Maiken Nedergaard Recognized for Groundbreaking Research on Glymphatic System
Tuesday, November 13, 2018
Maiken Nedergaard, M.D., D.M.Sc., has been awarded the with the 2018 Eric K. Fernstrom Foundation Grand Nordic Prize for her work that led to the discovery of the brain’s unique waste removal system and its role in a number of neurological disorders. Nedergaard maintains labs at the Medical Center and the University of Copenhagen.
In 2012, Nedergaard’s lab was the first to reveal the brain’s unique process of removing waste, dubbed the glymphatic system, which consists of a plumbing system that piggybacks on the brain’s blood vessels and pumps cerebral spinal fluid (CSF) through the brain’s tissue, flushing away waste.
Nedergaard’s lab has since gone on to show that the glymphatic system works primarily while we sleep, could be a key player in diseases like Alzheimer’s, is disrupted after traumatic brain injury, may be enhanced by moderate alcohol consumption, and could be harnessed as a new way to deliver drugs to the brain.
The Eric K. Fernstrom Foundation annually awards the Grand Nordic Prize to a medical research from one of the Nordic Countries. The award was announced during a ceremony on November 7 at Lund University in Sweden.Read More: Maiken Nedergaard Recognized for Groundbreaking Research on Glymphatic System
Study: Attention Requires Balance in the Brain
Monday, October 29, 2018
The ability to focus attention is a fundamental challenge that the brain must solve and one that is essential to navigating our daily lives. In developmental disorders such as Autism this ability is impaired. New research published in the journal Nature Communications shows that nerve cells maintain a state of balance when preparing to interpret what we see and this may explain why the healthy brain can block out distractions.
The new research, which was co-authored by Adam Snyder, Ph.D., an assistant professor in the University of Rochester Department of Brain and Cognitive Sciences and UR Medicine Del Monte Institute for Neuroscience, marks a departure from the established view of how the brain tackles the task of identifying what is important.
“The visual world contains more information than our brains can handle,” said Snyder. “This research shows that when anticipating stimulus, the brain maintains a pattern consisting of stimulated and unstimulated neurons and that these patterns differ from when the brain is actually processing information.”
While it is known that the process of paying attention amplifies neural signals in the brain in order to prepare for relevant information, how the brain achieves this state of readiness remains unknown. One theory that has gained acceptance among the neuroscience community is that the nerve cells in the brain anticipate stimuli and maintain a heightened state of readiness.
“The prevailing view is that something happens to activate neurons so they will amplify the response to stimuli, like turning up the stereo so when the music starts it is already louder,” said Snyder. “Our suspicion is that the brain doesn’t work this way because the problem when you crank up the volume is you also get static noise.”
Disorders like Autism are characterized by the inability to parse through stimuli and identify what is important. This is often manifested in oversensitivity to certain visual or auditory environments where the brain has difficulty in separating the relevant information from ‘static.’ Over time, this inability to focus and block out distractions can give rise to atypical social behavior.Read More: Study: Attention Requires Balance in the Brain
New Research Seeks to Understand Link Between Iron and Brain Development
Wednesday, October 24, 2018
Iron deficiency is the one of the most prevalent nutritional deficiencies in the world and affects mainly pregnant mothers and young children. Numerous studies have found that mothers who have low iron levels during pregnancy, have a higher risk of giving birth to a child that develops cognitive impairments like autism, attention deficit syndrome, and learning disabilities. While the link between gestational iron deficiency (GID) and cognitive impairment in offspring is well establish, the mechanisms by which this occurs remain unknown.
Margot Mayer-Proschel, Ph.D., an associate professor in the University of Rochester Medical Center (URMC) Department of Biomedical Genetics, has established animal models of GID and was the first to pinpoint the critical periods of gestation during which the developing central nervous system is most vulnerable to GID. Her laboratory recently demonstrated that nerve cells in the brains of animals born to iron deficient mice behave abnormally to excitatory brain stimuli and has shown that functional impairments cannot be restored by iron supplements later in life.Read More: New Research Seeks to Understand Link Between Iron and Brain Development

Personable, with a self-deprecating humor, David Dodell-Feder undertakes research that belies his easy-going manner. A new assistant professor in the University’s psychology department with a secondary appointment in neuroscience, he studies the processes that underlie how humans navigate the social world and how those processes go awry in people with schizophrenia.
