[Structural changes in dendritic spines of the pyramidal neurons of layer III of the rat sensory-motor cortex during remote postischemic period].
The combination of Golgi method with the lipid phosphorilate mark Dil (1,1'-dioctadecyl-3,3,3 cents, 3 cents-tetramethyl-indocarbocyanine perchlorate) and confocal laser scanning microscope for demonstration of the structure of dendritic tree and dendritic spines enables exact determination of spatial organization of small dendrites and their spines at significant distances in norm and especially in postischemic period. The regularities of dendritic spine reorganization in layer III pyramidal neurons of the cerebral sensory-motor cortex during 9 months after short-term (10 min) total brain ischemia were established.
