Abstract
Eleven gerbils (Meriones) were tested for self-stimulation in posterior hypothalamic loci while hippocampal activity was monitored. Rewarding brain stimulation produced synchronization (theta) or regularization of hippocampal activity; no rebound of hippocampal desynchronization was observed immediately following termination of stimulation. Several seconds following termination of stimulation, however, "footstomping" behavior was observed. This activity was seen following, never during, rewarding brain stimulation. Hippocampal activity was most often desynchronized during this species-typical behavior pattern. Synchronization-desynchronization shifts in hippocampus previously thought to reflect reward-aversion were interpreted to reflect the participation of two mechanisms subserving, respectively, stimulus-related and motor-organizational processes.
