[Role of certain brain structures in the generation and spread of alpha-like activity in dogs peculiar to the early stages of the postresuscitation period].

The role played by the amygdaloid nucleus, caudate nucleus, thalamus and brain cortex in propagation throughout the brain of generalized limbic alpha-like activity recorded on the EEG in the early postresuscitation period was studied in experiments on dogs resuscitated after a 13-15-minute circulatory arrest. Destruction or pharmacological inhibition of both amygdaloid nuclei resulted in disappearance of alpha-like activity from all the test structures. Coherent analysis showed that the caudate nucleus and thalamus, in particular, take an active part in propagation of alpha-like waves of biopotentials from the amygdaloid nucleus to other brain structures.
