Complex morphofunctional studies of the barrel cortex of the rat identified and analyzed the ultrastructural characteristics of the dendrodendritic electrical synapses — gap junctions (GJ) — of stellate neurons of barrels D2—D3. The local nature of dendrite branching of barrel cells, limited to the volume of the barrel, suggests that these GJ, which account for 7% of all synapses, may be the structural basis of local intrabarrel electrotonic synchronization of pacemaker potentials of barrel neuron hyperpolarization on development of spindle-type activity in the corresponding column.
