[Special forms of synaptic junctions in cultures of dissociated mammalian spinal cord and spinal ganglia].
The ultrastructural study of cells in the monolayer culture of dissociated spinal cord and spinal ganglia of mouse embryos has been performed. The results obtained show that in the course of differentiation of completely isolated cells of the spinal cord special forms of synaptic contacts may appear. They are typical of the spinal cord of phylogenetically inferior animal species. These "mixed" synaptic contacts having properties both of electrical and of chemical synapses seem to represent phylogenetically determined processes of synaptogenesis.
