Deisseroth, Hegemann and Nagel share the Medicine Nobel for light-gated ion channels — the discovery that lets scientists flip individual brain cells on and off like switches.
Optogenetics already maps Parkinson's, depression and blindness circuits. Brain-computer interfaces — the tech letting paralyzed patients move cursors — descend directly from it.
Today's curiosity Nobel is tomorrow's clinic visit. The distance from Stockholm stage to Toronto hospital is shorter than ever.
