Vasopressin inhibition of cyclic AMP accumulation and effects on the learned response in inbred mouse strains

The effects of a single injection of arginine vasopressin on the cyclic AMP responses of cerebral cortex slices to noradrenaline, forskolin and 2-chloro-adenosine were tested in six inbred mouse strains. The noradrenaline response was reduced in one strain and that to 2-Cl-adenosine in 2 strains. There was a positive correlation between the differences in the cyclic AMP response to 2-Cl-adenosine between control and AVP-treated mice and the differences in latencies during the extinction period of conditioned avoidance response learning.
