[The involvement of intracellular regulatory systems in the mechanisms of the recovery of the neuronal activity of the cerebral cortex in anoxia].

Abstract

Changes in the membrane-bound calcium (Ca(b)), polyphosphoinositides (PPI) and cAMP, as well as unit spike activity of the cat brain cortex were studied during 30 min of recovery after 5-min anoxia. The cats with poor recovery revealed low Ca(b) and PPI but high level of the cAMP content. The group of cats with more successful restitution after anoxia revealed a sharp increase in the Ca(b) and PPI and not in the cAMP.
