Abstract

While portions of the mammalian olfactory system have been studied extensively, the anterior olfactory nucleus (AON) has been relatively ignored. Furthermore, the existing research is dispersed and obscured by many different nomenclatures and approaches. The present review collects and assembles the relatively sparse literature regarding the portion of the brain situated between the olfactory bulb and primary olfactory (piriform) cortex. Included is an overview of the area's organization, the functional, morphological and neurochemical characteristics of its cells and a comprehensive appraisal of its efferent and afferent fiber systems. Available evidence suggests the existence of subdivisions within the AON and demonstrates that the structure influences ongoing activity in many other olfactory areas. We conclude with a discussion of the AON's mysterious but complex role in olfactory information processing.

摘要

虽然哺乳动物嗅觉系统的某些部分已得到广泛研究，但前嗅核（AON）相对受到忽视。此外，现有研究分散，且因众多不同的命名法和方法而变得模糊不清。本综述收集并整理了关于位于嗅球和初级嗅觉（梨状）皮质之间的脑区的相对稀少的文献。内容包括该区域的组织概述、其细胞的功能、形态和神经化学特征，以及对其传出和传入纤维系统的全面评估。现有证据表明AON内存在细分，并证明该结构影响许多其他嗅觉区域的持续活动。我们最后讨论了AON在嗅觉信息处理中神秘但复杂的作用。
