Power spectral shifts in hippocampal EEG associated with conditioned locomotion in the rat

Abstract

Hippocampal bioelectrical activity and bodily movements were monitored in water-deprived naive male rats who were subsequently trained to increase gross voluntary muscular activity beyond base-line levels by running back and forth in testing chamber for water reward. This procedure led to a marked increase in theta wave activity in the hippocampus. Extinction of the behavioral response was paralleled by a decline toward base-line levels of movement and theta wave activity. Reconditioning of hyperactivity led to a concomitant increase in theta activity as recorded from the hippocampus.
