Nobel-Winning Scientist Explains How He Developed Optogenetics

Karl Deisseroth, a neuroscientist at Stanford University, has explained how he made his Nobel-winning discovery of optogenetics, a technique that allows researchers to control the activity of neurons with light. Deisseroth's work involved inserting a gene from a single-celled algae into rat cells, which responded to light by activating. This breakthrough led to the development of optogenetics, which has been used to control living mice and is now being explored for its potential to restore sight in people with visual impairment.
