later 1st Baron Adrian of Cambridge
born Nov. 30, 1889, London, Eng.
died Aug. 4, 1977, London
British electrophysiologist.
He amplified electrical potential variations in nerve impulses from sense organs to record ever smaller changes, eventually recording impulses from single sensory endings and motor nerve fibres. His work clarified the physical basis of sensation and the mechanism of muscular control. Adrian's later studies of brain electrical activity included investigations into epilepsy and the location of cerebral lesions. He shared a 1932 Nobel Prize with Charles Sherrington .
