在攻击和求偶的情况下，本征反复中断其电器官放电（EOD）。这些中断（图 1）包含低频分量和高频瞬变，因此分别刺激壶腹和结节电感受器（图 2、3）。这两类受体提供的信息沿着不同的路径传递，通过后脑的电感觉侧线叶（ELL），到达中脑的背侧半圆环（TSd）。环面的一些神经元接收来自两种类型受体的输入（图 14、15），而一些神经元主要对 EOD 中断做出反应，而对其他形式的信号调制相当不敏感（图 12、13）。这种高选择性似乎是由于来自个体选择性较低的神经元的输入的收敛和门控造成的。
In the context of aggression and courtship,Eigenmanniarepeatedly interrupts its electric organ discharges (EODs) These interruptions (Fig. 1) contain low-frequency components as well as high-frequency transients and, therefore, stimulate ampullary and tuberous electroreceptors, respectively (Figs. 2, 3). Information provided by these two classes of receptors is relayed along separate pathways, via the electrosensory lateral line lobe (ELL) of the hindbrain, to the dorsal torus semicircularis (TSd) of the midbrain. Some neurons of the torus receive inputs from both types of receptors (Figs. 14, 15), and some respond predominantly to EOD interruptions while being rather insensitive to other forms of signal modulations (Figs. 12, 13). This high selectivity appears to result from convergence and gating of inputs from individually less selective neurons.
