How is an impulse transmitted across electrical synapses?

How is an impulse transmitted across electrical synapses?
  1. By opening ion channels
  2. By generating a new potential
  3. By flowing directly from one neuron to another
  4. By binding to specific receptors

Solution

At electrical synapses, the membranes of pre- and post-synaptic neurons are in close proximity, allowing electrical current to flow directly from one neuron into the other across these synapses. Transmission of an impulse across electrical synapses is similar to impulse conduction along a single axon.
