How the Brain Works, Curing Blindness & How to Navigate a Career Path | Dr. E.J. Chichilnisky

About this video

Neuroscientist Dr. E.J. Chichilnisky explains how the retina encodes the visual world and how that knowledge could restore sight. He argues current retinal implants treat the retina like a camera’s grid of pixels, producing only crude vision such as sensing a bright doorway, because they ignore the roughly 20 or more distinct retinal cell types that each send different information to the brain, which he likens to sections of an orchestra playing different scores. Chichilnisky says building implants that respect that code is the next phase of his career. The conversation also covers his winding career path, including leaving and returning to graduate study and years spent dancing, as a model for navigating a professional life.

• Dr. Chichilnisky argues current retinal implants fail to restore rich vision because they ignore those distinct cell types.
• Dr. Chichilnisky compares retinal cell types to orchestra sections each playing a different score.
• Dr. Chichilnisky describes how wandering, including time spent dancing, shaped his career choices.
