The award to the three researchers was reported by both ANSA and France 24, which agree on the joint recognition of Karl Deisseroth, Peter Hegemann and Georg Nagel.
According to ANSA, the prize recognizes work that laid the foundations of optogenetics.
The information provided therefore links the Nobel Prize to research on optogenetics, identified by ANSA as the field to which the three scientists made a foundational contribution.
The announcement of the award was published on October 5, 2026, according to the information reported by the two sources.
The prize thus brings together, in the same award, the names of Deisseroth, Hegemann and Nagel and the reference to the foundations of optogenetics indicated by ANSA.
The available information does not specify where the prize was awarded or provide a more detailed institutional designation beyond the Nobel Prize in Medicine.
