In seven healthy volunteers, nitrous oxide caused a dose-related impairment of memory, a reduction in tapping frequency, and an increase in inspection time. A paradoxical increase in critical flicker-fusion threshold was observed, but there was no effect on critical fusion-flicker threshold or time sense. Memory tests performed 20 minutes after withdrawal of nitrous oxide showed incomplete recovery, and subjective effects persisted for several hours.
