    NASA Grant Will Explore Impact of Space Travel on the Brain

    M. Kerry O'Banion

    Kerry O'Banion, M.D., Ph.D., has been awarded $1.8 million from NASA to study whether extended deep space travel places astronauts at risk for neuro-degenerative diseases like Alzheimer's.

    The grant is one of nine announced by NASA that will fund research that employ beams of high-energy, heavy ions simulating space radiation. The studies will be conducted in part at the NASA Space Radiation Laboratory at Brookhaven National Laboratory on Long Island. By colliding matter together at very high speeds, the accelerators at Brookhaven can reproduce the radioactive particles found in space.

    The studies will seek to better understand and reduce the risks to humans associated with long journeys in deep space, specifically focusing on neurological and cardiovascular diseases and cancer. Understanding the potential health impact of space travel is a priority for NASA as it develops future plans for maned voyages to Mars and other destinations.

    What 'Drives' Curiosity Research?

    Scientists have been studying curiosity since the 19th century, but combining techniques from several fields now makes it possible for the first time to study it with full scientific rigor, according to the authors of a new paper.

    Benjamin Hayden and Celeste Kidd, researchers in brain and cognitive sciences at the University of Rochester, are proposing that scientists utilize these techniques to focus on curiosity's function, evolution, mechanism, and development, rather than on what it is and what it isn't.

    Curiosity is a long-standing problem that is fascinating, but has been difficult to approach scientifically, said Hayden, an assistant professor and co-author of a Perspective article published today in Neuron.

    Study: Brain's Immune System Could Be Harnessed to Fight Alzheimer's

    M. Kerry O'BanionA new study appearing in the Journal of Neuroinflammation suggests that the brain's immune system could potentially be harnessed to help clear the amyloid plaques that are a hallmark of Alzheimer's disease.

    This research confirms earlier observations that, when activated to fight inflammation, the brain's immune system plays a role in the removal of amyloid beta, said M. Kerry O'Banion, M.D., Ph.D., a professor in the University of Rochester Department of Neurobiology and Anatomy, the Del Monte Neuromedicine Institute, and the lead author of the study. We have also demonstrated that the immune system can be manipulated in a manner that accelerates this process, potentially pointing to a new therapeutic approach to Alzheimer's disease.

    The findings are the culmination of years of investigation that were triggered when O'Banion and his colleagues made a surprising discovery while studying mouse models of Alzheimer's disease. They observed that amyloid beta plaques – which scientists believe play a major role in the disease – were being cleared in animals with chronic brain inflammation.

    URMC using photon laser for cancer research

    Edward BrownEdward Brown's research is a mixture of photonics, microscopes and a little nudge from his mom.

    Brown, who teaches biomedical engineering at the University of Rochester Medical Center, has built a laser-and-microscope device to study how likely cancer cells will spread throughout the body. Specifically, he's looking at how likely cancer cells have spread inside breast cancer patients who already have had the tumor removed.

    Learning more about the cell movement, called metastasis, is key to a larger overtreatment problem that Brown is trying to fix.

    When patients first realize they have breast cancer, it's unclear whether the cancer cells have spread, so doctors recommend chemotherapy as a precaution. However, Brown and other medical researchers believe patients are being overtreated because doctors are giving chemo to patients who may not need it.

    Clerio Vision licenses ground-breaking approach to vision correction developed by Huxlin, Knox and Ellis

    LASIK revolutionized vision correction in the 1990s. Now, a new technology arising from research conducted by Wayne Knox, Professor of Optics and Physics; Krystel Huxlin, Professor of Ophthalmology; and Jonathan Ellis, Assistant Professor of Mechanical Engineering, may do the same, notes UR Ventures Technology Review.

    Known as LIRIC (Laser Induced Refractive Index Change), this ground-breaking method also uses a laser to correct the optical properties of the eye, but that's where the similarities to LASIK end.

    The older technology uses two lasers and includes cutting the cornea to create a flap and then pulling that flap back to expose the inner cornea. A laser is then applied to ablate and reshape the corneal tissue to achieve the desired focus. The corneal flap is repositioned and the healing process begins. Complications are rare, but as with any surgery, are a concern. Fear of complications and of having one's eye cut are big reasons why less than 2 percent of people who are eligible for LASIK undergo the procedure.

    The LIRIC method uses a laser at a much lower power and does not cut or remove any tissue. Instead, it is a non-invasive procedure that alters the refractive index of the corneal tissue to correct vision. Since the procedure doesn't thin the cornea like LASIK, it may be repeated many times over the course of a patient's lifetime as the eye grows and changes.

