[Interpretation of some mechanisms of evolution neuromorphogenesis with aid of experiments in culture of neurons].
Based on study of culture of isolated neurons of molluscs Lymnaea stagnalis, elementary mechanisms of motility of living neurons have been analyzed. With aid of these studies, an attempt is made at explaining mechanisms of the chief cellular morphogenetic processes of evolution of simple nervous systems: exit of neuroepithelial cells from the layer of external epithelium, transformation of sensory bipolar cells into the associative ones, migration of neurons, formation of diffuse plexus and its conversion into the plexus-ganglionary system, regularities of formation of ganglia and synganglia. Use of the culture of dissociated neurons is characterized as a novel direction of evolutionary neuromorphology.
