In lateral line and electrosensory systems of fish, the animal's own movements create unwanted stimulation that could interfere with the detection of biologically important signals. Here we report that an adaptive filter in the medullary nuclei of both senses suppresses self-stimulation. Second-order electrosensory neurons in an elasmobranch fish and mechanosensory neurons in a teleost fish learn to cancel the effects of stimuli that are presented coupled to the fish's movements. A model is proposed for how the adaptive filter is realized by the cerebellar-like circuits of the hindbrain nuclei in these senses.
在鱼类的侧线和电感应系统中，动物自身的运动会产生不必要的刺激，这可能会干扰对生物学重要信号的检测。在此我们报告，这两种感觉的延髓核中的一种自适应滤波器可抑制自我刺激。一条软骨鱼中的二阶电感应神经元和一条硬骨鱼中的机械感应神经元学会抵消与鱼类运动相关的刺激的影响。针对这些感觉中后脑核的类小脑回路如何实现自适应滤波器，我们提出了一个模型。
