Since its designation in 1896 as a putative olfactory structure, the olfactory tubercle has received little attention in terms of elucidating its role in the processing and perception of odors. Instead, research on the olfactory tubercle has mostly focused on its relationship with the reward system. Here we provide a comprehensive review of research on the olfactory tubercle-with an emphasis on the likely role of this region in olfactory processing and its contributions to perception. Further, we propose several testable hypotheses regarding the likely involvement of the olfactory tubercle in both basic (odor detection, discrimination, parallel processing of olfactory information) and higher-order (social odor processing, hedonics, multi-modal integration) functions. Together, the information within this review highlights an understudied yet potentially critical component in central odor processing.
自 1896 年被指定为一个假定的嗅觉结构以来,嗅结节在阐明其在气味处理和感知中的作用方面几乎没有得到关注。相反,对嗅结节的研究主要集中在它与奖励系统的关系上。在这里,我们提供了一个关于嗅结节的综合研究综述,重点是该区域在嗅觉处理中的可能作用及其对感知的贡献。此外,我们提出了几个关于嗅结节在基本功能(气味检测、辨别、嗅觉信息的并行处理)和更高阶功能(社交气味处理、快感、多模态整合)中可能参与的可测试假设。总的来说,本综述中的信息突出了一个在中枢气味处理中尚未得到充分研究但具有潜在重要性的组成部分。
