Professor Laurel Carney Receives a 2010 R01 Grant
Biomedical Engineering and Neurobiology & Anatomy Professor Laurel Carney has received funding for her 2010 R01 grant entitled:
Developing and Testing Models for the Auditory System with & without Hearing Loss. This study involves testing listeners with both normal hearing and hearing loss. The project focusses on the development of computational models that will assist in the testing of signal processing strategies for hearing aids.
She also received a renewal for five years of support from the NIH-NIDCD to study Auditory Processing of Complex Sounds; this renewal extends this research program to 20 consecutive years of NIH funding. Her research has resulted in better understanding of the physiological response to sound in the healthy auditory system, and may contribute to the improvement of hearing aids for those with hearing loss.

The Majewska Lab's current research on learning and memory has been featured in the current issue of Nature Highlights. The research details immune cells called microglia help to protect the brain after an injury. They may also be involved in pruning the connections, or synapses, between neurons — a key process in learning and memory formation.
Using electron microscopy, Marie-Ève Tremblay, Rebecca Lowery and Ania Majewska at the University of Rochester in New York imaged mouse brain slices and reconstructed the interactions between microglia and synapses in three dimensions. Most of the microglia were directly adjacent to the synapses, and in particular to dendritic spines — neuronal structures — that were small and were often pruned away later on.

Immune cells known as microglia, long thought to be activated in the brain only when fighting infection or injury, are constantly active and likely play a central role in one of the most basic, central phenomena in the brain – the creation and elimination of synapses.
The finding, reported in the Nov. 2 issue of PloS Biology, catapults the humble microglia cell from its well-recognized duty of protecting the brain to direct involvement in creating the cellular networks at the core of brain behavior.
When scientists talk about microglia, the talk is almost always about disease. Our work suggests that microglia may actively contribute to learning and memory in the healthy brain, which is something that no one expected,said Ania Majewska, Ph.D., assistant professor in the Department of Neurobiology & Anatomy who led the work.
The group's paper, co-authored by post-doctoral associate, Marie-Ève Tremblay, Ph.D., is a remarkably detailed look at how brain cells interact with each other and react to their environment swiftly, reaching out constantly to form new links or abolish connections.

The University of Rochester Medical Center has received $15 million in federal bioterrorism funding that allows investigators to build on several discoveries made during the past five years to improve the ability to treat radiation injuries, especially from an act of terrorism.
URMC was awarded an initial grant of $21 million in 2005 to become part of a national research network, Centers for Medical Countermeasures Against Radiation. The centers were charged with researching how best to respond to a dirty bomb or other radiological or nuclear attack.
A second, $15 million, five-year award, received this month from the National Institutes of Health/National Institute of Allergy and Infectious Disease, will allow URMC researchers to focus on testing known drugs and experimental agents and their ability to ward off systemic radiation injury that affects the lungs, brain, skin and bone marrow.

Earlier this month, the Center for Visual Science (CVS) held its 27th symposium. The theme of this year's symposium was
Photons and Neuronsand it brought together scientists who develop and use optical imaging methods from all over the world.
Optical imaging promises to revolutionize neuroscience by offering minimally-invasive, direct recording of neural activity at single cell resolution in the intact working brain. Optical imaging of neural activity, however, has yet to deliver the ultimate prize of recording the activity of many individual neurons in real time throughout the depth of a brain structure such as the cerebral cortex. Achieving such a goal will require the coordinated effort of experts from disparate backgrounds, including neuroscientists, optical engineers, biochemists and molecular biologists.
The symposium brought together this diverse group of scientists and provided a platform for discussion of the latest developments in optical imaging of neuronal function. Discussions were long and lively and allowed the exchange of ideas, identification of pressing neurobiological questions, discussion of current limitations, and developing of ideas for possible solutions. The symposium was supported by the National Eye Institute (R13EY020691) and the Center for Visual Science, and was co-organized by David Williams, Ania Majewska and Tony Movshon (NYU).

Youngsun Cho is Awarded NRSA Individual Training Grant
Youngsun Cho, a first year MSTP student in the Fudge Lab was recently awarded a Ruth Kirschstein National Research Service Award (F30) for three years of training. Youngsun's proposed studies involve examining circuitry that may underlie modulation of approach behavior in anxious adolescents. She will first detail connections between specific regions of the prefrontal cortex the amygdala in animals, based on her work in Rochester. This data will then be used to design studies investigating functional connectivities between these regions in anxious adolescents. The latter studies are being conducted in partnership with Dr. Monique Ernst at the NIMH intramural program.

Anne Luebke, Ph.D., Associate Professor in Neurobiology & Anatomy and Biomedical Engineeering, and Loisa Bennetto, Ph.D., Chair of the Department of Clinical and Social Psychology, have been awarded a collaborative pilot grant to study whether physiological-based biomarkers of cochlear efferent strength will be impaired in the autism spectrum disorder (ASD) population.
The specific aim of the project is to determine efferent feedback strength in children and adolescents with ASD when compared with typical controls (age, gender, and IQ matched). The project will build on existing measures of MOC strength using two different otoacoustic emission-based tests with short and sustained binaural broadband suppression to obtain maximal efferent feedback strength in both ears of all participants.

Scientists have taken another important step toward understanding just how sticking needles into the body can ease pain.
In a paper published online May 30 in Nature Neuroscience, a team at the University of Rochester Medical Center identifies the molecule adenosine as a central player in parlaying some of the effects of acupuncture in the body. Building on that knowledge, scientists were able to triple the beneficial effects of acupuncture in mice by adding a medication approved to treat leukemia in people.
The new findings add to the scientific heft underlying acupuncture, said neuroscientist Maiken Nedergaard, M.D., D.M.Sc., who led the research. Her team is presenting the work this week at a scientific meeting, Purines 2010, in Barcelona, Spain.

Dr. Patricia M. White Joins NBA Faculty
It is a pleasure to welcome Patricia M. White, PhD to our faculty as Assistant Professor of Neurobiology & Anatomy and Otolaryngology. Her work fits solidly within a key research initiative in Neurobiology and Anatomy that we refer to as sensory-motor neuromedicine. Pat carries an important new area to the University in sensory regeneration of the inner ear, or hair-cell regeneration. This promising area of translational research targets cultured stem/progenitor cells to restore hearing through implantation into damaged cochlea and/or vestibule, or alternatively, exploits existing supporting cells to reenter the cell cycle, effectively become progenitors once again, and ultimately restore sensory structure and function.
