scientific poster at a conference in San Diego

Keshov Sharma, a second-year student in the Medical Scientist Training Program (MSTP), presented work collected in part during his laboratory last summer at the SOBP Annual meeting in May. The study, “Dual Neural Connections between the Amygdala and the Ventromedial (BA25) and Dorsomedial (BA24) Prefrontal Cortex in the Macaque”, was inspired by recent data in rodents implicating separate subcircuits between amygdala and infralimbic cortex, and amygdala and the prelimbic cortex, in fear extinction and fear consolidation, respectively. To find a comparable bridge to human fear studies, we designed studies to examine this question in monkeys because of their relatively larger and more subdivided cortical architecture that parallels the human. Analyzing dual retrograde injections into proposed ‘homologues’ of these rodent cortical regions in monkeys, we found that cells projecting to these cortical regions were mostly intermixed in several specific amygdala subnuclei in primates. Moreover, a subpopulation of neurons projected to both prefrontal regions, indicating common neural modulation of these functionally dissociated areas. Thus, amygdala inputs to separable, functionally opposed cortical regions exist in close proximity to one another in specific parts of the amygdala, and some of these cells participate in both ‘subcircuits’. Understanding this organization may provide clues about how to ‘tip the balance’ between fear learning and fear extinction learning in higher species, including humans that suffer from illnesses characterized by aberrant fear learning.

Introducing the Center for NeuroTherapeutics Discovery

Tuesday, May 16, 2017

The Center for Neural Development and Disease, led by Harris A. (Handy) Gelbard, M.D., Ph.D., since 2008, will now be the Center for NeuroTherapeutics Discovery, reflecting an increased emphasis on translation and the creation of intellectual property that will lead to new therapies for nervous system disorders.

Gelbard, professor of Neurology, Pediatrics, Neuroscience and Microbiology & Immunology, will continue as director. His research, coupled with the work of Charles Thornton, M.D., professor of Neurology and Neuroscience, and Marc Halterman, M.D., Ph.D., associate professor of Neurology, Neuroscience and Pediatrics, will serve as the anchor of the new center. The trio has a strong track record of grants, publications, and patents, as well as academic and commercial relationships that they are actively pursuing to bring new treatments to the public.

“The Center for NeuroTherapeutics Discovery was developed out of the Center for Neural Development and Disease to create more visibility for academic and commercial partnerships as a necessary bridge for bringing new therapeutics forward,” said Gelbard. “This represents a way to do the best and most cutting edge science possible in a time when the traditional avenues towards funding academic research are changing rapidly.”

The center will bring together many investigators from across the Medical Center and River Campus to identify the mechanisms that lead to various neurological disorders, including HIV-associated neurocognitive disorder (Gelbard lab), myotonic dystrophy (Thornton lab) and stroke (Halterman lab). The center remains committed to its members that investigate the molecular signaling events that lead to nervous system disease during development and aging. Industry partnerships and resources will be sought to fast-track existing therapies or create new molecules that affect these disease mechanisms.

Treatments that harness the immune system to help regenerate damaged cells will be a major focus at the center; the team believes that this approach is broadly applicable to a range of acute and chronic neurodegenerative disorders, such as Parkinson’s disease, multiple sclerosis and Alzheimer’s disease.

University start-ups highlighted in national innovation report

Thursday, April 27, 2017

Two University of Rochester start-up companies are among those singled out in a new report from the Science Coalition. The report, “American-Made Innovation Sparking Economic Growth,” identifies 102 companies that trace their roots to federally-funded university research.
“The innovation that drives economic growth in the U.S. is based, in large part, on the scientific discoveries made in research universities and funded by the federal government,” said Rob Clark, University provost and senior vice president for research. “As a nation, it is imperative that we continue to support the fundamental science that leads to new technologies and improves lives.”
Clerio Vision was founded in 2014 by Wayne Knox and Jon Ellis with the Institute of Optics, and Krystel Huxlin with the Flaum Eye Institute in the Medical Center. The company is developing a new technology that improves eyesight by “writing” a prescription on the cornea using small pulses from a laser that change the focusing power of the eye. Because the technique doesn’t change the shape of the cornea like LASIK procedures, it can be repeated as needed over a person’s lifetime to correct vision. The research to develop the technology was funded in part with a $200,000 grant from the National Institutes of Health (NIH).

Gene May Hold Key to Hearing Recovery

Researchers have discovered that a protein implicated in human longevity may also play a role in restoring hearing after noise exposure. The findings, where were published in the journal Scientific Reports, could one day provide researchers with new tools to prevent hearing loss.

The study reveals that a gene called Forkhead Box O3 (Foxo3) appears to play a role in protecting outer hair cells in the inner ear from damage. The outer hair cells act as a biological sound amplifier and are critical to hearing. When exposed to loud noises, these cells undergo stress. In some individuals, these cells are able to recover, but in others the outer hair cells die, permanently impairing hearing. While hearing aids and other treatments can help recovered some range of hearing, there is currently no biological cure for hearing loss.

“While more than a hundred genes have been identified as being involved in childhood hearing loss, little is known about the genes that regulate hearing recovery after noise exposure,” said Patricia White, Ph.D., a research associate professor in the University of Rochester Medical Center Department of Neuroscience and lead author of the study. “Our study shows that Foxo3 could play an important role in determining which individuals might be more susceptible to noise-induced hearing loss.”

in preparation for the next round of training.

Patients who went partially blind after suffering a stroke regained large swaths of rudimentary sight after undergoing visual training designed by researchers at the University of Rochester Medical Center’s Flaum Eye Institute.

A new study out today in Neurology®, the medical journal of the American Academy of Neurology, provides the first evidence that rigorous visual training recovers basic vision in cortically blind patients with long-standing stroke damage in the primary visual cortex. Damage to this area of the brain prevents visual information from getting to other brain regions that help make sense of it, causing loss of sight in one-quarter to one-half of an individual’s normal field of view. Somewhere between 250,000 and 500,000 people suffer vision loss due to damage to the visual cortex each year.

“We are the only people in the U.S. currently using this type of training to recover vision lost after damage to the primary visual cortex,” said study senior author Krystel Huxlin, Ph.D., director of Research and James V. Aquavella, M.D. Professor of Ophthalmology at URMC’s Flaum Eye Institute. “If you talk to the majority of clinicians, they still believe nothing can be done.”

Study Shed New Light on Brain’s Decision-making Process

New research reveals the complex circuits involved in regulating the neurotransmitter dopamine in our brains. Traditionally thought to be limited to reward seeking, the new study shows that parts of the ‘emotional’ brain may also manipulate dopamine to help us pay attention and react to new information in the environment.

The study, which appears in the journal Neuropsychopharmacology, was led by Julie Fudge, M.D., with the University of Rochester Medical Center (URMC) Department of Neuroscience.

The research focuses on an area of the brain called the amygdala, which is known to be important for social and emotional development and behaviors. The amygdala receives sensory information – sight, sound, and smells – and processes it by combining it with information stored in our memories. It evaluates changes or new information to help determine whether it is worthy of our attention or if it can be ignored. The new study shows that one way the amygdala can accomplish this is by communicating with the brain’s dopamine producing cells.
