[Influence of cholinergic and adrenergic agents of the electric activity of the brain and the heart under hypoxia].
Injection of adrenergic and cholinergic agents to animals in the normal athmospheric conditions did not tigger drastic changes on the electric activity of the brain and heart. Acutehipoxia demands high adaptability from the body. In such conditions stimulation of reticular formation and hypothalamus produces different changes in the EEG and ECG activity whith injecting adrenergic and cholinergic agents. It was determined that cholinergic influence are effective in the regulation of electrical brain activity while adrenergics are more important for the realization of descending influences of the truncus cerebri vegetative centers and are less active in the modulation of the cerebral cortex activity.
