目前灵长类动物听觉皮层的工作模型是根据对新大陆和旧大陆猴子的大量研究构建的。它包括三个层次的处理。一个主要的水平，核心区，围绕中间和横向的次要带区。第三个加工水平，parabelt区域，位于带的侧面。绒猴（Callithrix jacchus jacchus）是研究听觉加工的重要模型系统，但其解剖结构尚未完全建立。在以前的研究中，我们主要关注核心区和内侧带区的结构和连接。在目前的研究中，在绒猴的侧带和parabelt的皮质皮质连接进行了检查。将示踪剂注入侧带和parabelt的吻侧和尾侧部分。这两个地区揭示了地形连接沿着rostrocaudal轴，其中尾部地区的注射有较强的连接与尾部地区，和吻侧地区的注射。侧带与核心、带和副带有较强的联系，而副带与带有较强的联系，但与核心没有联系。来自副脑带中注射的核心中的标记显著减少或不存在，这与副脑带主要依赖于其皮质输入的想法一致。此外，目前和以前的研究表明，与其他灵长类动物中观察到的一致，在绒猴解剖组织的层次原则。
The current working model of primate auditory cortex is constructed from a number of studies of both New and Old World monkeys. It includes three levels of processing. A primary level, the core region, is surrounded both medially and laterally by a secondary belt region. A third level of processing, the parabelt region, is located lateral to the belt. The marmoset monkey (Callithrix jacchus jacchus) has become an important model system to study auditory processing, but its anatomical organization has not been fully established. In previous studies, we focused on the architecture and connections of the core and medial belt areas. In the current study the corticocortical connections of the lateral belt and parabelt were examined in the marmoset. Tracers were injected into both rostral and caudal portions of the lateral belt and parabelt. Both regions revealed topographic connections along the rostrocaudal axis, where caudal areas of injection had stronger connections with caudal areas, and rostral areas of injection with rostral areas. The lateral belt had strong connections with the core, belt and parabelt, whereas the parabelt had strong connections with the belt but not the core. Label in the core from injections in the parabelt was significantly reduced or absent, consistent with the idea that the parabelt relies mainly on the belt for its cortical input. In addition, the present and previous studies indicate hierarchical principles of anatomical organization in the marmoset that are consistent with those observed in other primates.
