Spatio-temporal cortical activity Events and Motifs. (a) Example Waking Event, comprising a sequence of HG peaks occurring within 2s. A.U.: arbitrary units. (b) Example spatio-temporal Motif of HG peaks. Events were spatially- and temporally-clustered to obtain 60–250 representative Motifs for each subject, each with >20 Events (see “Motif selection and matching index analysis” in Methods and Fig. S1). Motifs with the most representative temporal order were matched against Events found in NREM (Fig. 3a). (c) Example NREM Event whose HG peaks come from channels involved in the Motif to the left and are in the same temporal order as the same channels’ HG peaks in the Motif.
