Visual, auditory event-related potentials, and brainstem auditory-evoked responses were recorded in as many as six young male subjects in order to study the effects of moderate cold air exposure on central nervous system functioning. Evoked potentials were recorded during repeated 50-min exposures to air of 4 and 22°C; these levels of exposure resulted in no change in rectal core temperature. Evoked potentials recorded during exposures to 4° air displayed consistently shorter latencies compared to those recorded at 22°, suggesting faster CNS processing of sensory stimuli in the cold. These results are consistent with recent investigations of cold-induced behavioral response changes which indicate that increased arousal may occur with moderate (nonhypothermic) cold exposure.
