[The sex differences in the normal resting EEG of young adults (author's transl)].

In order to investigate the sex differences in the normal resting EEG, 488 healthy students (290 males and 198 females) were examined using a computer program for time domain analysis. Women show on the average more beta-waves, less alpha-waves, higher beta-amplitudes, higher average frequencies, and other signs of a higher average level of arousal. However, the total variability of all examined EEG parameters is present in both sexes. There are some hints that laterality of EEG in precentral leads could be more pronounced in males than in females.
