[Changes in the parameter of asymmetry of EEG wave fronts in patients with cerebral circulatory disorders treated with instenon].

The distribution of the parameter of asymmetry of the wave fronts in EEG on the convexital surface of the cortex during instenon administration is significantly changed in time and becomes normal after 3 hours of observation. This may point to an improvement of the functional state of the brain under the influence of the drug. The most distinct positive dynamics in such conditions were marked in patients with general brain symptoms and transient disorders in the vertebro-basillar system. A transition of desynchronized EEG to hypersynchronized with a subsequent normalization of the structure is apparently conditioned by the central influence of the preparation on the synchronizing areas of the brain reticular formation.
