title: Photic responses in hyperkinesis of childhood.
abstract: Intravenous injections of drugs that stimulate the central nervous system decreased photic driving responses and photoinyoclonic responses in hyperkinetic children. Neither injections of saline in these children nor injections of stimulant drugs in normal subjects produced such diminution. The neurophysiological implications are discussed.
