Abstract
Based on our own data on generation of spindle-like field electrical activity in neuronal barrels of the rat somatic cortex and also on the published data on the properties of voltage-dependent channels in the membranes of cortical cells, we developed a model of the ensemble (simple network) of neurons connected by electrical synapses. Such connections were found earlier in neurophysiological and ultramicroscopic studies. Model neurons with membranes having sodium, potassium, and calcium channels described in the literature were capable of generating bursting rhythmic impulse activity under conditions of switching off of synaptic connections between cells (isolation). With switching on of electrical synapses, spiking generated by separate neurons, which initially was nonsynchronous, became synchronized in time. Ipso facto, we demonstrated the ability of pacemaker oscillatory activity to be electrotonically synchronized in ensembles of neurons connected with electrical synapses.
