Study Points to Possible New Therapy for Hearing Loss

Monday, October 15, 2018

Photo of elderly manResearchers 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 Department of Biology and a co-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.

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.

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."

Academic Stories, a division of Academic Media Group, aims to inspire more people to pursue academic careers by sharing groundbreaking research and the people and places that make it possible. Academic Stories brings their stories to a larger audience in an accessible way.

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."

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.

Martina Poletti Awarded University Furth Fund

Friday, April 13, 2018

The Furth Fund, established through the generosity of Valerie and Frank Furth, provides early career scientists with $10,000 in research funds. The funds are used to promote the research activities of the faculty member, which may include the purchase of new equipment or support for graduate students or postdocs.

Dr. Poletti studies the “finely orchestrated interplay between sensory processing, the control of motor behavior, and the allocation of attentional resources” in enabling visual perception, with a particular interest in fine spatial vision processes in the foveola. This is a small high-acuity region of the retina that humans use to inspect objects of interest. Foveal vision is fundamental for normal functioning, yet surprisingly little is known about its mechanisms.

Poletti “strongly exemplifies the highest professional qualities of a junior, tenure track faculty member: productive, innovative researcher with an early and strong publication track record in highly competitive and visible journals; and, highly-competitive grant funding,” says John Foxe, director of the Ernest J. Del Monte Institute for Neuroscience and chair of neuroscience. “Her background and research on human visual perception, attention, and oculomotor control enrich the Department of Neuroscience and complement well the research programs of fellow faculty members.”

Congratulations Martina!!

New Career Development Awardees to Study Suicide Prevention and Neural Processing

Monday, March 12, 2018

Kevin Mazurek, Ph.D., postdoctoral fellow in the Department of Neurology at URMC, will investigate how areas of the brain communicate information about how and why movements are performed and how neurologic diseases such as epilepsy affect this communication.

Electrophysiological techniques allow for investigating which cortical areas communicate information related to the performance of voluntary movements. For his KL2 project, Dr. Mazurek will analyze changes in neural communication as participants perform the same hand and finger movements when instructed with different sensory cues (e.g. visual, auditory). He will compare healthy individuals and individuals with intractable epilepsy to identify changes in neural communication pathways. Identifying the exact nature in which epileptic activity affects cortical communication could lead to a biomarker for the appropriate connections to target for rehabilitative treatment.

Professor Studies Complex Brain Networks Involved in Vision

Monday, March 12, 2018

Our brains are made up of an intricate network of neurons. Understanding the complex neuronal circuits—the connections of these neurons—is important in understanding how our brains process visual information.

Farran Briggs, a new associate professor of neuroscience and of brain and cognitive sciences at the University of Rochester, studies neuronal circuits in the brain’s vision system and how attention affects the brain’s ability to process visual information.

Previously a professor at the Geisel School of Medicine at Dartmouth, Briggs became interested in neuroscience in high school. “I took a class and just became really fascinated by the brain and how it works,” she says. Today, her research on the fundamental levels of vision may provide new insight on impairments associated with attention deficit disorders.

Biological Sex Tweaks Nervous System Networks, Plays Role in Shaping Behavior

Thursday, March 8, 2018

By Mark Michaud

New research published today in the journal Current Biology demonstrates how biological sex can modify communication between nerve cells and generate different responses in males and females to the same stimulus. The findings could new shed light on the genetic underpinnings of sex differences in neural development, behavior, and susceptibility to diseases.

“While the nervous systems of males and females are virtually identical, we know that there is a sex bias in how many neurological diseases manifest themselves, that biological sex can influence behavior in animals, and that some of these differences are likely to be biologically driven,” said Douglas Portman, Ph.D., an associate professor in the Departments of Biomedical Genetics, Neuroscience, and the Center for Neurotherapeutics Discovery at the University of Rochester Medical Center (URMC) and lead author of the study. “This study demonstrates a connection between biological sex and the control and function of neural circuits and that these different sex-dependent configurations can modify behavior.”

