Briefings

US psychiatrist Karl Deisseroth and German colleagues Peter Hegemann and Georg Nagel received the Nobel Prize for their pioneering work in optogenetics, which allows scientists to control neural activity with light. This breakthrough enabled researchers to observe and manipulate specific brain cells in living animals, fundamentally advancing the understanding of how the brain processes information. The study involved injecting light-sensitive proteins into the brains of mice to trigger precise electrical signals, providing a new tool for investigating neurological disorders and cognitive functions.

Key points

• Karl Deisseroth, Peter Hegemann, and Georg Nagel were awarded the Nobel Prize for their development of optogenetics, a technique that uses light to control neural activity in living animals.
• The research involved injecting light-sensitive proteins into the brains of mice to trigger precise electrical signals, allowing scientists to observe and manipulate specific brain cells in real-time.

Context and limitations

The evidence provided is limited to the announcement of the Nobel Prize and does not include details on the specific experimental methods, the number of animals used, or the long-term outcomes of the studies.
