[Quantitative analysis of dendritic spines of pyramidal neurons in the layers of the sensorimotor cortex of rats exposed to the Cosmos-1667 biosputnik].
There was made a quantitative description of dendritic spine density in the layer V pyramidal neurons of sensorimotor cortex in experimental and control rats. There was found an increase the number of apical dendritic spines lying in the layers III-IV both in the flight and control experimental groups. There was also an increase in the number of oblique dendritic spines in the layers III-IV in the flight group. No changes in basal dendritic spines and apical dendritic spines were noted in the layer I-II.
