Karl Deisseroth, Peter Hegemann and Georg Nagel have been awarded the 2026 Nobel Prize in Physiology or Medicine, according to Legit.ng. The report says the Nobel Assembly recognised discoveries involving light-gated ion channels and optogenetics.
The technique gives researchers a way to use light to control selected nerve cells, helping them investigate how neural circuits relate to memory, emotions and behaviour. The award recognises a research breakthrough, rather than announcing a new treatment available to patients. This brief reports the prize announcement and its scientific context as described in the linked coverage; it does not offer medical advice or make claims about an individual’s care.
