Karl Deisseroth, Peter Hegemann, and Georg Nagel have been awarded the 2026 Nobel Prize in Physiology or Medicine by the Nobel Assembly at Karolinska Institutet in Stockholm, Sweden.
They are recognized for their discovery of light-gated ion channels and the development of optogenetics, a biological technique that uses light-sensitive proteins to control specific neurons. The three laureates will share the prize money of 12 million Swedish kronor (SEK) equally.
It is to be noted that Peter Hegemann and Georg Nagel identified channelrhodopsin in green alga, while Karl Deisseroth integrated the gene into rat neurons in 2005, proving that blue light could trigger neural signals. The methodology was officially named optogenetics in 2006.
