[Sex differences in EEG background activity: a study with quantitative analysis in normal adults].
The present study performed quantitative EEG analysis in normal 20 males and 20 females, aged 18-26 years, in order to examine the sex differences in EEG activity at rest. The females had more absolute EEG power than the males, with significant differences observed for delta, theta and beta bands. In contrast, no significant difference was found in peak alpha frequency or relative EEG power for any frequency band. The present findings provide further evidence that females have more absolute power in resting EEG, and emphasize the importance of matching patients and control populations for sex in future investigations dealing with the relationship between resting EEG and various pathological conditions.
