Humans can reason about other minds, comprehend language and imagine. These abilities depend on association regions that exhibit evolutionary expansion and prolonged postnatal development. Precision maps within individuals reveal these expanded zones are populated by multiple specialized networks that each possess a spatially distributed motif but remain anatomically separated throughout the cortex for language, social and mnemonic / spatial functions. Rather than converge on multi-domain regions or hubs, these networks include distinct regions within rostral prefrontal and temporal association zones. To account for these observations, we propose the expansion-fractionation-specialization (EFS) hypothesis: evolutionary expansion of human association cortex may have allowed for an archetype distributed network to fractionate into multiple specialized networks. Human development may recapitulate fractionation and specialization when these abilities emerge.

并行分布式关联网络的精确估计:领域专业化的证据和对进化和发展的影响。

人类可以推理其他思想,理解语言和想象。这些能力取决于表现出进化扩张和延长出生后发育的关联区域。个体内部的精确地图显示,这些扩展区域由多个专门的网络组成,每个网络都具有空间分布的主题,但在整个皮层中保持解剖学上的分离,用于语言、社交和记忆/空间功能。这些网络不是集中在多域区域或枢纽上,而是包括喙前额叶和时间关联区域内的不同区域。为了解释这些观察结果,我们提出了扩展-分数-专业化 (EFS) 假设:人类关联皮层的进化扩展可能允许原型分布式网络分成多个专门的网络。当这些能力出现时,人类发展可能会概括分馏和专业化。
