Three researchers — Karl Deisseroth, Peter Hegemann and Georg Nagel — have been awarded the 2026 Nobel Prize in Physiology or Medicine for “discoveries concerning light-gated ion channels and optogenetics,” the award-giving body announced on Monday.
Chosen by the Nobel Assembly at Sweden’s Karolinska Institute medical university, American scientist Karl Deisseroth, 54, alongside German researchers Peter Hegemann, 71, and Georg Nagel, 73, will share the 12 million Swedish crowns ($1.2 million) prize sum.
Optogenetics “makes it possible to switch on, or off, the activity of individual nerve cells in a living brain,” the prize-givers stated, noting: “This method is now being used in laboratories around the world to reveal the brain’s mysteries.”
The announcement for physiology or medicine traditionally marks the beginning of the annual Nobel awards, with physics, chemistry, literature, peace and economics set to follow over coming days.
Established under the will of Swedish inventor and industrialist Alfred Nobel, the five original prizes have been presented since 1901, with only limited interruptions, chiefly during World War One and World War Two.

The medicine prize has honoured some of the most influential scientific discoveries of the past century, including Alexander Fleming’s work on penicillin, recognised in 1945, and Karl Landsteiner, who won in 1930 for his discovery of human blood groups.
Last year, American scientists Mary Brunkow and Fred Ramsdell and Japan’s Shimon Sakaguchi won the prize for work shedding light on how the immune system spares healthy cells, creating openings for possible new treatments of diseases such as cancer.
Nobel laureates are chosen by expert committees appointed by the prize-awarding institutions. The awards are presented in Stockholm, with the exception of the Peace Prize, which is handed out in Oslo, a tradition often linked to the union that bound Sweden and Norway during Nobel’s lifetime.
More than 125 years after Nobel signed his will, the prizes retain many of their longstanding traditions.
The celebrations culminate on December 10, the anniversary of Nobel’s death, when laureates receive their awards in ceremonies attended by Sweden’s and Norway’s royal families and are feted at gala banquets held in their honour.
