NGP Student Article Published in the bioRxiv
Monday, August 19, 2019
Abstract: Perioperative neurocognitive disorders (PND), including delirium and postoperative cognitive dysfunction, are serious complications that afflict up to 50% of surgical patients and for which there are no disease-modifying therapeutic options. Here, we test whether prophylactic treatment with the broad spectrum mixed-lineage kinase 3 inhibitor URMC-099 prevents surgery-induced neuroinflammation and cognitive impairment in a translational model orthopedic surgery-induced PND. We used a combination of two-photon scanning laser microscopy and CLARITY with light-sheet microscopy to define surgery-induced changes in microglial morphology and dynamics. Orthopedic surgery induced microglial activation in the hippocampus and cortex that accompanied impairments in episodic memory. URMC-099 prophylaxis prevented these neuropathological sequelae without impacting bone fracture healing. Together, these findings provide compelling evidence for the advancement of URMC-099 as a therapeutic option for PND.Read More: NGP Student Article Published in the bioRxiv

Friday, May 3, 2019
Dr. Gary Paige is the 2019 recipient of the Peter Shrager Award, which recognizes exceptional service to the Rochester neuroscience community. The award was established in 2017 to honor Dr. Peter Shrager, professor in the Department of Neuroscience, for his commitment to the education and research mission of the neuroscience enterprise at the University over his last 40 years as a faculty member. Dr. Gary Paige served as the chair of Neurobiology and Anatomy for more than ten years and was a tireless advocate for neuroscience faculty and students. In this role, he built a very open neuroscience community, expanding the department through secondary appointments and encouraging faculty be active members of the neuroscience community at large. He was a strong supporter of graduate and medical education, using creative solutions to forge collaborative and interdisciplinary research that integrated basic, translational and clinical approaches. Since stepping down as chair, he has continued to be influential in creative ways by marrying his two loves—art and neuroscience—in the Arts in Mind project, an educational experience for UR students and faculty. Dr. John Foxe presented the award at the annual neuroscience retreat on Friday, April 12.
NGP Alum, Aleta Steevens, awarded Doty prize
Friday, May 3, 2019
Aleta Steevens, recent doctoral graduate from the Kiernan lab, received the Robert Doty prize for the 2019 outstanding dissertation in neuroscience. The Doty prize is named in the honor of longtime faculty member Robert Doty, who made great contributions to neuroscience research at the University of Rochester and nationally. It is awarded on the basis of the impact and importance of research, novelty of experimental design, independence and creativity of the student and research implications and relevance for neuroscience. Aleta’s thesis entitled “The Dynamic Role of SOX2 in Mammalian Inner Ear Development,” which she successfully defended on April 16, 2018, embodied all these characteristics. Aleta was also awarded an NIH predoctoral fellowship, and her work has resulted in two first-author publications. Beyond her research, Aleta was exceptionally active and successful in teaching. She served as a TA in the course Biology of Mental Disorders, and won the Edward Peck Curtis teaching award in 2016.

