Corticotropin-releasing factor (CRF) administered intracerebroventricularly (ICV) to rats and mice has been shown to elicit a variety of behaviors resembling those that occur in stress. In a novel multicompartment chamber, ICV CRF altered the behaviors in a manner closely resembling that observed following a period of restraint. In particular, 75 ng CRF ICV or 30-40 min restraint markedly reduced the time mice spent in contact with novel stimuli. ICV injections of a peptide antagonist of CRF, alpha-helical CRF9-41 (ahCRF), reversed the effects of restraint on this measure. This effect of ahCRF was dose dependent, with a minimal effective dose of 10 micrograms. Other behavioral measures appeared normal, and ahCRF did not significantly alter the stimulus-contact time in unrestrained mice. These results provide strong evidence to support the hypothesis that endogenous CRF may be a factor affecting stress-induced changes in exploratory behavior in mice.
