Long-latency responses to bidirectional reversals in the laterality of a sound image were recorded from vertex with left and right earlobe references simultaneously. Laterality reversal stimuli with regular ISIs of 3 sec were obtained by alternating between +1 msec and -1 msec the interaural delay (ID) of dichotically presented 70 c/sec continuous click(More)
Binocular visual evoked potentials (VEP) were recorded from the left and right occipital cortices of right-handed subjects in response to six different levels of convergent disparity using the stimulus of dynamic random-dot stereogram (DRDS). The VEP obtained consisted of a negative (N1) and a positive peak (P1) within intervals of 200–400 ms and 400–600(More)
The effect of check size on pattern reversal VEPs was examined in healthy adult volunteers. The subjects were exposed to full-field binocular stimulation. Five checkerboard patterns with check sizes 13', 25', 50', 75' and 100' were used as the visual stimuli. The patterns reversed at a rate of 1 reversal/sec. Well-defined pattern reversal VEPs were obtained(More)
Binocular visually evoked potentials (VEP) were recorded from the left and right occipital cortices of right-handed subjects in response to convergent and divergent stimuli, each having six disparity levels, using dynamic random-dot stereograms (DRDS). The VEP recorded consisted of a negative peak (N300) and a positive peak (P500) within intervals of(More)
