Roger Sperry
The split-brain experiments that everything about hemispheres ultimately rests on are his.
Sperry's work with patients whose hemispheres had been surgically separated established that the two halves process information differently and can operate with startling independence once the connection between them is cut. He shared the 1981 Nobel Prize in Physiology or Medicine for it.
The findings are solid and they are narrow. They describe what happens in an unusual surgical situation, and they say something real about specialisation. They do not support sorting ordinary people into left-brained and right-brained types, a conclusion Sperry himself did not draw and which later imaging work has failed to find.
