Greg D. Field
I am a postdoctoral researcher at the Salk Institute in La Jolla California. My primary interest is in how the external world is encoded by our sensory systems. In particular, I study the retina, the light sensitive neural tissue at the back of the eye. I am working to understand how elements of the visual world, such as color and motion, are encoded by the electrical impulses produced by retinal ganglion cells, the carriers of signals from the retina to the brain. I am also interested in how these coding properties change as our visual system adapts from bright to dim conditions such as daytime and nighttime.
