The effect of physiological arousal on interhemispheric transmission time (IHTT) was investigated. Since physiological arousal produces changes in neurotransmitter activity, these changes could result in a decrease in IHTT. IHTT was measured with a simple reaction time (SRT) experiment using an IBM PC model 80 computer and customized software. Physiological arousal was produced in 24 subjects through the presentation of a loud (90dB) white noise. Twelve were not submitted to the noise. The results were inconclusive due to inaccurate measurements of IHTT. A possible reason for these results could be the location of the stimulus. The light flash presented to subjects to stimulate a response may have been situated too close to the centre of the subject's field of vision rather than in the left or right visual fields.