Every human’s physical and mental constitution demands social connection and social contact, but “large numbers of people don’t have that social connection and therefore don’t get to reap the benefits of having close social relationships,” says Dodell-Feder. That’s why people with schizophrenia have trouble forming, establishing, and maintaining healthy social relationships, romantic relationships, and relationships at work.Read More: Peering Into What Goes Awry in Schizophrenia
Study Points to New Method to Deliver Drugs to the Brain
Thursday, October 18, 2018
Researchers at the University of Rochester Medical Center (URMC) have discovered a potentially new approach to deliver therapeutics more effectively to the brain. The research could have implications for the treatment of a wide range of diseases, including Alzheimer’s, Parkinson’s, ALS, and brain cancer.
“Improving the delivery of drugs to the central nervous system is a considerable clinical challenge,” said Maiken Nedergaard M.D., D.M.Sc., co-director of the University of Rochester Medical Center (URMC) Center for Translational Neuromedicine and lead author of the article which appears today in the journal JCI Insight. “The findings of this study demonstrate that the brain’s waste removal system could be harnessed to transport drugs quickly and efficiently into the brain.”
Many promising therapies for diseases of the central nervous system have failed in clinical trials because of the difficulty in getting enough of the drugs into the brain to be effective. This is because the brain maintains its own closed environment that is protected by a complex system of molecular gateways – called the blood-brain barrier – that tightly control what can enter and exit the brain.Read More: Study Points to New Method to Deliver Drugs to the Brain
Study Points to Possible New Therapy for Hearing Loss
Monday, October 15, 2018
Researchers have taken an important step toward what may become a new approach to restore the hearing loss. In a new study, out today in the European Journal of Neuroscience, scientists have been able to regrow the sensory hair cells found in the cochlea – a part of the inner ear – that converts sound vibrations into electrical signals and can be permanently lost due to age or noise damage.
Hearing impairment has long been accepted as a fact of life for the aging population – an estimated 30 million Americans suffer from some degree of hearing loss. However, scientists have long observed that other animals – namely birds, frogs, and fish – have been shown to have the ability to regenerate lost sensory hair cells.
“It’s funny, but mammals are the oddballs in the animal kingdom when it comes to cochlear regeneration,” said Jingyuan Zhang, Ph.D., with the University of Rochester Medical Center (URMC) Department of Neuroscience and first author of the study. “We’re the only vertebrates that can’t do it.”
Research conducted in the lab of Patricia White, Ph.D., in 2012 identified a family of receptors – called epidermal growth factor (EGF) – responsible for activating support cells in the auditory organs of birds. When triggered, these cells proliferate and foster the generation of new sensory hair cells. She speculated that this signaling pathway could potentially be manipulated to produce a similar result in mammals. White is a research associate professor in the University of Rochester Medical Center (URMC) Del Monte Institute for Neuroscience and lead author of the current study.Read More: Study Points to Possible New Therapy for Hearing Loss

Professors Anne Luebke and Ross Maddox receive NSF award
Tuesday, October 2, 2018
BME Professors Anne Luebke and Ross Maddox along with Co-PI Elizabeth Marvin (Eastman School of Music) have received an award from the National Science Foundation for their project, "NeuroDataRR. Collaborative Research: Testing the relationship between musical training and enhanced neural coding and perception in noise.” This is a collaborative effort involving several universities: University of Minnesota (Dr. Andrew Oxenham, Lead PI), Purdue University, Carnegie Mellon University, Boston University, University of Western Ontario, and the University of Rochester.
