Clinical curiosity met basic science, and a light-seeking alga helped earn the 2026 Nobel Prize in Physiology or Medicine.

Peter Hegemann, PhD and Georg Nagel, PhD discovered channelrhodopsin, the protein that lets the alga swim toward light. Karl Deisseroth, MD, PhD, a psychiatrist seeking better answers for his patients, turned it into a light switch for nerve cells.

The result is optogenetics, which lets scientists:

- Prove which brain circuits drive memories, feelings, and behaviors
- Study the circuits behind neurological and psychiatric disorders
- Pursue new ways to restore sight, with early trials showing partial success

Congratulations to all three Nobel laureates on opening a new era in neuroscience.

Karl Deisseroth, MD, PhD, winner of the Nobel Prize in Physiology or Medicine 2026, describes the science behind a study of intravitreal delivery of an AAV vector encoding a light-gated ion channel in 10 blind patients with advanced retinitis pigmentosa.

BREAKING NEWS
The Nobel Assembly at Karolinska Institutet has decided to award the 2026 Nobel Prize in Physiology or Medicine to Karl Deisseroth, Peter Hegemann and Georg Nagel “for their discoveries concerning light-gated ion channels and optogenetics.”

The Nobel Prize in Physiology or Medicine 2026 is awarded for optogenetics – a method that makes it possible to show how nerve cells shape memories, feelings and behaviours in the living brain. Peter Hegemann and Georg Nagel discovered a remarkable protein, channelrhodopsin, in a single-celled alga. Karl Deisseroth transformed the protein into a light-controlled switch for nerve cells. The laureates have laid the foundation of a new era in neuroscience.

Using optogenetics, researchers have been able to reveal neural circuits governing specific memories, feelings, and behaviours relevant for neurological and psychiatric disorders. In clinical medicine, researchers are using the method in attempts to restore sight in people with visual impairment.

Optogenetics has fundamentally altered our understanding of the brain. Every day brings new discoveries, helping to solve one of humanity’s great mysteries: how our incredible brain works.
