In numerous peripheral sense organs, external stimuli are detected by primary sensory neurons compartmentalized within specialized structures composed of cuticular or epithelial tissue. Beyond reflecting developmental constraints, such compartmentalization also provides opportunities for grouped neurons to functionally interact. Here, the authors review and illustrate the prevalence of these structural units, describe characteristics of compartmentalized neurons, and consider possible interactions between these cells. This article discusses instances of neuronal crosstalk, examples of which are observed in the vertebrate tastebuds and multiple types of arthropod chemosensory hairs. Particular attention is paid to insect olfaction, which presents especially well‐characterized mechanisms of functional, cross‐neuronal interactions. These examples highlight the potential impact of peripheral processing, which likely contributes more to signal integration than previously considered. In surveying a wide variety of structural units, it is hoped that this article will stimulate future research that determines whether grouped neurons in other sensory systems can also communicate to impact information processing.

神经元区室化：在信息处理的最早阶段整合感觉输入的方法？
在许多外周感觉器官中，外部刺激由初级感觉神经元检测到，初级感觉神经元划分在由角质层或上皮组织组成的特殊结构内。除了反映发育限制之外，这种划分还为分组神经元进行功能性相互作用提供了机会。在这里，作者回顾并说明了这些结构单元的普遍性，描述了区室化神经元的特征，并考虑了这些细胞之间可能的相互作用。本文讨论了神经元串扰的实例，例如在脊椎动物味蕾和多种节肢动物化学感应毛发中观察到的例子。特别关注昆虫嗅觉，它呈现出功能性、跨神经元相互作用的特别明确的机制。这些例子凸显了外围处理的潜在影响，外围处理对信号集成的贡献可能比之前认为的更大。在调查各种结构单元时，希望本文能够激发未来的研究，以确定其他感觉系统中的分组神经元是否也可以进行通信以影响信息处理。
