Abstract:
The effects of chronic lithium treatment on adenylate cyclase activity in intact rat brain were examined using in vivo microdialysis. Basal extracellular cyclic adenosine monophosphate (AMP) increased in a dose-dependent manner after norepinephrine was added to the perfusate. Chronic lithium treatment increased basal brain extracellular fluid cyclic AMP levels, while decreasing the magnitude of the cyclic AMP response to stimulation with 100 microM norepinephrine.
