[Features of the development of the dendrites of differentiating pyriform cerebellar cortex neurons in mammals and man].

Pecularities of development of the differentiating piriform neuron cerebellum cortex dendrite system in the mammals and in man were studied with light and electron microscopy. Three consequent stages are involved in the process: the formation of a dilated portion of apical (supranuclear) cytoplasm with an increased amount of organelles; the formation of a temporary apical cytoplasmic mitre (cone); the development of the dendrite system occurring on the background of reduction of this temporary cytoplasmic formation. In the course of differentiation, a distinct change of the dendrite cytoplasm contents from reticular to tubular ones takes place.