The findings were made in experiments involving the nematode C. elegans, a microscopic roundworm that has long been used by researchers to understand fundamental mechanisms in biology. Many of the discoveries made using these worms apply throughout the animal kingdom and this research has led to a broader understanding of human biology. In fact, three Nobel Prizes in medicine and chemistry have been awarded for discoveries involving C. elegans.

The study focuses on the different behaviors of male and female worms. There are two sexes of C. elegans, males and hermaphrodites. Although the hermaphrodites are able to self-fertilize, they are also mating partners for males, and are considered to be modified females.

The behavior of C. elegans is driven by sensory cues, primarily smell and taste, which are used by the worms to navigate their environment and communicate with each other. Female worms secrete a pheromone that is known to attract males who are drawn by this signal in search of a mate. Other females, however, are repelled by the same pheromone. It is not entirely understood why, but scientists speculate that that the pheromone signals to females to avoid areas where there may be too much competition.

Brain Signal Indicates When You Understand What You’ve Been Told

During everyday interactions, people routinely speak at rates of 120 to 200 words per minute. For a listener to understand speech at these rates – and not lose track of the conversation – the brain must comprehend the meaning of each of these words very rapidly.

“That we can do this so easily is an amazing feat of the human brain – especially given that the meaning of words can vary greatly depending on the context,” says Edmund Lalor, associate professor of biomedical engineering and neuroscience at the University of Rochester and Trinity College Dublin. “For example, ‘I saw a bat flying overhead last night’ versus ‘the baseball player hit a home run with his favorite bat.’”

Now, researchers in Lalor’s lab have identified a brain signal that indicates whether a person is indeed comprehending what others are saying – and have shown they can track the signal using relatively inexpensive EEG (electroencephalography) readings taken on a person’s scalp.

Training brains—young and old, sick and healthy—with virtual reality

Tuesday, February 13, 2018

An accidental discovery by Rochester researchers in 2003 touched off a wave of research into the area of neuroplasticity in adults, or how the brain’s neural connections change throughout a person’s lifespan.

Fifteen years ago, Shawn Green was a graduate student of Daphne Bavelier, then an associate professor of brain and cognitive sciences at the University. As the two created visual tests together, Green demonstrated exceptional proficiency at taking these tests himself. The two researchers hypothesized that it might be due to his extensive experience playing first-person, action-based video games. From there, Green and Bavelier demonstrated that, indeed, action-based video games enhance the brain’s ability to process visual information.

In years since, video gaming technology has gotten more sophisticated, regularly incorporating or featuring virtual reality (VR). The Oculus Rift headset, for example, connects directly to your PC to create an immersive VR gaming experience.

If we know that action-based video games enhance visual attention, might VR games do the same (and perhaps to a greater degree) because of the increased level of immersion?

That’s the question a current group of Rochester researchers—Duje Tadin, associate professor of brain and cognitive sciences; Jeffrey Bazarian, professor of emergency medicine; and Feng (Vankee) Lin, assistant professor in the School of Nursing—hope to answer.

In Wine, There’s Health: Low Levels of Alcohol Good for the Brain

Friday, February 2, 2018

By Mark Michaud

While a couple of glasses of wine can help clear the mind after a busy day, new research shows that it may actually help clean the mind as well. The new study, which appears in the journal Scientific Reports, shows that low levels of alcohol consumption tamp down inflammation and helps the brain clear away toxins, including those associated with Alzheimer’s disease.

“Prolonged intake of excessive amounts of ethanol is known to have adverse effects on the central nervous system,” said Maiken Nedergaard, M.D., D.M.Sc., co-director of the Center for Translational Neuromedicine at the University of Rochester Medical Center (URMC) and lead author of the study. “However, in this study we have shown for the first time that low doses of alcohol are potentially beneficial to brain health, namely it improves the brain’s ability to remove waste.”

The finding adds to a growing body of research that point to the health benefits of low doses of alcohol. While excessive consumption of alcohol is a well-documented health hazard, many studies have linked lower levels of drinking with a reduced risk of cardiovascular diseases as well as a number of cancers.

