    The study examined resting-state EEG spectral power in 57 healthy adults, focusing on sex hormone concentrations and their effects.

  • 2

    Sex differences in EEG spectral power were more significant than differences between menstrual cycle phases in women.

  • 3

    No significant hormone-EEG associations were found in men, while women showed focal associations of estradiol and progesterone with specific EEG bands.

  • 4

    Estradiol was linked to high gamma power, while progesterone associated with theta and high beta power in women.

  • 5

    The findings highlight the need to consider both sex and hormonal status in electrophysiological research.
