Research Topics

My Laboratory conducts research to understand the principles and mechanisms that underlie neural plasticity and regeneration in the brain. Using the mammalian olfactory system as a model the laboratory focuses on four main goals: (1) identification of neural circuits within the olfactory system that exhibit functional plasticity; (2) determining the molecular and functional mechanisms that govern olfactory based plasticity; (3) understanding the relationship between plasticity and the capacity for repair of olfactory circuits; and (4) establishing the role of sensory induced activity on the restoration of neural circuits. Our research is multidisciplinary including biochemistry, molecular biology and electrophysiology as well as in vivo imaging, optogenetic and behavioral techniques all combined with genetically engineered mice. Given the connection between olfactory dysfunction and neurological disease such as Alzheimer's disease and Parkinson's disease, this work also has a strong translational focus.

Biography

Dr. Belluscio received his B.S. from Manhattan College and his Ph.D. from Columbia University where he studied the molecular and cellular organization of the mammalian olfactory system with Richard Axel. He then went on to do post-doctoral training with Larry Katz at Duke University, where he investigated the functional and anatomical organization of the olfactory bulb using various imaging techniques. Dr. Belluscio joined NINDS as an investigator in 2002. His laboratory now combines molecular and functional techniques to study olfactory neural plasticity associated with circuit development and its repair following disruption.
