Hypoxia is a common candidate for the retrograde amnesic action of ECS, chemoconvulsants, anaesthetics and cerebral trauma. Gherkin (6.10) investigated the effects of exposure to an atmosphere of low oxygen immediately following a one-trial learning task in which ECS and halothane have been shown to produce retrograde amnesia. Memory retention was not impaired by hypoxia and hyperoxia had no significant effect on retention either.
