title: Experimental data on the nature of postresuscitation alpha frequency activity.
abstract: Synchronized activity of alpha frequency recorded from a number of dog brain formations in the initial stages of postischaemic (postresuscitation) restoration was studied. Using the methods of destruction and elimination it was shown that the amygdaloid nuclei were the main source of such activity. Analysis of the general and particular coherence functions at the frequencies of alpha-like activity has shown that subcortical formations (thalamus, nucleus caudatus) become secondarily active sources of the generation of the bursts and of their generalization in the brain. Investigations and available literature lay the basis for the hypothesis that the activity observed in experiments and the activity described during postresuscitation alpha-pattern coma in humans have similar mechanisms of development and are, probably, identical.
