Bilateral septal lesions in male golden hamsters resulted in an initial postoperative response reduction on a DRL 20-sec schedule of barpressing for saccharin solution reinforcement. The animals were not water deprived. When water deprivation was instituted, the lesioned animals showed significantly higher rates of responding than the controls. Fluid consumption tests indicated that the lesion effects were not due to changes in fluid intake or saccharin preference.
