Abstract

The common marmoset (Callithrix jacchus) has been recently developed as a nonhuman primate model useful for studying behaviour, neurology, and higher-level cognitive processes considering their phylogenetic proximity to humans. Here, we investigated the resting-state functional connectivity (RSFC) of the marmoset claustrum, a small, highly connected subcortical structure. Using an open resource of 234 functional MRI scans from awake marmosets, we found claustrum connectivity to the prefrontal cortex, posterior parietal cortex, temporal cortices, cingulate cortex, sensory cortices, limbic areas, basal ganglia, and cerebellum. We also found strong functional connectivity to regions and hubs involved in marmoset resting-state networks. These findings demonstrate marmoset claustrum RSFC similar to previous human and non-human primate studies and validate the integration of marmosets into claustrum research.

狨猴闭孔体静息状态功能连通性。
普通狨猴(Callithrix jacchus)最近被发展为一种非人类灵长类动物模型,用于研究行为、神经学和高级认知过程,考虑到它们与人类的系统发育接近性。在这里,我们研究了绒猴屏状体的静息状态功能连接(RSFC),这是一个小的,高度连接的皮质下结构。利用234个醒着的狨猴功能性MRI扫描的开放资源,我们发现屏状体与前额皮质、后顶叶皮质、颞皮质、扣带皮质、感觉皮质、边缘区、基底神经节和小脑相连。我们还发现,与狨猴静息状态网络相关的区域和枢纽有很强的功能连接。这些发现表明,狨猴闭孔猴RSFC与之前的人类和非人类灵长类动物研究相似,并验证了将狨猴纳入闭孔猴研究的可行性。
