Participation of thalamic nuclei in the elaboration of conditioned avoidance reflexes of rats. VII. Lesions of the nucleus lateralis posterior.
Bilateral lesions of the nucleus laterials posterior thalami (LP) scarcely changed preoperatively learnt conditioned avoidance responses (CAR) in a runway and the Y-maze. Postoperative elaboration of CAR showed some difficulties in the runway which were increased during alternation training in the Y-maze. All rats with LP lesions had severe disturbances of spatial orientation in new situations, which could be overcome by training.
