Extended Data Fig. 3: The infraslow rhythm is a broadband phenomenon.
From: Sleep-dependent infraslow rhythms are evolutionarily conserved across reptiles and mammals
For each lizard species, we computed the lag (period) and the amplitude of the autocorrelation of the brain signal in the delta (1–4 Hz), theta (4–10 Hz), sigma (10–15 Hz), low-beta (15–25 Hz), high-beta (25–40 Hz) and beta (10–30 Hz) bands. We then compared the values of lag and amplitude across species using two-tailed t tests after Gaussian normalization, with a Bonferroni correction applied as a post hoc test. The number of individuals and replicates (sleep bouts) per species is indicated in Supplementary Table 1 (row ‘LFP/EEG’). The number of individuals and replicates (sleep bouts) per species is indicated in Supplementary Table 1 (row ‘LFP/EEG’). White dots indicate median value across all sleep bouts, color dots indicate all sleep bouts from all individuals and the gray vertical line indicates notch values (*P<0.05, **P<0.001, ***P<0.0001).