Handy Gelbard Honored for Pediatric HIV/AIDS Research
Wednesday, April 17, 2019
Handy Gelbard, M.D., Ph.D., professor and director of the Center for Neurotherapeutics Discovery at URMC, is the 2019-2020 recipient of the Herman and Gertrude Silver Award, which honors individuals who have made significant contributions in the field of pediatric HIV and AIDS. The award is given by the Children’s Hospital of Philadelphia (CHOP) and the Department of Pediatrics of the Perelman School of Medicine at the University of Pennsylvania. Past award winners include a Nobel laureate and HIV investigators from leading academic institutions, the National Institutes of Health (including the current directors of the Office of AIDS Research and the National Institute of Allergy and Infectious Diseases), and the Centers for Disease Control and Prevention.
For the past 10 years Gelbard’s lab has been developing a compound called URMC-099, which dampens inflammation and has shown promise in reversing the neurological problems associated with HIV. Children with HIV who are taking combination antiretroviral therapies are extremely vulnerable to inflammation; the developing nervous system is of particular concern, as inflammation in the brain can lead to major cognitive problems.
The possibility of a new class of therapies that reduces the burden of neuroinflammation and supports normal synaptic architecture (the basis for learning and memory) offers considerable hope for children that are saddled with the unwanted burden of HIV, despite effective control of the virus.
Gelbard believes the path forward for URMC-099 as an adjunct agent for children living with HIV and neurologic disease will likely involve combination therapy with next generation antiretroviral agents. This is a priority in resource-limited settings such as Africa, and Gelbard is working with David Bearden, M.D., assistant professor in the division of Child Neurology at URMC to help advance uses for URMC-099 in pediatric patients there. Bearden’s work is supported by a National Institute of Neurological Disorders and Stroke grant to Gretchen Birbeck, M.D., M.P.H., professor of Neurology and Michael Potchen, M.D., professor of Imaging Sciences. The work is also supported by the University of Rochester Center for AIDS Research.
Gelbard will receive the Silver Award in November during a two-day symposium at CHOP. He will present pediatric grand rounds describing his progress in inventing the class of compounds spearheaded by URMC-099 and its role in treating pediatric and adult HIV infection and its complications. He’ll also give a seminar on current and future developments related to URMC-099 to attendees from multiple medical and scientific institutions in Philadelphia.

University of Rochester Investigators Attend the 2019 ARO MidWinter Meeting
Friday, February 22, 2019
The University of Rochester was well-represented at the Association for Research in Otolaryngology (ARO)’s 42nd Annual MidWinter Meeting. This prestigious academic conference brings together researchers and clinicians from around the world to present their work on diverse topics in the fields of Otolaryngology and Auditory Neuroscience. Several UR Neuroscience Department investigators were on hand to share their findings with over 1500 colleagues at Baltimore’s Marriott Waterfront from February 9th to the 13th.
Genetic signaling pathways underlying cochlear development, damage, and recovery were highlighted by the White and Kiernan labs. Patricia White’s lab presented their work on hearing recovery within adult mouse cochlea after noise damage. Jingyuan Zhang, a postdoctoral candidate, proposed activation of the ErbB signaling pathway as a means to promote hearing recovery and regeneration in the inner ear. Holly Beaulac, a Neuroscience graduate student, discussed how the transcription factor FOXO3 may play a role in cochlear inflammatory regulation.
Felicia Gilels, a CBD graduate student in Amy Kiernan’s lab, examined the role of the Notch signaling pathway in cochlear maturation. Specifically, she presented work showing that loss of JAG1 leads to auditory neuropathy, caused by stereocilia defects in the inner hair cells. These results indicate that hair cell regeneration by manipulating Notch should proceed cautiously, as clearly the postnatal roles of Notch are not fully understood.
Ross Maddox’s lab investigates how multiple sensory stimuli can be processed and how distractions including noise can affect the efficacy of such input. Lab members Madeline Cappelloni, a BME graduate student, and undergraduate Sara Fiscella explained the ways in which coherence of visual and auditory stimuli may be disrupted during task manipulation.

Yingxuan Wang, a BME graduate student in Ken Henry’s lab, described their investigation into inferior colliculus neural responses when birds attempt to detect tones in noise. Laurel Carney and her students showcased their findings across five posters. BME graduate student Langchen (Elsie) Fan provided physiological model simulations of comodulation masking release, or the ways tones can become easier to hear in noise, for individuals with and without hearing loss. Paul Mitchell, a BME graduate student, helped characterize midbrain selectivity for direction and velocity during sound presentation.
In the realm of vestibular research, J. Chris Holt gave a podium talk on establishing the pharmacological tools to investigate the physiological role of mammalian vestibular efferents, the nerves that project from the central nervous system to the vestibular sensory cells. Benjamin Crane and undergraduate Raul Rodriquez discussed the adaptation of heading perception which is important for ambulation, navigation, and spatial orientation. Daniel Martin, a medical resident in the Crane lab, presented his use of a novel virtual reality technique to adapt heading perception in cases of unilateral vestibular loss.
Art and science intersected in the neuroscience of music presentations. Using EEG, Nathaniel Zuk, a postdoctoral candidate in Edmund Lalor’s lab, revealed specialized high-level processing of both speech and music. Anne Luebke featured three posters focused on how musical training can influence one’s ability to discriminate between tones in noise. She also highlighted ongoing collaborative work with Loisa Bennetto and Paul Allen on how musical aptitude can predict auditory filtering in young adults and children with Autism Spectrum Disorder.
ARO’s 2019 MidWinter Meeting provided an impressive showcase of promising areas of research in otolaryngology and auditory neuroscience. We expect UR’s scientific impact to continue at next year’s meeting in San Jose, California!

