The Nobel Prize in Medicine was awarded to three researchers in the field of optogenetics

The Nobel Prize in Medicine was awarded to the American Karl Deisseroth and the Germans Peter Hegemann and Georg Nagel in recognition of their research in the field of optogenetics, according to what the Nobel Committee announced in Stockholm on Monday (October 5, 2026) on the first day of the season of these prestigious awards for the year 2026.

The committee indicated that it granted the award to the three researchers “in recognition of their discoveries related to ion channels activated by light and optogenetics.”

This field helps researchers understand how specific cell types contribute to behaviors such as learning, fear, addiction, and movement, and may one day lead to treatments for neurological and sensory disorders, such as Parkinson's disease and epilepsy.

“Using optogenetics technology, researchers were able to uncover the neural circuits that control specific memories, feelings, and behaviors associated with neuropsychiatric disorders,” the Nobel Committee said.

In clinical medicine, researchers use this method in attempts to restore sight in people with low vision.

The committee added, "Optogenetics has radically changed our understanding of the brain. Every day brings new discoveries that help solve one of humanity's greatest mysteries: how our amazing brain works."

The Nobel Prize in Medicine was awarded last year to Mary Bronko and Fred Ramsdell from the United States and Shimon Sakaguchi from Japan, in recognition of their research on how the body controls the immune system.

The winners of this year's award, which includes a certificate, a gold medal, and a check worth $1.2 million, will receive their awards from King Carl
