Abstract
The effects of intracerebroventricular administration of synthetic ovine corticotropin-releasing factor (CRF 1-41) have been investigated on the retention of passive avoidance behaviour, and on the dopamine, norepinephrine and serotonin contents of the hypothalamus, mesencephalon, amygdala, septum and striatum, as well as on the plasma corticosterone levels of hypophysectomized and sham-operated rats. Treatment with CRF 1-41 20 min before the first retention test, 24 hours after the learning trial, significantly facilitated the passive avoidance behaviour of hypophysectomized animals in a dose-dependent manner. No effect was found in sham-operated rats. No significant effects of a wide dose range of intracerebroventricularly injected CRF on the monoamine contents of limbic brain structures were detected. However, the same doses of CRF 1-41 increased the plasma corticosterone level in sham-operated rats. The data suggest that the release of CRF from neurons in the limbic system does not alter the monoamine contents in this system, although this peptide facilitates the retention of the passive avoidance behaviour of hypophysectomized rats.
