Abstract

In Chapter 2, were mentioned some of the ways by which neurons can communicate with each other, including chemical transmission via synapses and direct electrical connections through gap junctions, but there are other possibilities. Here, we consider coupling of individual impulses through their external current loops. This is called ephaptic coupling (as opposed to synaptic), from a Greek verb meaning “to touch.”
