Relationship between Hippocampal Theta Activity and Running Speed in the Rat

Abstract

To test the hypothesis that hippocampal theta activity is related to movement, chronic EEG recording electrodes were implanted in the dorsal hippocampus and cortex of six rats. The rats were then forced to run at varying speeds on a treadmill while their brain bioelectric activity was being recorded. A close relationship appeared between amount and amplitude of hippocampal theta activity and speed of running. No such relationship was evident in cortical activity. Frequency analysis by means of a Schmitt trigger and electronic filter also demonstrated the development of 6- to 8-Hz (theta) activity in the hippocampus with running but no corresponding enhancement of 10- to 12-Hz (nontheta) activity.
