English #neurologist whose studies of #epilepsy, #speech defects, and nervous-system disorders arising from #injury to the #brain and #spinalcord remain among the most useful and highly documented in the field.
He was one of the first to state that abnormal #mental states may result from structural brain damage.
Jackson's epilepsy studies initiated the development of modern methods of clinical localization of brain lesions and the investigation of localized brain functions.
His definition (1873) of epilepsy as "a sudden, excessive, and rapid discharge" of brain cells has been confirmed by #electroencephalography, a method of recording electric currents generated in the brain.
