Informativeness of cerebral cortical interneuronal synapses in rats after asphyxia


The intensity of specific interneuronal exchange depends on the number and size of the active zones of synaptic contact (AZC) which, according to Bogolepov [i], determine the informativeness of the synapse. It has been shown that AZC of different types of synapses differ in their functional role in the mechanism of trans-synaptic transmission [4, 5]. This difference is based on the unequal degree of maturity of the system of subsynaptic units (SSU), formed by paramembranous microfilaments of the cytoskeleton of the synapses. Many investigations have been devoted~to the analysis of changes in synapses in the developing and mature brain under normal and pathological conditions, including in the postresusciration period [1-3, 6, 7]. However, there has been no research aimed at explaining the principles governing the change in informativeness of interneuronal synapses and the synaptic pool in the brain, taking account of synapses differing in their functional maturity, in the course of the recovery period after a terminal state.
