Abstract
The multichannel autoregressive model and the periodogram approach are used to determine coherence and phase measures between the electrical activity in two distinct brain structures of the rat namely, the subfields CA1 and dentate gyrus in the hippocampal formation, during the vigilance states of quiet waking (QW), slow-wave sleep (SWS), and rapid-eye-movement (REM) sleep. Using both periodogram and multichannel autoregressive modeling techniques, high coherence and consistent phase differences were found to exist within the theta range of frequencies (4-11 Hz) only during REM sleep
