What is an electrical synapse?

(N/A) In an electrical synapse,the membranes of pre-synaptic and post-synaptic neurons are in very close proximity.
Electrical current can flow directly from one neuron into the other across these synapses.
Transmission of an impulse across electrical synapses is very similar to impulse conduction along a single axon.
Impulse transmission across an electrical synapse is always faster than that across a chemical synapse.
Electrical synapses are rare in the human nervous system.
