Briefings

American Karl Deisseroth and German scientists Peter Hegemann and Georg Nagel received the 2026 Nobel Prize in Physiology or Medicine for pioneering optogenetics, a technique enabling precise control of individual nerve cells using light. This breakthrough allows researchers to activate or inhibit specific brain neurons with light, opening new avenues for understanding neurological disorders and developing treatments for conditions like epilepsy and depression. The award was presented on Monday following the announcement of the prize distribution.

Key points

• Karl Deisseroth, Peter Hegemann, and Georg Nagel won the 2026 Nobel Prize in Physiology or Medicine for developing optogenetics, a technique that uses light to control individual nerve cells in the brain.
• The Nobel Prize was awarded on Monday for the development of optogenetics, which allows researchers to activate or inhibit specific brain neurons with light, facilitating new research into neurological disorders.

Context and limitations
