The Visual Evoked Cortical Response as a Measure of Stress in Naval Environments: Methodology and Analysis. (1) Slow Flash Rates

The Visual Evoked Response as a Measure of Nitrogen Narcosis in Navy Divers

“…It is interesting to note, however, that this time period has been implicated in the response to patterned stimuli. 7 -…”

“…It seems safe to assume that real differences in waveform do occur at depth, but the degree of the effect and its reliability need to be quantified. In order to do this, a technique of measuring the amplitude and latency of various components of the VER, worked out in a previous experiment, 7 has been employed. The first step in the analysis is to determine the major components for each subject by comparing the 10 surface control records.…”

Measures of Evoked Responses and EEGs during Shallow Saturation Diving

“…Previous research has shown the two flash rates yields a sensitive measure of physiological stress, since they yield different evoked responses which probably have somewhat different origins. 14 * 15 The intensity setting of the Grass photo stimulator was 4. This setting yielded a luminance of about 80 foot-Lamberts for the bright stripes.…”
