How does impulse transmission occur across electrical synapses?

How does impulse transmission occur across electrical synapses?
  1. By the release of neurotransmitters
  2. By the flow of direct electrical current
  3. By the transmission of magnetic fields
  4. By the transmission of electrical impulses along a single axon

Solution

At electrical synapses, the membranes of pre- and post-synaptic neurons are in very close proximity, allowing for the flow of direct electrical current from one neuron into the other.
