Norepinephrine-sensitive adenylate cyclases in rat brain: relation to behavior and tyrosine hydroxylase

Responses of norepiniephrine sensitive adeniosinie 3',5'-monophosphate (cyclic AMP)-generating systems in combined midbrain-striatal slices of four rat strains correlate positively with spontaneous behavioral activity and negatively with levels of midbrain and striatal tyrosine hydroxylase. Responses of cerebral cortical norepinephrine-sensitive cyclic AMP systems correlate negatively with spontaneous behavioral activity antd positively with midbrain and striatal tyrosine hydroxylase. Such correlations were not found with responses of the cyclic AMP- generatinlg systems to isoproterenol, adenosine. veratridine or of an adenosne and norepinephrine combination.
