Gap junctions chemical synapses

WebChemical synapses and gap junction-mediated electrical synapses are two types of synaptic connections that regulate information processing and flow in the nervous system. Electrical synapses play an important role in coupling neuronal activities and defective gap junctions are associated with neurological diseases. WebThe mode of neurotransmission in electrical synapses is quite different from that in chemical synapses. In an electrical synapse, the presynaptic and postsynaptic membranes are very close together and are actually physically connected by channel … Sometimes a single EPSP is strong enough to induce an action potential in the …