Lungs Mays Hold Key to Thwarting Brain Damage after a Stroke

Wednesday, January 31, 2018

By Mark Michaud

The harm caused by a stroke can be exacerbated when immune cells rush to the brain an inadvertently make the situation worse. Researchers at the University of Rochester Medical Center (URMC) are studying new ways to head off this second wave of brain damage by using the lungs to moderate the immune system’s response.

“It has become increasingly clear that lungs serve as an important regulator of the body’s immune system and could serve as a target for therapies that can mitigate the secondary damage that occurs in stroke,” said URMC neurologist Marc Halterman, M.D., Ph.D. “We are exploring a number of drugs that could help suppress the immune response during these non-infection events and provide protection to the brain and other organs.”

Halterman’s lab, which is part of the Center for NeuroTherapeutics Discovery, has been investigating domino effect that occurs after cardiac arrest. When blood circulation is interrupted, the integrity of our intestines becomes compromised, releasing bacteria that reside in the gut into the blood stream. This prompts a massive immune response which can cause systemic inflammation, making a bad situation worse.

While looking at mouse models of stroke, his lab observed that a similar phenomenon occurs. During a stroke blood vessels in the brain leak and the proteins that comprise the wreckage of damaged neurons and glia cells in the brain make their way into blood stream. The immune system, which is not used to seeing these proteins in circulation, responds to these damage-associated molecular patterns and ramps up to respond. Mobilized immune cells make their way into the brain and, finding no infection, nevertheless trigger inflammation and attack healthy tissue, compounding the damage.

The culprit in this system-wide immune response is neutrophils, a white cell in the blood system that serves as the shock troops of the body’s immune system. Because our entire blood supply constantly circulates through the lungs, the organ serves as an important way station for neutrophils. It is here that the cells are often primed and instructed to go search for new infections. The activated neutrophils can also cause inflammation in the lungs, which Halterman suspects may be mistakenly identified as post-stroke pneumonia. The damage caused by activated neutrophils can also spread to other organs including the kidneys, and liver.

Stowell Brain Painting

The complex biology, networks, and symphony of signals that underlie human cognition are a font of endless mystery and wonder to those who study it.  For Rianne Stowell, a graduate student in the lab of URMC neuroscientist Ania Majewska, Ph.D., these questions are also a source of artistic inspiration which has led to the creation of striking paintings of the brain’s inner workings.

Stowell’s most recent creation (above) is based on research which has recently been published in the journal Developmental Neurobiology and sheds new light on the role that immune cells called microglia play in wiring and rewiring the connections between nerve cells.

Stowell recalls wanting to pursue a career in art as far back as elementary school in Pennsylvania and while she carried that desire with her to Moravian College, she also began to explore other academic fields. Her interest in biology and psychology attracted her to a degree in neuroscience and that decision ultimately led her to the University of Rochester School of Medicine and Dentistry, where she is in now in her fourth year of graduate studies in pursuit of her Ph.D. in neuroscience.

Introducing a New Faculty Member

Friday, January 5, 2018

Michele Rucci has joined the Department of Brain and Cognitive Sciences as a professor after serving as a professor of psychological and brain sciences at Boston University. Rucci’s research program combines experimental and theoretical approaches to study mechanisms of visual perception. His primary interests lie in the elucidation of how motor and sensory processes interact in the human brain and how motor behavior contributes to the extraction and processing of visual information. Rucci and his colleagues have explained the functional roles of microscopic eye movements that take place while we fixate on an object of interest. He has demonstrated that these miniature eye movements play important roles in reformatting the visual input to be processed efficiently and for systematically exploring objects during tasks that require high spatial precision. He received Laurea (MA) and PhD degrees in biomedical engineering from the University of Florence and the Scuola Superiore S. Anna in Pisa, respectively. Before joining the faculty of Boston University, he was a fellow in computational neuroscience at the Neurosciences Institute in San Diego.
