Abstract

Medium-latency acoustic (auditory) evoked potentials (MLAEPs) were recorded in 30 men and 30 women. The MLAEPs recorded in the left and right mastoid derivations were found to be asymmetrical, the lateral differences depending on the sex: binaural stimulation and stimulation of the right ear yielded a higher total amplitude of the set of medium-latency components in the right derivation in men and in the left derivation in women. If the left ear was stimulated, there were no sex-related differences in MLAEP asymmetry. The data are discussed in terms of gender differences with respect to functional specialization of the cerebral hemispheres.
