Three scientists, Karl Deisseroth, Peter Hegemann, and Georg Nagel, were awarded the 2026 Nobel Prize in Physiology or Medicine for their groundbreaking work on light-gated ion channels and optogenetics, announced the Nobel Assembly on Monday in Stockholm. Optogenetics enables the manipulation of individual nerve cells in a live brain, uncovering the brain’s inner workings in labs worldwide.
The laureates, Deisseroth from the United States, Hegemann, and Nagel from Germany, expressed their delight in sharing the prestigious award, emphasizing their camaraderie and mutual respect. The Nobel Prize carries a monetary award of 12 million Swedish crowns, to be divided among the three scientists, who are affiliated with esteemed institutions such as Stanford University and Humboldt University.
According to Nobel committee member Anna Wedell, optogenetics heralds a new era in neuroscience, offering insights into how the brain processes information and the interactions among different neurons. The technology has shown promise in clinical trials by restoring vision in individuals with retinitis pigmentosa and holds potential for enhancing cochlear implants for precise stimulation of the auditory nerve.
The journey to this scientific breakthrough began in the early 1990s when Hegemann and Nagel identified channelrhodopsin-2, an ion channel activated by light. Deisseroth later demonstrated the application of this discovery in nerve cells, coining the term “optogenetics.”
The Nobel Prize awards for physics, chemistry, literature, and peace will follow in the coming days, with the economics prize announcement scheduled for October 12. The prestigious accolades were established by Alfred Nobel, a polymath known for his invention of dynamite and his dedication to benefiting humanity. Nobel’s legacy lives on through the annual award ceremony on December 10, commemorating his legacy and contributions to innovation and peace.
