Abstract

Hippocampal EEG, muscle tonus, and body movement were recorded during slow-wave sleep (SWS) in adult cats. A consistent correlation was seen between body movement and a change in the hippocampal EEG from large amplitude irregular activity (LIA) to theta activity. Occasionally synchronization of the hippocampal waveform also accompanied changes in muscle tonus in the absence of movement. These results are discussed in terms of recent theories of the significance of the theta rhythm and its possible implications in hippocampal function.
