Fig 7. The 1/frequency distribution of amplitude modulation of MEG signal intensity. A, Full-field power spectrum of unfiltered MEG signal intensity in 1 subject, resting state. Note that most of the power comprises 
activity. B, The power spectrum for amplitude modulation of activity from data in Fig 6B. A 1/frequency curve shows excellent fit to the data. C, Amplitude modulation of 
activity. Full-field power spectrum with inset showing zoomed-in region of the curve up through 0.5 Hz. Data show averages from normalized power spectra from 6 subjects. D–F, As per Fig 7C for , β, and 
activity, also averaged from 6 subjects.
