Fig. 4. The electric organ discharge (EOD) current shunted in a particular phase of the EOD can be predicted from the modulation recorded during maintained switch closure. The oscillogram shows accumulated recordings of a set of current signals recorded as the switch was closed briefly for 100 µs during various phases of the EOD and the current recorded during prolonged switch closure lasting for the whole EOD (continuous trace). The peaks of the brief current signals retrace the continuous curve recorded during maintained switch closure.
