The processing mechanism of verbs-actions and nouns-objects is a central topic of language research, with robust evidence for behavioral dissociation. The neural basis for these two major word and/or conceptual classes, however, remains controversial. Two experiments were conducted to study this question from the network perspective. Experiment 1 found that nodes of the same class, obtained through task-evoked brain imaging meta-analyses, were more strongly connected with each other than nodes of different classes during resting-state, forming segregated network modules. Experiment 2 examined the behavioral relevance of these intrinsic networks using data from 88 brain-damaged patients, finding that across patients the relative strength of functional connectivity of the two networks significantly correlated with the noun-object vs. verb-action relative behavioral performances. In summary, we found that verbs-actions and nouns-objects are supported by separable intrinsic functional networks and that the integrity of such networks accounts for the relative noun-object- and verb-action-selective deficits.
动词（动作）和名词（物体）的加工机制是语言研究的核心主题，有充分的行为分离证据。然而，这两类主要词汇和/或概念范畴的神经基础仍存在争议。进行了两项实验从网络角度研究这个问题。实验1发现，通过任务诱发脑成像元分析获得的同一类节点在静息状态下彼此之间的连接比不同类节点更强，形成了分离的网络模块。实验2使用来自88名脑损伤患者的数据检验了这些内在网络的行为相关性，发现 across patients（此处across patients表述有误，可能是“across all patients”，译为“在所有患者中”）这两个网络功能连接的相对强度与名词 - 物体和动词 - 动作的相对行为表现显著相关。总之，我们发现动词（动作）和名词（物体）由可分离的内在功能网络支持，并且这些网络的完整性解释了相对的名词 - 物体和动词 - 动作选择性缺陷。
