Abstract:
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.

The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential.
Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...
