Water currents are extremely important in the aquatic environment and play a very significant role in the lives of fishes. Sensory processing of water currents involves a number of sensory modalities including the inner ear, vision, tactile sense and the mechanosensory lateral line. The inner ear will detect whole-body accelerations generated by changes in flow, or by turbulence, whereas visual and tactile inputs will signal translational movement with respect to an external visual or tactile reference frame. The superficial neuromasts of the mechanosensory lateral line detect flow over the surface of the body and have the appropriate anatomical distribution and physiological properties to signal the strength and the direction of flow and, hence, contribute to the detection of regional differences in flow over different parts of the body.
水流在水生环境中极其重要，对鱼类的生命起着非常重要的作用。对水流的感觉处理涉及多种感觉方式，包括内耳、视觉、触觉和机械感觉侧线。内耳会检测由水流变化或湍流产生的全身加速度，而视觉和触觉输入会以外部视觉或触觉参考系为参照发出平移运动的信号。机械感觉侧线的表面神经丘检测身体表面的水流，具有适当的解剖分布和生理特性，能够发出水流强度和方向的信号，从而有助于检测身体不同部位水流的区域差异。
