Nobel Prize 2026 in Physiology or Medicine: Optogenetics ( by Dharmendra sir)

The 2026 Nobel Prize in Physiology or Medicine has been jointly awarded to Karl Deisseroth, Peter Hegemann, and Georg Nagel for their revolutionary discoveries concerning light-gated ion channels and the development of optogenetics! In this video, we break down how these visionary scientists bridged the gap between biophysics and neuroscience, transforming how we understand brain function and neural circuits. What we cover: • The Science of Light-Gated Ion Channels: How the discovery and characterization of channelrhodopsins in green algae paved the way for precise biological control. • What is Optogenetics? How expressing light-sensitive proteins in neurons allows researchers to activate or silence specific brain cells using flashes of light. • The Laureates: The foundational contributions of Peter Hegemann and Georg Nagel in biophysics, combined with Karl Deisseroth’s breakthrough work in engineering neural circuits. • Medical & Scientific Impact: How optogenetics continues to transform research into Parkinson’s disease, depression, addiction, epilepsy, and sensory restoration. #dharmendrasir #gyrussulcus #science #upsc #nobelprize #optogenetics #neuroscience #medicine #biophysics #sciencenews
