Optogenetics: Using Light to Control the Brain by Edward S. Boyden, Ph.D
Optogenetics: Using Light to Control the Brain By Edward S. Boyden, Ph.D. Courtesy of the MIT McGovern Institute, Julie Pryor, Charles Jennings, Sputnik Animation, and Ed Boyden. Editor’s note: The brain is densely packed with interconnected neurons, but until about six years ago, it was difficult for researchers to isolate neurons and neuron types to determine their individual roles in brain processes. In 2004 however, 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. Article available online at http://dana.org/news/cerebrum/detail.aspx?id=34614 1 The brain is an incredibly densely wired computational circuit, made out of an enormous number of interconnected cells called neurons, which compute using electrical signals. These neurons are heterogeneous, falling into many different classes that vary in their shapes, molecular compositions, wiring patterns, and the ways in which they change in disease states. It is difficult to analyze how these different classes of neurons work together in the intact brain to mediate the complex computations that support sensations, emotions, decisions, and movements—and how flaws in specific neuron classes result in brain disorders. Ideally, one would study the brain using a technology that would enable the control of the electrical activity of just one type of neuron, embedded within a neural circuit, in order to determine the role that that type of neuron plays in the computations and functions of the brain. -