    This technology has been licensed to Clerio Vision, Inc., a local startup poised to bring this new treatment to market. Clerio was started by a team of entrepreneurs with proven track records - Mikael Totterman (VirtualScopics, iCardiac), Alex Zapesochny (Lenel, iCardiac), Scott Catlin (AMO, Abbott Medical Optics - and now with UR Ventures), and Sasha Latypova (VirtualScopics, iCardiac). The company successfully concluded an oversubscribed Series A round of fundraising with participation from three venture capital firms, and is considering a Series B round to further accelerate product and clinical development. They have proven efficacy in animal models and hydro-gels (contact lenses), and plan to conduct human studies early in 2016.

    Experimental Treatment Regimen Effective Against HIV

    Protease inhibitors are a class of antiviral drugs that are commonly used to treat HIV, the virus that causes AIDS. Scientists at the University of Nebraska Medical Center designed a new delivery system for these drugs that, when coupled with a drug developed at the University of Rochester School of Medicine and Dentistry, rid immune cells of HIV and kept the virus in check for long periods. The results appear in the journal Nanomedicine: Nanotechnology, Biology and Medicine.

    While current HIV treatments involve pills that are taken daily, the new regimens' long-lasting effects suggest that HIV treatment could be administered perhaps once or twice per year.

    Nebraska researcher Howard E. Gendelman designed the investigational drug delivery system–a so–called nanoformulated protease inhibitor. The nanoformulation process takes a drug and makes it into a crystal, like an ice cube does to water. Next, the crystal drug is placed into a fat and protein coat, similar to what is done in making a coated ice–cream bar. The coating protects the drug from being degraded by the liver and removed by the kidney.

    When tested together with URMC–099, a new drug discovered in the laboratory of UR scientist Harris A. (Handy) Gelbard M.D., Ph.D., the nanoformulated protease inhibitor completely eliminated measurable quantities of HIV. URMC–099 boosted the concentration of the nanoformulated drug in immune cells and slowed the rate at which it was eliminated, thereby prolonging its therapeutic effect.

    Carney lab looks beyond inner ear in quest for better hearing aids

    Laurel Carney, Ph.D.

    Most hearing aids on the market today are designed to mimic what happens in our inner ear - specifically the amplifying role of the outer hair cells.

    However, the lab of Laurel Carney, Professor of Biomedical Engineering, is studying what happens beyond the inner ear - in the complex network of auditory nerve fibers that transmit the inner ear's electrical signals to the brain, and in the auditory center of the midbrain, which processes those signals.

    Therein lies the key to creating hearing aids that not only make human speech louder but clearer, Carney believes.

    An important focus of her research uses a combination of physiological and behavioral studies, and computer modeling, to study the 30,000 auditory nerve fibers on each side of our brain that transmit electrical signals from the inner ear. Critical to this is the initial transduction of mechanical energy to electrical signals that occurs in the inner h air cells of the inner ear's organ of Corti.

    This is critical for shaping the patterning of responses in the auditory nerves, and the patterning of those responses at this first level, where the signal comes into the brain, has a big effect on the way the mid brain responds to the relatively low frequencies of the human voice, Carney explained.

    In people with healthy hearing, the initial transduction results in a wide contrast in how various auditory nerve fibers transmit this information. The responses of some fibers are dominated by a single tone, or harmonic, within the sound; others respond to fluctuations that are set up by the beating of multiple harmonics, Carney said. In the mid brain, neurons are capable of assimilating this contrast of fluctuating and nonfluctuating inputs across varying frequencies. They begin the process of parsing out the sounds of speech and any other vocalizations that involve low frequencies. A better understanding of how this process works in the midbrain, Carney believes, could yield new strategies for designing hearing aids.

    A lot of people have tried to design hearing aids based just on what is going on in the inner ear, but there's a lot of redundancies in the information generated there. We argue that you need to step back and, from the viewpoint of the midbrain, focus on what really matters. It's the pattern of fluctuations in the auditory nerve fibers that the midbrain responds to. The sort of strategies we're suggesting are not intuitive. The idea of trying to restore the contrast in the fluctuations across different frequency channels has not been tried before. The burden is on us to prove that it works, she added.

    To that end, Carney works closely with Joyce McDonough, Professor of Linguistics, in exploring how auditory nerve fiber transmissions play a role in coding speech sounds. Her lab also works closely with that of Jong-Hoon Nam, Assistant Professor of Mechanical Engineering and of Biomedical Engineering, whose inner-ear studies were described in this newsletter last week. Carney shares what her lab is learning about the interface of auditory nerve fiber signaling with the brain, and in return, we try to include in our models a lot of the nonlinear properties of the inner ear that he (Nam) has been working on. By interacting with his lab, we hope to continue to modernize our model as he discovers more, Carney said.

