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 ... 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 proteins forming gap junctions. Gap junctions allow current to pass directly from one …
