Karl Deisseroth wins 2026 Nobel Prize for Medicine with German colleagues
Stanford researcher Karl Deisseroth and German scientists Peter Hegemann and Georg Nagel won the 2026 Nobel Prize for Medicine on Monday for developing optogenetics tools.
Brain complexity demands precise tools
Karl Deisseroth described the human brain as a network of billions of intertwined neurons that work on a millisecond scale. He stated that neuroscientists and physicians need tools matching this complexity to treat brain disorders effectively. The researchers believe appropriate tools must be fast and capable of targeting individual cells.
Optogenetics enables cell-specific treatment
Deisseroth explained that human perception and inner states originate from cells requiring targeted intervention. His team developed methods to manipulate these specific cell types with high precision. This approach has led to experimental treatments for conditions like blindness and Alzheimer's.
