The first steps in vision: cell types, circuits, and repair

Dysfunction of the key sense of vision, leading to visual handicap or blindness, has a crucial effect on day‐to‐day life. In this commentary, I will summarize the work in my laboratory that is focused on a basic understanding of visual processing and the use of this information to understand disease mechanism and to develop correcting therapies. We are beginning to understand how cell types of the visual system interact in local circuits and compute visual information. This has brought insight into mechanisms of cell‐type‐specific diseases and has allowed us to design new therapies for restoring vision in genetic forms of blindness.
