Michael B. Manookin

A retinal balancing act: crossover inhibition and NMDA receptors mediate visual sensitivity in parasol/M ganglion cells of the macaque monkey retina

When

June 9, 2011, 12:00 p.m. to 1:00 p.m.

Who

Michael B. Manookin

Ph.D. is a postdoctoral fellow in the Department of Structural Biology at University of Washington in Seattle, WA

Where

Fralin Biomedical Research Institute, R1059
2 Riverside Circle, Roanoke, VA 24016

Michael Manookin, a postdoctoral fellow in the laboratory of Dennis Dacey at the University of Washington in Seattle, will present his recent findings from the macaque monkey retina on the role of a particular class of retinal ganglion cells in contributing to visual system sensitivity. Manookin uses a combination of electrophysiological, pharmacological and cellular structural analysis in the primate retina to functionally analyze the mechanisms that mediate changes in visual responsiveness over a range of visual conditions.

Manookin is a recent recipient of a prestigious Helen Hay Whitney Foundation Fellowship award.
