The dorsal cochlear nucleus (DCN) integrates auditory and multisensory signals at the earliest levels of auditory processing. Proposed roles for this region include sound localization in the vertical plane, head orientation to sounds of interest, and suppression of sensitivity to expected sounds. Auditory and non-auditory information streams to the DCN are refined by a remarkably complex array of inhibitory and excitatory interneurons, and the role of each cell type is gaining increasing attention. One inhibitory neuron that has been poorly appreciated to date is the superficial stellate cell. Here we review previous studies and describe new results that reveal the surprisingly rich interactions that this tiny interneuron has with its neighbors, interactions which enable it to respond to both multisensory and auditory afferents.
背侧耳蜗核（DCN）在听觉处理的最早阶段整合听觉和多感觉信号。该区域的建议作用包括在垂直平面上定位声音、将头部定向到感兴趣的声音以及抑制对预期声音的敏感性。听觉和非听觉信息流到 DCN 被一系列非常复杂的抑制性和兴奋性中间神经元进行了细化，并且每种细胞类型的作用都越来越受到关注。迄今为止，一种被低估的抑制性神经元是浅层星状细胞。在这里，我们回顾了以前的研究，并描述了新的结果，这些结果揭示了这个微小的中间神经元与其邻居之间惊人丰富的相互作用，这些相互作用使其能够对多感觉和听觉传入做出反应。
