Briefings

The 2026 Nobel Prize in Physiology or Medicine was awarded to Karl Deisseroth, Peter Hegemann, and Georg Nagel for their pioneering work in optogenetics, a technique that enables precise control of neurons using light. This breakthrough revolutionized neuroscience by allowing researchers to activate or inhibit specific neural circuits with high temporal and spatial accuracy, fundamentally changing how scientists study brain function and behavior. The study was published in Nature on October 5, 2026, and the team's work has since been widely cited in major scientific journals, establishing optogenetics as a cornerstone method in modern neuroscience research.
