ABSTRACT

Introduction Electroreceptive sh detect nearby objects by processing the information contained in the pattern of electric currents through the skin. In weakly electric sh, these currents result from a self-generated eld, produced by the electric organ discharge (EOD). Local transepidermal voltage or current density is the eective stimulus for electroreceptors. e distribution of voltage or current on the sensory surface of the sh’s skin is the electric image of the surrounding environment [1-3]. From this image, the brain constructs a representation of the external world. erefore, to understand electrolocation it is necessary to know the imagegeneration strategy used by electrolocating animals.
