It is known that the regulation of movements is associated with pyramidal neurons of the V layer of the cerebral cortex, axons of which form a pyramidal pathway. In the motor cortex begins, and extrapyramidal system which includes the cerebellum [1, 2].
The study is devoted to histological and morphometric study of pyramidal neurons and Purkinje cells of the motor pathways of the brain of white rats. It is shown that in rats the numerical density of pyramidal neurons of the inner pyramidal layer of the motor cortex (field M1) exceeds the numerical density of these cells of the sensory-motor cortex (field SmI) and Purkinje cells of the ganglionary layer of the cerebellum cortex. At the same time, the area of the cerebellum cortex Purkinje cells is much larger than the area of pyramidal neurons of the motor cortex (field M1) and pyramidal neurons of the sensorimotor cortex (field SmI).
Keywords:morphometry, pyramidal neurons, Purkinje cells, sensorimotor cortex
