Electrical impulses don't run through the human body like electricity through wires. The neuron will play with its charge so that it will release a chemical neurotransmitter on the other side. The neurotransmitter will move to the next neuron which will in turn, play with its electrical charge so that it can release a neurotransmitter to next neuron.

Essentially it's a relay race, so unless it's stated to be lightning release, it should be presumed not to be.
