Julie Schnapf, Ph.D. from University California San Francisco is delivering a seminar this Wednesday, September 12, 2012 at the Moran Eye Center auditorium on the first floor.  Julie will be talking about Photoreceptor Networks and Color.

Abstract:  Photoreceptors are more than just photon transduction machines.  They also communicate with each other, forming interactive electrical networks that increase visual sensitivity and create color-opponency.  These network interactions help explain some puzzling observations about color perception.
