E.J. Chichilnisky, Ph.D.
E.J. Chichilnisky, Ph.D., from the School of Medicine & Hansen Experimental Physics Laboratory at Stanford University will deliver the 2014 Vision Research Lecture on Tuesday, October 14, at 11:00 a.m. in the Lipsett Amphitheater, Building 10. His talk is titled High-resolution Electrical Stimulation of the Retina for Epiretinal Prosthesis Design.
The retina contains at least 1 million retinal ganglion cells, and what we see depends on activating the right ones at the right time. Dr. Chichilnisky theorizes that prosthetic devices can be designed to stimulate these cells in the precise spatial and temporal patterns needed for natural vision. He will show that low-level stimulation delivered through small electrodes can reliably activate single retinal ganglion cells with high temporal precision and without activating other nearby cells. He will also show that this precision can extend to small groups of cells. He will discuss other challenges and the approaches his lab is taking to address them.
The Sayer Vision Research Fund was established in 2006 at the Foundation for the National Institutes of Health by Jane M. Sayer, Ph.D., a research scientist with the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), to honor her family and the memory of her parents, Winthrop and Laura Sayer. The fund incorporates Dr. Sayer’s desire to contribute to groundbreaking medical research at NIH while specifically raising the profile of vision research. In partnership with the NEI, the fund supports the Sayer Vision Research Lecture Series, given by a scientist of national or international prominence in a discipline with relevance to vision research. From time to time, the fund also supports an award to a promising young NIH investigator in eye research, of which Dr. Li is the first recipient.
