Summary
A norepinephrine-sensitive cyclic AMP generating system is present in slices of rat limbic forebrain. The system has properties of a noradrenergic receptor and seems to be involved in the action of psychotropic drugs. It is hypothesized that desensitization of the system is the basis of action of psychic antidepressants.
