Cum a devenit lumina o telecomandă pentru creier și a câștigat un Premiu Nobel

A blind patient partially regained vision through optogenetics, a technique that uses light to control cells. The 2026 Nobel Prize in Medicine was awarded to Karl Deisseroth, Peter Hegemann, and Georg Nagel for their work on light-controlled ion channels. Optogenetics allows researchers to manipulate specific cells in a living brain, enhancing the understanding of neural circuits and behavior. The method originated from studies on the algae Chlamydomonas, leading to the discovery of light-sensitive proteins called channelrhodopsins. This technique is now being applied in clinical trials for retinal diseases, showing promise in restoring vision.
