Book Chapter Description

Electrogenesis is based on the differentiation of excitable cells of neural or muscular lineage into electrogenic units. Neural electrocytes are enlargements of spinal electromotor axons lacking a peripheral target. Myogenic electrocytes are excitable syncitia derived from muscle fibers that lack contractile machinery. The synchronous activation of an orderly array of parallel excitable membrane patches generates relatively large electric fields of stereotyped waveform. These fields are used by the fish either as a weapon or as a carrier of information. In organs localized to a small region, the species-specific waveform of the discharge is determined by effector responses. In organs extended throughout the body, a neural network accounts for the coordination of electrocyte activity for generating the species-specific waveforms of the discharge.
