  1. 1.

    Electric organ discharges (EOD) were measured in a wave-type electric fish,Apteronotus, with an array of electrodes.

  2. 2.

    The EOD waveform observed in the transient area (area where the equipotential lines converged) was a triphasic one in comparison to a biphasic one in the rest of the area. Electronic circuit simulation suggested that the triphasic waveform resulted from incomplete electrocyte synchronization within the electric organ.

  3. 3.

    The EOD field was obtained by computer simulation using the finite-element-method. The simulated results were used for calculation of the transepidermal potential difference distribution. This distribution is discussed with respect to sensitivity differences of electroreceptors in various parts of the fish.
