2026 Nobel Prize in Physiology Awarded for Optogenetics Breakthrough
Nobel Prize in Physiology or Medicine 2026 awarded for breakthrough in optogenetics
The 2026 Nobel Prize in Physiology or Medicine has been awarded to Peter Hegemann, Georg Nagel, and Karl Deisseroth for their pioneering work in optogenetics, a technique using light to control nerve cells and study brain function.
Hegemann and Nagel discovered channelrhodopsin, a light-sensitive protein from single-celled algae that opens ion channels when exposed to blue light. Deisseroth later demonstrated the technique's application in living organisms, showing in 2007 that blue light could trigger nerve signals in mouse brains.
The Nobel Committee noted that optogenetics has transformed neuroscience by enabling researchers to investigate neural circuits underlying specific memories, emotions, and behaviors. The technique is being explored in clinical research, including potential applications to restore sight in people with visual impairments.
