Abstract

Determining the neural bases of basic linguistic composition is central to research on the cognitive neuroscience of language. The left anterior temporal lobe (LATL) is widely reported during linguistic composition of visual stimuli in magnetoencephalography (MEG) studies. However, this effect is less reported during the linguistic composition of auditory stimuli in intracranial electroencephalography (iEEG) studies. To further test this discrepancy, we directly examined the composition effect in LATL by combining the iEEG technique with visual stimuli. Participants were asked to read minimal two-word phrases in the composition condition and read words preceded by pound signs in the noncomposition condition. The results showed that high-gamma power in the LATL was higher in the composition condition compared to the noncomposition condition. These results provide more substantial evidence for the role of LATL in basic linguistic composition (at least in visual modality) and highlight the potential role of stimuli modality (visual vs. auditory) in the phrasal composition effect in LATL.

左前颞叶在基本语言构成中的作用：来自立体脑电图的证据。

确定基本语言构成的神经基础是语言认知神经科学研究的核心。在脑磁图（MEG）研究中，左侧颞叶（LATL）在视觉刺激的语言构成中被广泛报道。然而，在颅内脑电图（iEEG）研究中，这种影响在听觉刺激的语言组成中较少报道。为了进一步验证这种差异，我们将iEEG技术与视觉刺激相结合，直接检查了LATL的构成效应。参与者被要求在写作条件下阅读最少的两个单词的短语，在非写作条件下阅读前面有磅号的单词。结果表明，与非复合条件相比，复合条件下LATL的高伽马功率更高。这些结果为LATL在基本语言构成中的作用（至少在视觉情态上）提供了更有力的证据，并突出了刺激情态（视觉与听觉）在LATL短语构成效应中的潜在作用。
