感觉系统使动物能够生成环境的表征。许多水生脊椎动物共有的一种感觉系统是侧线。本章回顾了外周侧线系统的功能组织，并描述了称为神经丘的感觉结构的组织和分布、它们的神经支配模式以及它们的传入神经支配与大脑中传入终止位点之间的关系。它详细介绍了侧线传入神经元对信息的编码如何划分为子模态，并总结了它们各自的刺激维度和响应动态，包括频率选择性和阈值敏感性。作者进一步讨论了能够检测鱼体内局部和整体水扰动的感受野、空间选择性和方向选择性。最后，介绍了各种自然水动力刺激的外围编码的知识现状，例如大规模环境水运动、偶极场、平移物体和表面波。
Sensory systems enable animals to generate a representation of the environment. One sensory system common to many aquatic vertebrates is the lateral line. This chapter reviews the functional organization of the peripheral lateral line system and describes the organization and distribution of the sensory structures termed neuromasts, their innervation patterns, and the relationship between their afferent innervation and the afferent termination sites in the brain. It details how neuronal encoding of information by lateral line afferents is partitioned in submodalities and summarizes their respective stimulus dimensions and response dynamics including frequency selectivity and threshold sensitivity. The authors further discuss the receptive fields, spatial selectivity, and the directional selectivity that enables the detection of local and global water disturbances across the fish body. Finally the current state of knowledge on peripheral encoding of various natural hydrodynamic stimuli such as large scale ambient water motions, dipole fields, translating objects, and surface waves are presented.
