The intraparietal sulcus (IPS) is structurally and functionally heterogeneous. We performed a quantitative cyto-/myelo- and receptor architectonical analysis to provide a multimodal map of the macaque IPS. We identified 17 cortical areas, including novel areas PEipe, PEipi (external and internal subdivisions of PEip), and MIPd. Multivariate analyses of receptor densities resulted in a grouping of areas based on the degree of (dis)similarity of their receptor architecture: a cluster encompassing areas located in the posterior portion of the IPS and associated mainly with the processing of visual information, a cluster including areas found in the anterior portion of the IPS and involved in sensorimotor processing, and an ‘intermediate’ cluster of multimodal association areas. Thus, differences in cyto-/myelo- and receptor architecture segregate the cortical ribbon within the IPS, and receptor fingerprints provide novel insights into the relationship between the structural and functional segregation of this brain region in the macaque monkey.

受体驱动的,猕猴顶内沟皮层区域的多模式映射

顶内沟 (IPS) 在结构和功能上是异质的。我们进行了定量的细胞/骨髓和受体结构分析,以提供猕猴 IPS 的多模式图。我们确定了 17 个皮质区域,包括新区域 PEipe、PEipi(PEip 的外部和内部细分)和 MIPd。受体密度的多变量分析导致基于受体结构的(不)相似程度对区域进行分组:一个簇包含位于 IPS 后部的区域,主要与视觉信息的处理相关,一个簇包括在 IPS 前部发现并参与感觉运动处理的区域,以及多模式关联区域的“中间”集群。因此,
