The mean hourly spectral coherence (solid black lines) between hippocampus and cingulate cortex in the delta (A), alpha (D), and beta (G) bands; between hippocampus and insula in the delta (B), alpha (E), and beta (H) bands; and between the cingulate and insula in the delta (C), alpha (F), and delta (I) bands. The grey envelope in all cases represents the 5th and 95th percentile values produced from lagging each long recording dataseries against each other long recording dataseries by a randomly determined number of hours n, where n takes the value of 0–58.
