Abstract : Hippocampal bioelectrical activity and bodily movements were monitored in water-deprived naive rats who were subsequently trained to increase gross voluntary muscular activity beyond base-line levels by running back and forth in a testing cchamber 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. (Author)
