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.
采用 MEG 测量了对阅读现有派生德语形容词（如 freundlich，友好）的神经激活情况，并将其与不存在但语义上同义的形容词（*freundhaft）以及不存在且语义和形态异常的形容词（*freundbar）所引起的激活进行了比较。通过应用分布式源建模，我们在 N400 的时间范围内揭示了左颞叶区域内神经元活动的逐渐增加。活性从现有形容词增加到同义形容词，再增加到异常形容词。这些结果强调了神经生理测量的应用，证明即使当前任务不需要，也会对不存在的形态复杂的伪词进行形态语义分析。此外，这些数据支持形态分解。
