"both ripple and epsilon waves have low coherence (<0.2) between CA3 and CA1, indicating that timing of events are established largely independently in the two regions."

Theta (4-12 Hz) coherence between CA1 and mPFC: .32 +/- 0.03

Theta (4-12 Hz) coherence between CA1 and mPFC is ~0.20 to ~0.30 depending on the part of the task.
