2026 Nobel Prize in Medicine - Optogenetics & Brain Research

The 2026 Nobel Prize in Medicine has been jointly awarded to three individuals: Karl Deisseroth (USA), Peter Hegemann (Germany), and Georg Nagel (Germany).

This award has been given for the research on 'Optogenetics', which precisely controls nerve cells (neurons) in the brain using light.

🎯 TNPSC Exam Key Notes:

• 2026 Nobel Prize in Medicine recipients: Karl Deisseroth (USA), Peter Hegemann (Germany), Georg Nagel (Germany).
• This prize has been awarded for discovering the 'Optogenetics' method, which controls nerve cells using light.
• This technology helps in developing new treatment methods for neurological disorders such as Parkinson's, Alzheimer's, and depression.
• The human brain contains approximately 86 to 100 billion neurons; these transmit information via synapses (Synapse).
• The Nobel Prize is awarded annually on Alfred Nobel's memorial day, December 10, in Sweden (the Peace Prize is awarded in Norway).

📌 KEY FOR TNPSC:

• Optogenetics has revolutionized neuroscience research by combining genetics (Genetics) and optics (Optics).
• Indian/Indian-origin medical scientist who received the Nobel Prize: Har Gobind Khorana (1968 - genetic code research).
