Sex differences in intracranial EEG relative band power

Ascertain whether sex influences relative band power measured from intracranial EEG recordings and, if so, characterize any frequency-band-specific sex effects.

Background

In this cohort, sex explained a negligible portion of variance in relative band power, whereas age showed band-specific relationships. However, prior MEG and scalp EEG studies have reported sex differences, particularly in absolute power rather than relative power.

Given modality and feature differences between studies and the null findings here for relative power in intracranial EEG, it remains unresolved whether sex differences exist for this specific measure.

References

In summary, the age trajectories we have found are generally in line with previous literature in similar areas, but a conclusion on the presence of sex differences remains unclear.
