Abstract

When the goldfish Mauthner cell fires an impulse there is a simultaneous hyperpolarization of adjacent medullary neurons as far as 200 micrometers from its soma. This hyperpolarization is due to an inward transmembrane flow of some of the current generated by the Mauthner cell spike and is sufficiently large to block spikes evoked both directly or transsynaptically.
