Scientists Use Light To Control Brain With Flick Of A SwitchJune 28th, 2012 | Posted by in What Is Light Therapy Information
Scientists have developed a way of using pulses of light to turn the brain cells that control our everyday actions and thoughts on or off at will. The researchers have conducted tests in monkeys using light to send them to sleep. First, cells in the brain itself must be genetically altered so they react to light. Such genetic modification of human cells is still an emerging science and the long-term effects are still largely unknown. Dr Edward Boyden, a biological engineer at the Massachusetts Institute of Technology says, "As a therapy, this could help tackle diseases which are difficult or unlikely to be treated by other means." When light hits these altered brain cells, they turn on or off, depending on the gene that has been inserted. Scientists states that this is one of the most exciting areas of science to have emerged recently.