    FDA Approves Tool for Diagnosing Dementia in a Doctor's Office

    Dr. Charles Duffy M.D., Ph.D.

    A small company started by a neuroscientist at the University of Rochester has moved closer to providing doctors with what he says is a simple, computer-based tool to help detect early signs of Alzheimer's disease or other forms of dementia.

    Cerebral Assessment Systems has received marketing approval from the U.S. Food and Drug Administration for Cognivue, a cognitive-assessment tool that functions somewhat like a video game. A patient can perform the inexpensive and simple test while a time-strapped primary-care physician tends to other patients. The 10-minute, non­invasive examination can detect subtle lapses in the brain’s perceptual ability that may signal the early stages of mental decline caused by dementia.

    The federal government's approval to market the device comes as Alzheimer's researchers everywhere step up the pursuit for easier and more inexpensive ways to identify dementia in its earliest stages.

    Look, there is a late-life tsunami of late-life cognitive decline coming at us, and health-care providers are standing on the beach, said Charles J. Duffy, a neurology professor at the University of Rochester Medical Center who founded the company. What we are all about is making cognitive care part of primary care.

    Work of Liz Romanski Recognized by the University Research Community

    Dr. Lizabeth Romanski

    Researchers Pinpoint Brain's Audiovisual Processing Center

    A new study is helping scientists more precisely understand how the brain stitches together sensory information such as sound and images, insight that could shed new light on conditions such as Autism. The research, which appears in the Journal of Neuroscience, identifies an area of the brain in the frontal lobe responsible for working memory and sensory integration.

    Work in our laboratory is aimed at understanding how auditory and visual information are integrated since we know this process is crucial for recognizing objects by sight and sound, communicating effectively, and navigating through our complex world, said Lizabeth Romanski, Ph.D., an associate professor in the University of Rochester Department of Neurobiology and Anatomy and co-author of the study.

    Our recent study demonstrates that the prefrontal cortex plays an essential role in audiovisual working memory, and when this area is switched off our ability to remember both the auditory and visual cues is impaired, said Bethany Plakke, Ph.D., a postdoctoral fellow in the Romanski lab and co-author of this study.

    Babies' expectations may help brain development

    Infants can use their expectations about the world to rapidly shape their developing brains, researchers have found.

    A series of experiments with infants 5 to 7 months old has shown that portions of babies' brains responsible for visual processing respond not just to the presence of visual stimuli, but also to the mere expectation of visual stimuli, according to researchers from the University of Rochester and the University of South Carolina.

    That type of complex neural processing was once thought to happen only in adults—not infants—whose brains are still developing important neural connections.

    We show that in situations of learning and situations of expectations, babies are in fact able to really quickly use their experience to shift the ways different areas of their brain respond to the environment, said Lauren Emberson, who conducted the study at the University of Rochester's Baby Lab while a research associate with Richard Aslin in the department of brain and cognitive sciences.

    Researcher Wins Auditory Neuroscience Award

    Laurel Carney, Ph.D.

    Laurel Carney, a professor of Biomedical Engineering, has been recognized for her work by the premier scientific organization in the field of acoustics. The Acoustical Society of America has awarded Carney the William and Christine Hartmann Prize in Auditory Neuroscience.

    It's truly a great honor to receive an award created by Bill and Christine Hartmann, two of my role models, said Carney. I welcome the challenge to emulate their life of discovery, presentation, publication, service, and education throughout the world.

    William and Christine Hartmann established the award with a donation to recognize and honor research that links auditory physiology with auditory perception or behavior in humans or other animals. William Hartmann is a physicist, psychoacoustician, and former president of the Acoustical Society of America. His contributions to the field involved pitch perception, signal detection, modulation detection, and the localization of sound.

    In her research lab, Carney is working to better understand how the brain translates sounds into patterns of electrical impulses. By studying physiology, human hearing, and computer models, Carney hopes to learn how the brain distinguishes sounds in noisy environments and why even a small degree of hearing loss can lead to major problems. Her ultimate goal is to develop effective strategies to help people who have experienced hearing loss.

    Carney earned her M.S. and Ph.D. degrees in electrical engineering at the University of Wisconsin-Madison. She was an associate professor of biomedical engineering at Boston University and professor of biomedical engineering at Syracuse University before joining the faculty at the University of Rochester in 2007, where she serves as professor in three departments—biomedical engineering, neurobiology and anatomy, and electrical and computer engineering.

    Laurel Carney Awarded the 2015 William and Christine Hartmann Prize in Auditory Neuroscience

    Laurel Carney, Ph.D.

    Laurel H. Carney has been awarded the William and Christine Hartmann Prize in Auditory Neuroscience by the Acoustical Society of America (ASA). The award was presented at the 169th meeting of the ASA on 20 May 2015 in Pittsburgh, Pennsylvania.

