The 2026 Nobel Prize in Physiology or Medicine was jointly awarded to Karl Deisseroth, Peter Hegemann, and Georg Nagel for discovering light-gated ion channels and developing optogenetics.
Optogenetics is a technique that lets researchers control individual nerve cells in a living brain using light. Peter Hegemann and Nagel discovered channelrhodopsin, a light-responsive protein, and Deisseroth later used its gene in rat and mouse nerve cells to trigger signals with blue light.
The technique allows scientists to study how specific nerve cells influence memory, fear, movement, and mood, helping research into conditions like Parkinson’s disease, depression, and addiction. Early clinical work is also exploring its potential to help restore partial vision.
