认知神经科学的一个主要目标是识别那些可能由多种认知功能共享的神经计算过程与那些高度特异性的神经计算过程。识别通用函数和专用函数的问题在语言处理领域中是一个特别有趣的问题。在这个领域，事件相关脑电位（ERP）研究表明，在300-700 ms的范围内，左前叶负性（LAN）与句法处理有关。常与语法功能词连在一起。这些词很少或没有语义内容，而是在编码解析所需的句法结构中起作用。在目前的研究中，我们测试了一个假设，即局域网反映了一种更一般的序列处理能力的运作，其中特殊符号编码结构信息，当与序列中的过去元素结合时，可以预测后继元素。我们在非语言排序任务中记录了erp，该任务要求受试者（n = 10）处理具有上述功能属性的特殊符号。与控制条件下的erp相比。功能符号处理引起的时间和空间特征之间的左前侧负移与语言功能词处理中描述的LAN非常相似，支持我们的假设。这些结果在句法和认知序列加工的相关研究背景下进行了讨论。《神经病学杂志》（英文版），2000。
A major objective of cognitive neuroscience is to identify those neurocomputational processes that may be shared by multiple cognitive functions vs those that are highly specific. This problem of identifying general vs specialized functions is of particular interest in the domain of language processing. Within this domain, event related brain potential (ERP) studies have demonstrated a left anterior negativity (LAN) in a range 300-700 ms, associated with syntactic processing. often linked to grammatical function words. These words have little or no semantic content, but rather play a role in encoding syntactic structure required for parsing. In the current study we test the hypothesis that the LAN reflects the operation of a more general sequence processing capability in which special symbols encode structural information that, when combined with past elements in the sequence, allows the prediction of successor elements. We recorded ERPs during a non-linguistic sequencing task that required subjects (n = 10) to process special symbols possessing the functional property defined above. When compared to ERPs in a control condition. function symbol processing elicits left anterior negative shift between temporal and spatial characteristics quite similar to the LAN described during function word processing in language, supporting our hypothesis. These results are discussed in the context of related studies of syntactic and cognitive sequence processing. NeuroReport 11:3187-3191 (C) 2000 Lippincott Williams & Wilkins.
