Three Navy divers were exposed to a normoxic breathing mixture at 7.0 ATA for seven consecutive days. Visual evoked responses (VER's), electroencephalograms (EEG's) and simple reaction time (RT) were measured. Previously reported amplitude decreases in a VER to a flash rate of 1 Hz (VER 1) and to a flash rate of 16 Hz (VER 16) were again found during this dive. The variability of the VER 16 and the latency of the VER 1 also increased during the saturation period. In the EEG analysis, changes in the amplitude of both alpha and theta were found, as were decreases in alpha frequency. The RT task showed a marked elevation of response time at the beginning of the dive period which gradually returned to predive levels. Latency of the VER 160-180 ms component was highly correlated with the changes in RT. The results are discussed in terms of information processing and cerebral dysfunction.
三名海军潜水员连续七天在7.0ATA的常压呼吸混合气环境中暴露。测量了视觉诱发电位（VER）、脑电图（EEG）和简单反应时间（RT）。在此次潜水过程中，再次发现先前报道的VER对1Hz闪光频率（VER 1）和16Hz闪光频率（VER 16）的幅度下降。在饱和期，VER 16的变异性和VER 1的潜伏期也增加。在脑电图分析中，发现α波和θ波的幅度都有变化，α波频率也降低。RT任务显示在潜水期开始时反应时间显著延长，随后逐渐恢复到潜水前水平。VER 160 - 180ms成分的潜伏期与RT的变化高度相关。从信息处理和脑功能障碍方面对结果进行了讨论。
