Visual Evoked Responses and EEGS for Divers Breathing Hyperbaric Air: An Assessment of Individual Differences

Abstract

In order to assess individual differences in susceptibility to nitrogen narcosis, a group of 16 men made repeated air dives to approximately 200 ft in a pressure chamber. The visual evoked response of the men at depth revealed several decrements: in the response to a slow rate of stimulation, there was a highly significant reduction in a component around 160 msec; in the response to a rapid rate of stimulation, marked losses in amplitude and increases in variability were found. The latter changes were related to diving experience while the former were not. No significant changes were found in alpha or theta activity in the EEG.
