Nonstationary uncoupled 45 Hz oscillations. In (A–D), we show the average comodulogram for 50 realizations of a signal containing an uncoupled oscillation of center frequency 45 Hz with bandwidth 45 Hz, obtained with: (A) BPAC1; (B) BPAC2; (C) DFPAC; and (D) IMPAC. In (E–H), we show histograms of the phase and amplitude frequency bins at which the maximum PAC is observed, for all bandwidths, and the methods in the same order.
