Nobel-winning optogenetics unlocks light-based control of brain cells

· Health · United States · Germany

The Nobel medicine prize went to US psychiatrist and neurologist Karl Deisseroth and German scientists Peter Hegemann and Georg Nagel for pioneering optogenetics, which lets scientists control neurones by stimulating them with light. The technique uses light-gated ion channels and potentially unlocks new treatments for brain disorders. France 24 explained that the method allows precise switching of specific brain cells, making it a foundational tool in neuroscience research.

Why it matters：Optogenetics has become a core research method with potential to yield treatments for psychiatric and neurological disease.

Key points

  • The trio won for controlling nerve cells using light.
  • Optogenetics uses light-gated ion channels.
  • It is now a foundational neuroscience tool.
