In the era of molecular biology and atomic force microscopy, some important macroscopic issues such as simultaneous bidirectional axonal flow or neuronal multinucleosis remain unaddressed. However, these issues have to be addressed, because they distort the results of our current achievements. Using videorecording technique, we studied adhesive contacts between neurons and their processes and kinetics of anastomosis retraction between the cell bodies up to their complete fusion with introduction of neurites into the cell cytoplasm and formation of binuclear cells. Three proofs refuting the mechanism of binuclearity formation by amitosis are presented. Live trinuclear neurons without signs of amitotic division were identified. Electron microscopy showed that fusion of many living neurons into one simplest during centrifugation of isolated cells.