This project will determine whether formal musical training is associated with enhanced neural processing and perception of sounds, including speech in noisy backgrounds. Music forms an important part of the lives of millions of people around the world, and it is one of the few universals shared by all known human cultures. Yet its utility and potential evolutionary advantages remain a mystery. This project will test the hypothesis that early musical exposure has benefits that extend beyond music to critical aspects of human communication, such as speech perception in noise. In addition, this project will test whether early musical training is associated with less severe effects of ageing on the ability to understand speech in noisy backgrounds. Degraded ability to understand speech in noise is a common complaint among older listeners, and one that can have a profound impact on quality of life, as has been shown by the associations between hearing loss, social isolation, and more rapid cognitive and health declines. If formal musical training is shown to be associated with improved perception and speech communication in later life, the outcomes could have a potentially major impact on many aspects of public and educational policy.
UR Medicine Unveils Upstate New York’s First Mobile Stroke Unit
Thursday, September 27, 2018
Next month, UR Medicine will begin operation of a Mobile Stroke Unit (MSU), a high-tech ‘emergency room on wheels’ that is designed to provide life-saving care to stroke victims. The $1 million unit will be operated in partnership with AMR as a community resource and represents a significant step forward for stroke care in the Rochester region.
While the MSU resembles an ambulance on the outside, inside it contains highly specialized staff, equipment, and medications used to diagnose and treat strokes. The unit is equipped with a portable CT scanner that is capable of imaging the patient’s brain to detect the type of stroke they are experiencing. The scans and results from a mobile lab on the unit are wirelessly transmitted to UR Medicine stroke specialists at Strong Memorial Hospital, who will consult with the on board EMS staff via telemedicine and decide if they can begin treatment immediately on scene.
If it is determined that the patient is experiencing an ischemic stroke – which account for approximately 90 percent of all strokes – the MSU team can administer the drug tissue plasminogen activator (tPA) to attempt to break up the clot in the patient’s brain. While en route to the hospital, UR Medicine specialists will continue to remotely monitor and assess the patient’s symptoms.
“The UR Medicine Mobile Stroke Unit essentially brings the hospital to the patient,” said neurosurgeon Tarun Bhalla, M.D., Ph.D., with the UR Medicine Comprehensive Stroke Center. “This unit will improve care and outcomes by shortening the gap between diagnosis and treatment and enable us to initiate care before the patient reaches the hospital.”
It is estimated that 3,000 people in Monroe County suffer from a stroke every year. Stroke is the fifth leading cause of death and the number one cause of long-term disability in the U.S. However, if caught early, many stroke victims can make a full recovery.
“Ten years ago we realized there was an epidemic of stroke in our community which resulted in tremendous human suffering and health care costs,” said Web Pilcher, M.D., Ph.D., chair of the UR Medicine Department of Neurosurgery. “We decided to embark on a long-term plan to provide the best stroke care in upstate New York. The Mobile Stroke Unit represents the next evolution in that effort and places Rochester among an elite list of communities with this cutting-edge technology.”
The current best treatment for stroke is tPA. But in order to work properly, the drug must be given within four and half hours of the first stroke symptoms. Depending upon the circumstances, doctors may also elect to perform a minimally invasive endovascular surgical procedure that involves threading a catheter through the blood vessels and physically removing the obstruction in the brain. The capabilities provided by the MSU to diagnose, start treatment, and prepare hospital staff to receive the patient before they arrive at the emergency department will save lives and improve chances of recovery.
“In stroke care, time equals brain,” said neurologist Curtis Benesch, M.D., M.P.H., with the UR Medicine Comprehensive Stroke Center. “The approximately 30 minutes that could be saved by the Mobile Stroke Unit by starting treatment before a stroke patient reaches the hospital could mean the difference between the recovery of function or a lifetime of impairment.”
“Patients who receive tPA sooner are more likely to go home and retain the ability to walk and care for themselves,” said Bob Holloway, M.D., M.P.H., chair of the UR Medicine Department of Neurology. “The Mobile Stroke Unit will improve outcomes for stroke victims in our community and, because people with less disability use fewer health care resources, lower costs in the long term.”
