Electric organ (biology) in research because of their resemblance to nerve-muscle junctions. The stack of electrocytes has long been compared to a voltaic pile, and may even have inspired the invention of the battery, since the analogy was already noted by Alessandro Volta. While the electric organ is structurally similar to a battery, its cycle of operation is more like a Marx generator, in that the individual elements are slowly charged in parallel, then suddenly and nearly simultaneously discharged in series to produce a high voltage pulse. To discharge the electrocytes at the correct time, the electric eel uses its pacemaker nucleus, a
