[Syncytial coupling of neurons in tissue culture and in early ontogenesis].
The formation syncytial coupling between the processes of different neurons in neuron culture was demonstrated with the help of computer time-lapse video recording. It was shown that the processes of one neuron that established the connection with the other neuron, did not undergo Wallerian degeneration after the death of their cell body (their trophic center). For several hours it was possible to observe the translocation of cytoplasmic varicosity along the branches from one neuron to another. Electron microscopy of neuronal processes of the intramural myenteric plexus cells in the early postnatal period, demonstrated all the transitional stages from the fusion and perforation of plasma membranes of axons in contact till complete coalescence of neuroplasm of cell processes with the formation of residual membranous structures in the region of former intercellular membrane contact.
