[Effect of cyclic 3',5'-adenosine monophosphate on central neurons].
In experiments on unanesthetized non-immobilized rabbits, unit responses in the cortex and thalamus to the cyclic 3',5'-adenosine monophosphate (cAMPh) were studied by means of microionophoresis. It was shown that cAMPh changes the pattern of background unit activity, increasing or decreasing the discharge frequency. cAMPh changes unit responses both to acetylcholine and noradrenaline. These data permit, to assume that cAMPh participates both in adrenergic and in acetylocholinergic mechanisms of excitation processing in brain neurones.
