Karl Deisseroth, Peter Hegemann and Georg Nagel have been awarded the 2026
#NobelPrize in Physiology or Medicine for discoveries leading to optogenetics, which makes it possible to switch on, or off, the activity of individual nerve cells in a living brain.
This method is now being used in laboratories around the world to reveal the brain’s mysteries.
