Three scientists received the 2026 Nobel Medicine Prize for work on light‑gated ion channels.
Their discovery created the field of optogenetics, enabling precise control of nerve cells with light.
The method is applied globally in research to explore brain mechanisms and potential therapies.
Optogenetics allows researchers to switch individual nerve cells on or off with light, providing a powerful tool to study brain function.
The technique is now being used in laboratories worldwide to uncover how the brain works and could lead to new medical treatments.
