35 Day, 60 Foot Air Saturation Dive with Rats: Effects on EEG and Visually Evoked Cortical Response

Abstract

EEG and visually evoked cortical responses (VERs) were recorded from rats before, during and after a 35 day exposure to hyperbaric air at a depth of 60 feet. Recordings were obtained from chronically implanted cortical electrodes each week during the course of the dive. Although systematic changes occurred in both the EEG and VER during the experiment, similar changes occurred in a control group which remained at the surface. Thus the hyperbaric saturation exposure produced no significant changes in the EEG or VER. This result implies that long-term exposure to a depth of 60 feet does not impair the general functioning of the nervous system.