The unit is owned by UR Medicine and will be operated by AMR. The MSU will be staffed by a UR Medicine nurse trained in stroke care and a CT technician, an AMR paramedic and emergency medical technician, and remotely by a stroke specialist at UR Medicine.
The construction and operating costs of the unit, which was custom built by Frazer Ltd. in Houston, are being funded by UR Medicine and philanthropy, including a lead gift from Elena Prokupets and support from the Del Monte family and other donors in the Rochester community.
“We are extremely grateful to Elena for her gift to the School of Medicine and Dentistry, which has made it possible to bring this life saving technology to Rochester,” said Mark Taubman, M.D., CEO of the University of Rochester Medical Center. “Her generosity, along with the support of many others, has provided us the resources to invest in the infrastructure, technology, and clinical talent necessary to provide the most advanced stroke care to our community.”
The MSU is part of a broader UR Medicine initiative to bring state-of-the-art stroke care to the region. This includes Strong Memorial Hospital’s designation as the region’s only Comprehensive Stroke Center by the Joint Commission, a certification that indicates that the hospital either meets or exceeds the highest standards of care required to provide timely, advanced, and coordinated care to patients with cerebrovascular disease, and the Neuromedicine Intensive Care Unit, a 12-bed ICU that provides care to critically ill patients with complex neurological life threating illnesses such as stroke. UR Medicine stroke specialists also provide 24/7 consultation services for emergency department personnel in several hospitals in the region via telemedicine.
Eight years ago, UR Medicine, in partnership with the Greater Rochester Health Foundation, created the Stroke Treatment Alliance of Rochester/New York (STAR-NY), to educate medical professionals and the broader community about stroke recognition and prevention.Read More: UR Medicine Unveils Upstate New York’s First Mobile Stroke Unit

Researchers Harness Virtual Reality, Motion Capture to Study Neurological Disorders
Wednesday, September 5, 2018
Neuroscientists at the University of Rochester Medical Center (URMC) have a powerful new state-of-the-art tool at their disposal to study diseases like Autism, Alzheimer’s, and traumatic brain injury. The Mobile Brain/Body Imaging system, or MoBI, combines virtual reality, brain monitoring, and Hollywood-inspired motion capture technology, enabling researchers to study the movement difficulties that often accompany neurological disorders and why our brains sometimes struggle while multitasking.
“Many studies of brain activity occur in controlled environments where study subjects are sitting in a sound proof room staring at a computer screen,” said John Foxe, Ph.D., director of the URMC Del Monte Institute for Neuroscience. “The MoBI system allows us to get people walking, using their senses, and solving the types of tasks you face every day, all the while measuring brain activity and tracking how the processes associated with cognition and movement interact.”
The MoBI platform – which is located in the Del Monte Institute’s Cognitive Neurophysiology Lab – brings together several high tech systems. Using the same technology that is employed by movie studios to produce CGI special effects, study participants wear a black body suite that is fitted with reflective markers. Participants are then asked to walk on a treadmill or manipulate objects at a table in a room fitted out with 16 high speed cameras that record the position of the markers with millimeter precision. This data is mapped to a computer generated 3D model that tracks movement.

Fourth year NGP Graduate Student Publishes in Journal of Neuroscience
Tuesday, May 29, 2018
Fourth year NGP graduate student Patrick Miller-Rhodes (Gelbard lab) has recently published a single author review in Journal of Neuroscience (Journal Club, J Neurosci. 2018 38(19):4457– 4459) tackling the fascinating and timely topic of the heterogeneity of microglial mechanisms that contribute to normal brain functions such as synaptic plasticity. In this publication, Patrick highlights a recent study by NGP alumna Rebecca Lowery (Majewska lab; Glia 65(11):1744-1761), showing that microglial CX3CR1 loss does not affect multiple forms of plasticity, to make his point that the mechanisms microglia use to support neuronal function are likely diverse and differ based on brain region and developmental stage.
