Women vs men differences in measured and parametrized mean NREM sleep EEG spectral power at electrode location C4. The natural logarithm of pectral power was averaged in women and men (continuous lines), as where individual fits (dotted lines) acoording to our current method (see details in section “Methods”). Note the overall amplitude differences (women > men), as well as the higher spectral peak frequencies (fmaxPeak) in women and the lack of differences in spectral peak amplitudes (PPeak(fmaxPeak)). IQR interquartile range.
