The 2026 Nobel Prize in Physiology or Medicine was awarded to American Karl Deisseroth and Germans Peter Hegemann and Georg Nagel for their groundbreaking contributions to optogenetics. The announcement was made on October 5, 2026, during a press conference at the Nobel Forum in Stockholm.
Revolutionizing Neuroscience with Light
This method is now being used in laboratories around the world to reveal the brain’s mysteries.
Thomas Perlmann, Secretary-General of the Nobel Assembly
- Optogenetics allows precise control of nerve cell activity using light.
- Current clinical trials aim to restore vision in patients with retinitis pigmentosa through this technique.
The Nobel Assembly praised the laureates for their discoveries regarding light-gated ion channels, essential in understanding brain functionality. Their work enables scientists to manipulate individual nerve cells in living organisms, offering new insights into neural processes.
In particular, optogenetics is making strides in restoring vision and enhancing cochlear implants. The technique involves inserting a light-sensitive protein into retinal cells to generate electrical impulses in response to light.
Deisseroth, Hegemann, and Nagel expressed their joy at receiving the award together, emphasizing the collaborative nature of their research. Perlmann noted their mutual delight in sharing this honor.
This year's award marks the continuation of a long-standing tradition of recognizing transformative contributions to science. The Nobel Prize in Medicine has historically acknowledged key discoveries, including the work on penicillin and blood group classification.
The total prize amount for the laureates is 12 million Swedish crowns (approximately $1.2 million). The Nobel ceremonies culminate on December 10, which commemorates the anniversary of Alfred Nobel's death.
