The European Brain Council warmly congratulates Karl Deisseroth, Peter Hegemann and Georg Nagel on being awarded the 2026 Nobel Prize in Physiology or Medicine for their discoveries concerning light-gated ion channels and the development of optogenetics.
Their groundbreaking work has transformed neuroscience by enabling researchers to use light to control individual nerve cells in a living brain, helping reveal how neural circuits contribute to perception, memory, emotion, and behaviour. Tools such as optogenetics have created unprecedented opportunities to explore the mechanisms of brain function and dysfunction, with long-term potential to improve our understanding of neurological and mental health conditions and to inspire new avenues for prevention, diagnosis, treatment and care.
This achievement illustrates the cumulative and collaborative nature of scientific progress. These discoveries are built on fundamental research across disciplines – from the study of light-sensitive proteins in microorganisms to carefully designed experiments in animal systems that showed how specific circuits can be investigated in the living brain. Together, they demonstrate how investment in basic research can lay the foundations for the new technologies and approaches that will ultimately improve patient care.
For the brain community, this recognition is also a powerful reminder of how far brain research has come, and of the opportunity for future groundbreaking discoveries. The brain remains one of humanity’s last great scientific frontiers: extraordinarily complex, central to who we are, how our societies work, and still only partly understood. As Europe works to strengthen its research and innovation ecosystem, sustained investment in European neuroscience must remain a priority.
The 2026 Nobel Prize is a timely celebration of the imagination, persistence, and wide-ranging research foundations required to unlock the brain’s potential. EBC applauds the laureates and the many scientific communities whose work continues to bring us closer to a future of better brain health for all.
