|March 1, 1978
Abstract:
Perisomatic processes are shown to be temporary morphological formations that appear within 16-28 weeks of embryogenesis, their development being characterized by a certain succession. Perisomatic processes form multiple synaptic complexes with axon endings of unknown origin adherent to perikaryons of pear-shaped neurons. These axon endings are supposed to belong to afferent climbing fibers of cerebellum stimulating differentiation of pear-shaped neurons, localization of these fibers causing a certain succession in the development of perisomatic processes.
