Abstract

Using confocal microscopy, the qualitative and quantitative characteristics of the human brain cortex neurons in normal state and after clinical death (reperfusion) was studied. Actual data obtained on autopsy material (n=7) using histological, immunohistochemical (MAP-2, GAP-43, R38) and morphometric research methods. It is established that axons, dendrites and synapses possess had a high degree of tolerance to ischemia and reperfusion, as well as the ability to restore neuronal relations. After reperfusion in the surviving neurons of the human cortex revealed a high content of the marker of dendrites (MAP-2), axons (GAP-43), synaptic vesicles (p38). On the background of the intact cytoskeleton of dendrites, terminals, axons with high potential plasticity existed untapped reserve of synaptic vesicles with the neurotransmitter. This evidence of structural and functional conservation of all components of the communicate system a significant part of the human cortex neurons after reperfusion.
