Abstract
The effects of apomorphine upon stereotype and bromocriptine upon wheel running and intracranial reward were examined across the estrous cycle of female rats. Apomorphine elicited stereotypy in a dose-related fashion, but stereotypy was not reliably or systematically altered by estrous conditions. On the other hand, wheel running was augmented by bromocriptine in an estrous-specific fashion. Self-stimulation was increased by bromocriptine but this was not related to estrous cyclicity. These findings provide evidence for possible behavioral and motivational specificity of dopamine (DA) receptor-related estrous changes.
