Abstract

Background: A common magnitude system-consistently involving the right intraparietal sulcus (IPS)-has been proposed to support the representation of space, time and numerosity. While shared mechanisms are acknowledged, domain-specific contributions have also been suggested. Among these, the role of the right precuneus remains debated, with inconclusive evidence regarding its involvement in spatial and temporal processing. Translating this question into the language domain and within a grounded cognition framework, we investigated the causal contribution of the IPS and precuneus to the processing of spatial and temporal concepts (e.g., circuit, eternity) using a state-dependent Transcranial Magnetic Stimulation (TMS) priming paradigm. Twenty healthy participants received stimulation over the IPS and precuneus, and a sham stimulation over the control site (vertex).

Results: Results showed that stimulation of the IPS abolished the priming effect observed under the sham control condition for both spatial and temporal concepts, whereas stimulation of the precuneus selectively disrupted priming for temporal concepts only.

Conclusions: These findings support the role of the right IPS as a key area for magnitude processing in language, while also highlighting a more specific contribution of the precuneus-particularly its ventral portion-to temporal concepts.

语言中的空间和时间：探索神经重叠和特异性。

背景：一个共同的大小系统一直涉及到右侧顶叶内沟（IPS），已经被提出支持空间、时间和数量的表征。在承认共享机制的同时，也提出了特定领域的贡献。其中，右楔前叶的作用仍然存在争议，没有确凿的证据表明它参与空间和时间处理。将这个问题转化为语言领域，并在一个基础认知框架内，我们使用状态依赖的经颅磁刺激（TMS）启动范式研究了IPS和楔前叶对空间和时间概念（如电路、永恒）处理的因果贡献。20名健康参与者在IPS和楔前叶接受刺激，在对照部位（顶点）接受假刺激。结果：刺激IPS可消除假对照条件下对空间和时间概念的启动效应，而刺激楔前叶可选择性地破坏时间概念的启动效应。结论：这些发现支持了右侧IPS作为语言中量级处理的关键区域的作用，同时也强调了楔前叶——特别是其腹侧部分——对时间概念的更具体贡献。

期刊介绍： A well-established journal in the field of behavioral and cognitive neuroscience, Behavioral and Brain Functions welcomes manuscripts which provide insight into the neurobiological mechanisms underlying behavior and brain function, or dysfunction. The journal gives priority to manuscripts that combine both neurobiology and behavior in a non-clinical manner.
