Dissociation of the effects of bilateral lesions of the dorsal hippocampus and parietal cortex on path integration in the rat.

摘要: Rodents are able to rely on self-motion (idiothetic) cues and navigate toward a reference place by path integration. The authors tested the effects of dorsal hippocampal parietal lesions in homing task dissociate respective roles hippocampus cortex Hippocampal rats exhibited strong deficit learning basic task. Parietal displayed performance impairment as function complexity their outward paths when food was placed at varying locations. These results suggest that plays specific role integration processing idiothetic information, whereas is involved calibration space used system.
