[The dendritic plasticity of the pyramidal neurons in layer V of the rat sensorimotor cortex in the postischemic period].

Dendrites plasticity of pyramidal neurons in layer V of rat sensomotor cortex was analyzed during postischemic period. Oblique dendrites and their spines of pyramidal neurons were more reactive for ischemia after 1 day aa manifested by decrease in their length, branching, the volume of dendritic territory and number of dendritic spines. This testifies to high sensitivity to the ischemic influence of stimulating aditus of pyramidal neurons of layer V in the sensomotor cortex of rat. At 7 days of postischemic damage, dendrites of pyramidal neurone were mostly reduced. The quantitative parameters of dendritic geometry recovered after 30 and 90 days of ischemia.
