Electroplaques

Electrocytes or electroplaques are cells used by electric eels and other electric fishes for electrogenesis, used to generate an electric shock, but also for electroreception. They are flat disk-like cells that are stacked in a sequence in a manner similar to a battery, and make up the electric organs of the fish. Electric eels have several thousand of these stacked, each producing 0.15V, this becomes a lot when you add them together. Postsynaptically electrocytes work much like muscle cells, and because of its resemblance to nerve-muscle junctions, it's used in research to model important components of this. To discharge the electrocytes at the correct time, the electric eel uses its pacemaker nucleus , a nucleus of pacemaker neurons . When an electric eel spots its prey, the pacemaker neurons fires and acetylcholine is soon released from electromotor neurons to the electrocytes, resulting in an electric organ discharge.
