The 2026 Nobel Prize in Physiology or Medicine was awarded to Peter Hegemann, Georg Nagel, and Karl Deisseroth for their pioneering discoveries concerning light-gated ion channels and optogenetics.
Optogenetics is a technique that allows scientists to control the activity of specific brain nerves using light. By using light-sensitive proteins like channelrhodopsin, researchers can turn specific nerve cells on or off to observe how they affect the body and behavior.
Peter Hegemann and Georg Nagel discovered the protein channelrhodopsin while studying how single-celled algae swim toward light, finding that blue light opens a channel to generate electrical signals. Karl Deisseroth later applied this protein to nerve cells, demonstrating that neurons could be activated via light and eventually utilizing the technique in living mice.
