[Effect of beta-adrenergic blockaders on the bioelectrical activity of the mesenchephalic reticular formation].

The authors examined the beta-adrenergic structures in the mesencephalic formation (MSF) in view of establishing their role on the activity of MSF in view of establishing the in rols on the activity of MSF itself and the relationship of the same formation with the cerebral cortex and the lymbic system. It was established that beta-adrenergic blockers after their local application in MSF could inhibit its function. The data from the effect on the induced bioelectrical activity indicated also diminution in the functional activity of MSF. The authors found that the inhibiting influences of beta-blockers were abolished by their antagonist isoprenalite. An inference is made that there are beta-adrenergic structures, which act excitatory.
