使用脑磁图测量阅读现有衍生德语形容词（如freundlich， friendly）时的神经元激活，并与阅读不存在但语义同义的形容词（*freundhaft）和阅读不存在、语义和形态异常的形容词（*freundbar）时的神经元激活进行比较。通过应用分布式源模型，我们发现在N400的时间范围内，左侧颞叶区域内的神经元活动逐渐增加。活动从存在的同义词增加到反常的形容词。强调使用神经生理学测量，这些结果表明，形态语义分析发生在不存在的形态复杂的假词，即使没有当前任务的保证。此外，这些数据支持形态分解。2009爱思唯尔爱尔兰有限公司版权所有。
Neuronal activation as response to reading existing derived German adjectives (e.g., freundlich, friendly) was measured using MEG and compared to that evoked by non-existing, but semantically synonymous adjectives (*freundhaft) and to activation induced by non-existing, semantically and morphologically anomalous adjectives (*freundbar). By applying distributed source modeling we revealed a gradual increase of neuronal activity within areas of the left temporal lobe in the time range of the N400. Activity increased from existing over synonymous to anomalous adjectives. Underscoring the use of neurophysiological measures, these results demonstrate that morpho-semantic analysis take place for non-existing morphologically complex pseudowords even if not warranted by the current task. Furthermore, these data argue in favor of morphological decomposition. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
