Three researchers share 2026 Nobel medicine prize for light-based brain control
ScienceDaily reports that Karl Deisseroth, Peter Hegemann and Georg Nagel won the prize for light-based control of nerve cells.
The short version
- ScienceDaily reports that Karl Deisseroth, Peter Hegemann and Georg Nagel won the 2026 Nobel Prize in physiology or medicine.[ScienceDaily]
- The prize recognizes optogenetics, which uses light to switch nerve cells on and off, built on research into how algae sense light.[ScienceDaily]
- Optogenetics is in early-stage clinical trials for restoring vision in retinal degeneration, while studies of Parkinson's and epilepsy remain exploratory.[ScienceDaily]
Key facts
- Karl Deisseroth, Peter Hegemann and Georg Nagel were named 2026 Nobel laureates in physiology or medicine.[ScienceDaily]
- Hegemann and Nagel studied how the alga Chlamydomonas detects light using the protein channelrhodopsin.[ScienceDaily]
- Researchers introduced channelrhodopsin into nerve cells so that light could switch those cells on.[ScienceDaily]
- Optogenetics is in early-stage clinical trials for restoring vision in people with retinal degeneration.[ScienceDaily]
- Researchers are investigating optogenetics as a possible treatment for Parkinson's disease and epilepsy.[ScienceDaily]
What remains uncertain
- The article's own text names The Conversation as its source, while the reporting metadata attributes it to ScienceDaily, so the attribution is unresolved.[ScienceDaily]
- Uses of optogenetics for Parkinson's and epilepsy remain under investigation and are not established treatments.[ScienceDaily]
