WebAt electrical synapses, unlike chemical synapses, there is a direct physical connection between the presynaptic neuron and the postsynaptic neuron. This connection takes the form of a channel called a gap … WebA gap junction located in neurons is often referred to as an electrical synapse. The electrical synapse was discovered using electrical measurements before the gap junction structure was described.

WebFeb 14, 2024 · Gap junctions contain paired channels in the membranes of the pre and postsynaptic neurons, forming pores. These pores are larger than those of the voltage-gated ion channels in chemical synapses, meaning that a variety of substances can diffuse between the neurons. WebA synapse is the contact site where a neurone and another neurone or a neurone and another cell meet. The presynaptic neurone/cell is the transmitting cell; the postsynaptic neurone/cell is the receiving cell. There are two major types of synapse - electrical and chemical. An electrical synapse is a protein channel called a gap junction, which ...
