    Abstract:
    Some characteristics of the structure of locomotor fields 44 and 45, and of the cortical fields 4 and 6 of the motor analyzer in the left and the right hemispheres of the human brain were studied. The study revealed statistically significant differences between some of the characteristics. The index of the vertical arrangement of the pyramidal neurons in layer III of fields 44 and 45, as well as field 6 were greater in the left hemisphere than in the right one. The size of the profile field of Betz's cells in field 4, and of the large pyramidal neurons in layer III of field 6 were greater also in the left hemisphere in two brains out of 4, and showed no differences in the other 2. The size of the profile fields of the pyramidal neurons in layer III of fields 44 and 45 was much greater in the left hemisphere in all the cases.
