Fig. 4

a Example PSD of LFPs recorded from a single animal in the VP during the three HMM-derived states. b Scatter plots showing the spectral power at gamma frequencies (40–60 Hz) during DMN-related behavioural activity vs exploratory behaviours in the four brain areas. Axes are the same as in (d). Symbol colours denote different animal subjects, see the legend. c Average magnitude of the difference in gamma power between DMN and exploration behaviours in the four brain areas. Error bars depict SEM. d, e same as (b, c) but for the high-gamma band (60–150 Hz). f Average directional interaction strength (Granger causality) calculated for the gamma band (40–60 Hz) between VP, AC, MD, V1 during DMN-related states. Line thickness proportional to the magnitude of the Granger Causality. g Directional interactions among DMN-related sites (VP, AC, MD) during DMN-related states for gamma, left, and high-gamma band, right (lines represent P < 0.01). h Scatter plots comparing overall Granger causality values within VP, AC and MD between DMN and exploratory behavioural states. Error bars depict SEM.
