The electric organ of mormyrid fishes is composed of action potential-generating cells called electrocytes that together produce a species-typical electric organ discharge (EOD). The electrocytes of mormyrids are disc-shaped cells with distinct anterior and posterior faces, and a series of evaginations of one face that form a stalklike structure that is the site of innervation by spinal electromotoneurons (Bass: J. Comp. Neurol. 244:313-330, '86a). Here, we describe the major ultrastructural… CONTINUE READING
