Plasticity of morphometrical indicators of central nervous system neural populations at mammals and birds

Neural populations of lateral nuclei of cervical and lumbar department of a spinal cord of sinantrophic and laboratory rodents and neurons population of hyperstriatum of the forebrain of wild and house birds were investigated. Morphometrical indicators – numerical density of cells, sizes of nuclei, cytoplasms, bodies of neurons and structural nuclear-cytoplasmatic factor are revealed. Morphometrical features of motor-neurons of a spinal cord at rodents and neurons hyperstriatum at birds who, possibly, are connected with distinctions phylogenesis, habitats, locomotion and influence of processes of domestication are noted.
