In an electrical synapse, how is the nerve impulse transmitted between neurons?
1. By releasing neurotransmitters across the synaptic cleft
2. Through the direct movement of ions via gap junctions
3. By synaptic vesicles fusing with the postsynaptic membrane
4. Through saltatory conduction at the nodes of Ranvier.
