The 2026 Nobel Prize in physiology or medicine has been awarded to three scientists – Karl Deisseroth, Peter Hegemann and Georg Nagel – for their work developing a technique to decode the inner workings of the brain.

The German duo of Hegemann and Nagel discovered a protein, known as channelrhodopsin, before American scientist Deisseroth “transformed the protein into a light-controlled switch for nerve cells,” the Nobel Committee said in a statement. That work has “laid the foundation for a new era in neuroscience,” the committee added.
By using this method, known as optogenetics, researchers can illuminate neural circuits which govern “specific memories, feelings, and behaviors relevant for neurological and psychiatric disorders.”

David Pendlebury, head of research analysis at Clarivate’s Institute for Scientific Information, said the award highlighted the “profound impact of a field that has fundamentally changed how scientists understand the brain and nervous system.”
“The Nobel Committee’s recognition underscores the extraordinary influence of this work, which has transformed neuroscience by enabling researchers to use light to precisely control and study neural activity,” Pendlebury said.
