Abstract
Semistarved rats develop high running wheel activity. This running activity induces increased norepinephrine, dopamine, and serotonin turnover in the hypothalamus. Corticosterone in plasma becomes increased while luteinizing hormone and testosterone are suppressed. In female rats cyclic gonadal function is suppressed. Running activity in the semistarved rats can be suppressed specifically by serotonin 1-c-agonists and by alpha 2-adrenoceptor agonists. This animal model is helpful in the understanding of the combined effects of starvation and hyperactivity, which are observed in many patients with anorexia nervosa. The observation of the serotonergic system might help to develop a pharmacological treatment of hyperactivity in anorectic patients.
