The influence of ATP and AMP injected into the lateral ventricles of the brain on behavior in rats.

The influence of ATP and AMP injected into the lateral cerebral ventricle in doses of 50, 100 and 200 mug on behavior in rats was studied. ATP in the doses administered had no effect on behavior of rats. AMP in these doses enhanced motor activity of the rats. Chemical sympathectomy by intracerebral injection of 6-hydroxy-dopamine did not affect the action of either of the compounds on behavior of rats. AMP potentiated the action of intracerbrally administered noradrenaline on behavior of the animals.
