Ultrastructural transformations of axo-somatic and axo-dendritic synapses of the rabbit sensorimotor cortex were studied during: 1) polarization of the cortical surface with a DC anode and 2) the setting up of a polarization motor dominant. A comparison between the structural characteristics of the examined region of the cerebral cortex of the two groups of animals revealed transformations in the synaptic apparatus, which may be regarded as a result of the formation of a temporary connection: an increase in the number of axo-dendritic synapses with considerably thickened postsynaptic membranes; an increase in the number of axonic terminals with a concentration of synaptic vesicles and mitochondria content. The indicated changes were more pronounced in the deep layers of the sensorimotor cortex. |