    The William and Christine Hartmann Prize in Auditory Neuroscience was established in 2011 through a generous donation by Bill and Chris Hartmann to the Acoustical Society of America to recognize and honor research that links auditory physiology with auditory perception or behavior in humans or other animals.

    The Acoustical Society of America provides an important scientific home for researchers pursuing questions related to sound and hearing. This group has positively shaped many of our careers, especially by providing access to an incredible group of mentors and role models. Receiving an award created by Bill and Christine Hartmann, two of my own role models, is truly a great honor. This award presents a challenge for me to emulate their life of discovery, presentation, publication, service, and education throughout the world, said Carney.

    The goal of Dr. Carney's research program is to understand how the brain hears. The initial response of brain cells to sound is a complicated pattern of electrical pulses, a pattern that is modified and interpreted by millions of cells in many parts of the brain. Studies of physiology, human hearing, and computer models are combined to understand how this process works in listeners with normal hearing, so that an answer can be found to the question: How is the brain so good at hearing in noisy environments? Another goal is to understand why only relatively small amounts of hearing loss cause significant problems. Why does background noise (such as that in a busy restaurant) become so problematic for people with hearing loss? Answers to both of these questions will lead to better strategies for aiding listeners with hearing loss.

    $10 Million Grant Funds Center to Study OCD at UR School of Medicine and Dentistry

    Suzanne Haber, Ph.D.

    Suzanne Haber leads a research team to investigate OCD. She says the disease is characterized by intrusive, ruminating thoughts (obsessions), and impulses to carry out repetitive behaviors (compulsions), despite the awareness by most patients that these behaviors don't make sense.

    The goal of a new $10 million grant awarded to the scientists is to improve our understanding of the brain networks that play a central role in obsessive-compulsive disorder (OCD). Together with leading mental health researchers at four other institutions in the U.S., they will pinpoint specific abnormalities within the brain circuits that are associated with the disease and use this information to guide new treatment options for the three million-plus Americans who live with the disorder.

    The five-year grant from the National Institute of Mental Health (NIMH) establishes a new Silvio O. Conte Center for Basic and Translational Mental Health Research at the University of Rochester. Conte Centers are designed to bring scientists with diverse but complimentary backgrounds together to improve the diagnosis and treatment of mental health disorders.

    Mouse Model Helps Researchers Target Deadly Brain Disease

    At upper left, a healthy astrocyte (a supportive brain cell) is shown in blue between green sheaths of myelin, which are produced by oligodendrocytes, the tentacled objects also seen in green.In individuals suffering from Progressive multifocal leukoencephalopathy, JC viruses (red particles) first infect the astrocyte (upper right) and mutate, eventually causing the astrocyte to explode (bottom image). The viruses then infect the oligodendrocytes.

    When University researchers Steven Goldman and Maiken Nedergaard created a mouse model whose brains consisted of both animal neurons and human glia cells, their study initially focused on findings that the human cells essentially made the mice smarter.

    However, they also created a powerful new platform for researchers to study human glial cells in experimental animals. And that is providing new insights into Progressive multifocal leukoencephalopathy (PML).

    The study, out today in the journal Cell Stem Cell, suggests that the evolution of a subset of glia called astrocytes – which are larger and more complex in humans than other species – may have been one of the key events that led to the higher cognitive functions that distinguish us from other species.

    NBA Faculty Candidate: Krishnan Padmanabhan, PhD

    Krishnan Padmanabhan, PhD

    Faculty candidate Dr. Padmanabhan, Junior Fellow Crick-Jacobs Center for Theoretical and Computational Biolgy The Salk Institute of Biological Studies, will present the talk The Role of Diversity in the Neural Computations Monday, February 23rd at 2:00pm in K-307 (3-6408)


    A key question in neuroscience is to understand how neuronal circuits process sensory information and generate behaviors in response to that information. Consider the sense of smell for instance. In a single sniff, mammals can synthesize data about dozens of volitile chemical compounds to create a singular unified perception, like the smell of coffee. In the olfactory system of mice, feedforward projections from the principle cells of the main olfactory bulb relay information about these odors directly to cortical regions as an early step toward forming a sensory percept. Feedback projections from these cortical areas back to early olfactory structures dynamically impact the way incoming odor information is processed based on such features as experience, memory and brain state. How these two computations are done, and how the olfactory system uses these computations to generate behavior remain open questions.

    In my talk, I will discuss our recent work tackling 2 aspects of this process.

    1. How the biophysical properties of neurons improves information transmission in the feedforward direction.
    2. How the anatomy of connections from the higher processing areas may reveal key computational principles about sensory processing.
