Retinal Types and Circuits

The retina is not a video camera; it is the world’s most advanced image processing machine, refined over hundreds of millions of years of evolution. My lab seeks to understand the computations performed by retinal circuits. We are working toward a comprehensive classification of retinal ganglion cells, the output cells of the retina, that includes physiology, morphology and gene expression patterns for each cell type. Our catalog of mouse retinal ganglion cells is online at

From this “parts list” we work our way into the circuits of the retina to answer the “how” questions about the synaptic and circuit mechanisms of retinal computation.
