In 2004, scientists, including author Edward S. Boyden, Ph.D., found that the neural expression of a protein, channelrhodopsin-2 (ChR2), allowed light to activate or silence brain cells. This technology, now known as optogenetics, is helping scientists determine the functions of specific neurons in the brain, and could play a significant role in treating medical issues as diverse as sleep disorders and vision impairment.
