| Leonardo Belluscio, Ph.D., Investigator |

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 explore the development of the olfactory system with emphasis on neural plasticity associated with neonatal learning.

Research Interests:
Olfactory sensory neurons, which reside in the olfactory epithelium, detect odors in the outside world and transmit this information directly to the output neurons of the olfactory bulb. Within the olfactory bulb a large population of inhibitory interneurons extensively modulates this information before it is relayed on to the olfactory cortex. This information processing is thought to play a critical role in the plasticity underlying olfactory learning. Since the mammalian olfactory system continues to develop for several weeks postnatally, this defined period of heightened plasticity provides a perfect window of opportunity to study the interplay between development and learning.
Our research focuses on elucidating the synaptic circuitry that is established during initial bulb development, and defining the factors that cause its reorganization during neonatal learning. We use a multi-dimensional approach that combines molecular biology, transgenics, optical imaging and electrophysiology to perform both in-vivo and in-vitro studies in genetically engineered mice.
