Conditioning experiments revealed that Proteus perceives a back-and-forth moving (approximately 1 Hz) direct-current field and its polarity. Minimum behavioral thresholds occurred at a current density of 0.15 microA/cm2, corresponding to a voltage gradient of 0.5 mV/cm. Recordings from afferent nerve fibers showed that ampullary electroreceptors in Proteus respond as do other nonteleost receptors, i.e. with an increase in discharge rate to cathodal current and a decrease to anodal current (threshold: approximately 1 mV/cm).
条件实验表明，盲鳗能感知来回移动（约1赫兹）的直流电场及其极性。行为阈值最小值出现在电流密度为0.15微安/平方厘米时，对应电压梯度为0.5毫伏/厘米。对传入神经纤维的记录显示，盲鳗的壶腹电感受器与其他非硬骨鱼感受器的反应方式相同，即阴极电流时放电率增加，阳极电流时放电率降低（阈值：约1毫伏/厘米）。
