Figure 5.
Changes in hippocampal network coordination during phasic REM versus tonic REM and active waking. A–F, Changes in theta and gamma synchrony (left and right panels of each subplot, respectively) between phasic and tonic REM sleep (A–C) (phasic − tonic) and between phasic REM and active waking (D–F) (phasic − waking). A, B, D, E, Group statistics show changes in CSD power (A, D) (decibels; ±SEM; Bonferroni-corrected t tests) and coherence (B, E) (dot color, mean within-site change; dot size, significance of Bonferroni-corrected t tests; *p < 0.01). C, F, Examples from one recording session showing anatomical maps of coherence changes with respect to a single reference site (white pixel) illustrating the highlighted group of layer pairs (dotted outline) in B and E. Abbreviations are as defined in the legend to Figure 2.
