معرفی
Robert G. Smith, Ph.D., is an Adjunct Associate Professor in the Department of Neuroscience at the Perelman School of Medicine, University of Pennsylvania. His research laboratory employs electrophysiological recordings and biophysically realistic computer simulations to investigate neural signal processing in retinal circuits.
Education:
- B.S. in Biology, Haverford College, 1971
- University of Pennsylvania, College of General Studies, 1982
- Ph.D. in Neuroscience, University of Pennsylvania, 1989
Research Focus: Dr. Smith's work centers on modeling how neuronal structure, biophysical properties, and synaptic connections influence circuit function in the retina. His laboratory constructs detailed simulations of four key systems: cone-to-horizontal cell networks, rod photoreceptor pathways during dark adaptation, brisk-transient ganglion cells, and direction-selective circuits involving starburst amacrine cells. By incorporating noise properties of membrane channels and synaptic vesicle release, his models bridge physiological data with functional interpretations of neural components.
Publication Trends: Recent work (2019-2023) demonstrates sustained focus on direction selectivity mechanisms across species, with emerging themes in glycinergic/cholinergic feedback systems, disinhibitory microcircuits, and computational approaches for neuroprosthetics. His primate and mouse retina studies consistently integrate experimental validation with biophysical modeling.
Laboratory: Maintains an active research facility with dedicated web resources for the Neuron-C simulation language, emphasizing collaborative computational neuroscience approaches to retinal processing.
