Nobel Prize in Medicine recognizes trio for discoveries in optogenetics
American Karl Deisseroth and Germans Peter Hegemann and Georg Nagel were recognized with the 2026 Nobel Prize in Physiology or Medicine
TL;DR
- Karl Deisseroth (USA), Peter Hegemann (Germany), and Georg Nagel (Germany) won the 2026 Nobel Prize in Physiology or Medicine.
- Their research focuses on optogenetics, a technique that uses light to control nerve cells.
- Hegemann and Nagel discovered channelrhodopsin, a light-sensitive protein in algae.
- Deisseroth developed this protein into a light-controlled switch for nerve cells, enabling the activation of neural signals.
- Optogenetics has revolutionized neuroscience, offering insights into brain circuits controlling memory, emotion, and behavior.
- The technique is being explored for clinical applications, such as restoring vision in visually impaired individuals.
- The Nobel Prize money for Medicine increased by 9% to 12 million Swedish kronor for 2026.
