Extended Data Fig. 7: Infraslow rhythms are specific to sleep.
From: Sleep-dependent infraslow rhythms are evolutionarily conserved across reptiles and mammals
a, Same as Fig. 3b,c for a wake recording in the bearded dragon. Top, LFP power in the beta band in the DVR before (black) and after (red) detrending, and the autocorrelation maps computed over a 2-min sliding window. First positive (red) and negative (gray) peaks are displayed. Right, mean auto-correlogram. Middle, same as top, for the mean cerebral blood volume of the whole brain. The absence of strong positive peaks in both auto-correlograms reveals the absence of infraslow rhythm in wake. Bottom, cross-correlogram between LFP and CBV data with the mean cross-correlation function on the right. The low cross-correlation values reveal a low coupling during wake. b, Same as Fig. 3e,f for a wake recording in the mouse. Top, LFP power in the beta band (10–30 Hz) in the DVR before (black) and after (red) detrending, and the autocorrelation maps computed over a 5 min sliding window. First positive (red) and negative (gray) peaks are displayed. Right, mean auto-correlogram. Middle, same as top, for the mean cerebral blood volume of the whole brain. The absence of strong positive peaks in both autocorrelograms reveals the absence of infraslow rhythms in wake. Bottom, cross-correlogram between LFP and CBV data with the mean cross-correlation function on the right. The low cross-correlation values reveal a low coupling during wake, with a reinstatement of high values during NREM sleep.