Study suggests how high blood pressure might contribute to Alzheimer’s
Monday, January 28, 2019
The brain’s system for removing waste is driven primarily by the pulsations of adjoining arteries, University of Rochester neuroscientists and mechanical engineers report in a new study. They also show that changes in the pulsations caused by high blood pressure slow the removal of waste, reducing its efficiency.
This might explain the association between high blood pressure and Alzheimer’ disease, the researchers say. Alzheimer’s, the most common cause of dementia among older adults, is characterized by abnormal clumps and tangled bundles of fibers in the brain.
The study, reported in Nature Communications, builds upon groundbreaking discoveries about the brain’s waste removal system by Maiken Nedergaard, co-director of the University’s Center for Translational Neuromedicine. Nedergaard and her colleagues were the first to describe how cerebrospinal fluid is pumped into brain tissue and flushes away waste. Subsequent research by her team has shown that this glymphatic waste removal system is more active while we sleep and can be damaged by stroke and trauma.
This latest research shows “in much greater depth and much greater precision than before” how the glymphatic system functions in the perivascular spaces that surround arteries in the outer brain membrane, says Douglas Kelley, an assistant professor of mechanical engineering and an expert in fluid dynamics. His lab is collaborating with Nedergaard’s team as part of a $3.2 million National Institute on Aging grant.
For this study, Humberto Mestre, a PhD student in Nedergaard’s lab, injected minute particles in the cerebrospinal fluid of mice, and then used two-photon microscopy to create videos showing the particles as they moved through the perivascular spaces.Read More: Study suggests how high blood pressure might contribute to Alzheimer’s
In The News: UR study on brain waves may allow doctors to diagnose autism earlier
Friday, January 25, 2019
The following is an except of an article by Josh Navarro that originally appeared on WROC/RochesterFirst.com:
A new study to help understand brain waves in children with autism is underway right now at the University of Rochester Medical Center. Their aim is to foster earlier detection and foster better therapies in the future.
Children with autism respond differently when they hear a sound such as music or see an illustration. Honing in the difference in brain waves between autistic children and children who do not have autism, is part of a new study at Del Monte Institute for Neuroscience at URMC.
“If you can provide a biological marker that could be reproduced earlier in a child's development, then that therapy can start earlier, the better outlook for that particular child,” said Dr. Evan Myers, Postdoctoral Fellow at the Cognitive Neurophysiology Lab in the University of Rochester Del Monte Institute for Neuroscience.
Researchers will place a electroencephalography cap and have kids observe different images on a computer screen. The findings will determine the next step through clinical trials with the goal of diagnosing a child with autism a lot sooner.

Dr. Kuan Hong Wang comes to the University of Rochester
Monday, January 21, 2019
We are pleased to welcome Dr. Wang to the University of Rochester Medical Center, the Department of Neuroscience and the Del Monte Institute for Neuroscience from the NIH.
Dr. Wang comes to us as the former chief of the Unit on Neural Circuits and Adaptive Behaviors at the National Institute of Mental Health. Dr. Wang received his B.A. in Biochemical Sciences from Harvard College and his Ph.D. from the University of California at San Francisco, where he studied the molecular regulators of sensory axon growth and branching during development with Marc Tessier-Lavigne. Dr. Wang obtained postdoctoral training with Susumu Tonegawa at the Massachusetts Institute of Technology, where he examined the ways in which cortical neurons respond to an animal’s experience by directly visualizing the molecular activity of a given set of neurons over several days in the live animal. With this approach, he revealed a physiological function of neural activity regulated gene Arc in sharpening stimulus-specific responses in visual cortex.