Congratulations Patrick and go NGP!

URMC Researcher Featured in Academic Stories
Tuesday, May 29, 2018
Kevin Mazurek, PhD recently gave an interview for the online Academic Stories blog, entitled "Researchers Discover How to Inject Instructions into the Premotor Cortex".
"Thanks to our brain’s complex network of connections, we are able to effortlessly move through and react to the world around us. But for people with strokes or traumatic brain injuries, these connections are disrupted making some basic functions challenging. Kevin Mazurek and his mentor Marc Schieber at the University of Rochester have made a discovery with the potential to help restore neural connections in patients. They have found a way to “inject” information directly into the premotor cortex of two rhesus monkeys, bypassing the visual centres."

Each year the committee invites an accomplished neuroscientist to present a lecture that will address in some way how the workings of the mind derive from neuronal activity. The intent of the Lecture is to appeal to a wide and diverse audience to include all interested in the neural sciences – faculty, alumni, students, and other scholars.
Brain Science Suggests This Is the Best Position to Sleep In
Thursday, May 17, 2018
Sleep is critical for rest and rejuvenation. A human being will actually die of sleep deprivation before starvation--it takes about two weeks to starve, but only 10 days to die if you go without sleep.
The CDC has also classified insufficient sleep as a public health concern. Those who don't get enough sleep are more likely to suffer from chronic diseases that include hypertension, diabetes, depression, obesity, and cancer.
It's thus vital to get enough shuteye, but it turns out your sleep position also has a significant impact on the quality of rest you get.
In addition to regulating one's appetite, mood, and libido, neuroscientists assert that sleep reenergizes the body's cells, aids in memory and new learning, and clears waste from the brain.
That last one is particularly important. Similar to biological functions in which your body clears waste, your brain needs to get rid of unwanted material. The more clearly it functions, the more clearly you do.
Now, a neuroscience study suggests that of all sleep positions, one is most helpful when it comes to efficiently cleaning out waste from the brain: sleeping on your side.
The study, published in the Journal of Neuroscience, used dynamic contrast-enhanced MRI to image the brain's "glymphatic pathway." This is the system by which cerebrospinal fluid filters through the brain and swaps with interstitial fluid (the fluid around all other cells in the body).
The exchange of the two fluids is what allows the brain to eliminate accumulated waste products, such as amyloid beta and tau proteins. What are such waste chemicals associated with? Among other conditions, Alzheimer's and Parkinson's.
"It is interesting that the lateral [side] sleep position is already the most popular in humans and most animals--even in the wild," said University of Rochester's Maiken Nedergaard. "It appears that we have adapted the lateral sleep position to most efficiently clear our brain of the metabolic waste products that build up while we are awake."Read More: Brain Science Suggests This Is the Best Position to Sleep In
Rochester Research Cited in Psychology Today Article
Monday, May 14, 2018
Work in the Schieber lab by Marc Schieber and Kevin Mazurek was included in "The Sensory Revolution" in Psychology Today.
Our senses are under constant threat from the stimuli, routines, and ailments of the modern world. Fortunately, neuroscience is inspiring remedies that not only restore sensory input but radically alter it.
Sometimes sensation makes its way to the brain but doesn't alter behavior because the brain's wiring fails, as in stroke or localized brain damage. Neuroscientists Marc Schieber and Kevin Mazurek, both at the University of Rochester, have demonstrated a method that might bypass these downed lines. They've trained two monkeys to perform four instructed actions, such as turning a knob or pressing a button. But that instruction takes the form of an electrical signal sent to electrodes in the monkeys' premotor cortex, an area between the sensory cortices and the motor cortex, which controls muscle movement. Even without any sensory instruction, the monkeys were nearly 100 percent accurate at interpreting the signal and performing the correct action.Read More: Rochester Research Cited in Psychology Today Article
