We study signal processing mechanisms across the entire neural circuit of the retina. We use a battery of techniques relying on genetically modified mice, molecularly tailored artificial visual pigment molecules, and cutting-edge electrophysiological recording techniques. We seek to understand the functional implications of retinal signal processing mechanisms by correlating our results with the output of the entire visual system measured in mouse behavioral experiments and human psychophysics.
