 If the electrocyte has sodium channels on both sides, the depolarization caused by firing action potentials on one side of the electrocyte can cause the sodium channels on the other side of the electrocyte to fire as well.In most fishes, electric organs are oriented to fire along the length of the body, usually lying along the length of the tail and within the fish's musculature, with smaller accessory electric organs in the head.However, there are some exceptions; in stargazers and in rays the electric organs are oriented along the dorso-ventral (up-down) axis.
