Fig. 2 — Spectral densities in anesthesia, NREM, and wake. (a) The average ( $n = 5$ ) GCaMP6 (solid lines) and ${HbO}_{2}$ (translucent lines) power for each brain state plotted with the delta band (0.7–3.0 Hz) highlighted. (b) Log10 average ( $n = 5$ ) GCaMP6 delta (0.7–3.0 Hz) power topographs for each brain state. (c) Average ( $n = 5$ ) GCaMP6 delta lag topographies for each brain state.
