Visual evoked cortical potentials and related EEG activity were recorded from subjects during rapid compression and exposure to pressures of 400, 800, 1200 and 1600 fsw. In one phase, subjects made repeated excursions to 1200 fsw from a base at 800 fsw; in the second phase, the saturated base was 1200 fsw with excursions to 1600 fsw. The results included: (1) For the visual evoked potentials, sizeable and significant decreases in amplitude and increases in latency of the response with depth; (2) Changes in the visual evoked potentials which varied systematically with depth but not with related changes in compression rate or decompression. The changes were small but consistent alterations of normal responses to visual stimulation; and (3) Theta activity in discrete EEG recordings increased progressively with depth. With all subjects showed increases in theta activity the pattern of increase varied individually.
在快速压缩以及暴露于400、800、1200和1600英尺海水压力的过程中，记录了受试者的视觉诱发电位和相关脑电图活动。在一个阶段，受试者从800英尺海水的基线反复下潜至1200英尺海水；在第二阶段，饱和基线为1200英尺海水，下潜至1600英尺海水。结果包括：(1) 对于视觉诱发电位，随着深度增加，反应的幅度显著大幅降低，潜伏期增加；(2) 视觉诱发电位的变化随深度系统性变化，但不随压缩率或减压的相关变化而变化。这些变化很小，但对视觉刺激的正常反应有持续改变；(3) 离散脑电图记录中的θ活动随深度逐渐增加。所有受试者的θ活动均增加，但增加模式因人而异。
