Electron microscopic investigation of gap junctions (GJ) on serial sections of rat barrel cortex has shown that GJ were in contact with one or both processes that formed chemical synapses, however, these connections could not traced in single sections. In the serial sections, it was possible to observe two GJ in the immediate proximity to one another, in a single field of vision, thus, each GJ was traced in two or three successive sections in a series. Considering the described variants of GJ arrangement in the cortex, it is suggested that GJ could be a structural basis for local synchronization of the bioelectrical activity not only at postsynaptic, but also at presynaptic level, and the formation of GJ occurs both before, and after the development of chemical synapses.
