Hypertrophic synapses as a factor of formation of persistent pathological centers in the brain in the late postresuscitation period

Clinical death was modelled on albino rats. Synapses in the molecular layer of the cerebral sensorimotor cortex were investigated 1, 2, 3, 4, 5, 6, 7, 8, and 9 months postresuscitation. The total density of synapses peaked and the number of hypertrophic and perforated contacts increased 4, 7, and 9 months after resuscitation. The role of increased number of hypertrophic and perforated contacts in the pathogenesis of postresuscitation encephalopathy is discussed.
