Sex differences in EEG coherence during a verbal memory task in normal adults.

摘要: Coherence analysis was applied to the EEG of 15 female and male subjects who had memorise dichotically presented lists concrete nouns. The recorded from 16 scalp electrodes placed in accordance with 10/20 system. results show significant gender-related differences total coherence reactivity due a greater increase rest task than subjects. Women differed by showing higher right hemisphere for all analysed (theta 1, theta 2, alpha 2) frequency bands. They also more extensive task-induced increases interhemispheric bands comparison single changes In women these were mainly between frontal left paired posterior other hemisphere. These findings indicate sex-related functional cortical organisation during verbal memory tasks.
