Abstract
Intracerebroventricular (ICV) bombesin increases grooming and decreases food intake in rats. We examined tolerance to these effects by administering a daily injection of either saline or 25 ng bombesin to rats for 8 days via lateral ventricular cannulas. Food intake and grooming were monitored. After 8 days bombesin no longer increased grooming or decreased food intake in bombesin-treated rats, but did increase grooming and decrease food intake in saline-treated rats. This development of behavioral tolerance conflicts with previous reports using larger doses and demonstrates that repeated small doses of ICV bombesin produce different effects from larger doses.
