Cannabinoid effects on brain dopaminergic activity vary as a function of gonadal status. In this work, we examined whether these variations might be due to sex steroid-dependent differences in brain(More)
A brain constituent, the N-amide derivative of arachidonic acid, termed anandamide, has been recently proposed as a possible endogenous ligand for the cannabinoid receptor. The present study has been(More)
Alterations in the activity of striatal dopaminergic neurons have been implicated in the development of morphine tolerance-dependence in rodents. To further explore this possibility, we examined the(More)
Exposure to cannabinoids has been reported to affect several neurotransmitter systems and their related behaviors. The present study has been designed to further explore the effects of cannabinoids(More)
