Using light to probe the brain's self-repair after a stroke

A revolutionary new technique is allowing Canadian researchers to map, with exquisite precision, how the brain repairs itself after a stroke.
Optogenetics gives neuroscientists the ability to control brain circuits in laboratory animals with lasers, to turn cells on or off with a flash of light. It offers a new way to probe what different parts of the brain do and could lead to new treatments for a variety of neurological conditions.
