Postnatal morphogenesis of the internal pyramidal neurons of rat neocortex

In present paper, we report for the first time the results of the complex quantitative analysis of the dynamics of post-natal ontogenesis of the internal neocortex pyramid neurons in the rat. There is a progressive growth and differentiation of the neuron’s bodies and neuropil of the internal pyramidal neurons of the rat neocortex, the formation of the structural and metabolic characteristics of their organelles, accompanied by an increase in the immunoreactivity of molecular markers of maturation of these neurons.
