Precision estimates of network organization from functional connectivity MRI in the human and tract-tracing data in the marmoset monkey converge to reveal an orderly macroscale gradient of sequential networks across the cerebral cortex. Parallel networks begin with a sequence of multiple nested sensory-motor networks in both species progressing to more distributed association networks in rostral prefrontal and temporal association zones, which are expanded and differentiated in the human. From this perspective, the spatially-distributed motif encountered in association networks appears to be on a continuum with primary sensory-motor networks. Network motifs supporting sophisticated forms of human cognition may arise from specializations of distributed anatomical networks formed in an ancestor at least 45 million years ago.
来自人类功能连接性磁共振成像和狨猴神经束示踪数据的网络组织精确估计结果趋于一致，揭示了跨大脑皮层的顺序网络存在有序的宏观梯度。在这两个物种中，并行网络均始于一系列多个嵌套的感觉运动网络，进而发展为前额叶和颞叶联合区中分布更广的联合网络，而这些联合网络在人类中得到了扩展和分化。从这个角度来看，联合网络中遇到的空间分布式基序似乎与初级感觉运动网络处于连续统一体上。支持复杂人类认知形式的网络基序可能源于至少4500万年前一个祖先中形成的分布式解剖网络的特化。
