本研究结合体表和脑内脑电(EEG)研究了阅读过程中情绪信息处理的时空脑动力学。两种不同的理论观点是对立的。根据标准的心理语言学观点，对单词的情感反应是在语义激活之后在阅读网络本身内产生的。根据神经再利用的观点，参与处理其他刺激(脸、图片、气味)中包含的情绪信息的大脑区域可能也负责处理文字中的情绪信息。我们专注于一种特定的情绪--厌恶--它在大脑的前脑岛有一个明确的轨迹。表面脑电早在200ms时就显示出厌恶词和中性词的差异。来源定位提示情绪效应在左前岛的皮质产生。这些发现通过两名癫痫患者的颅内记录得到证实，这些患者在岛区和眼眶额区使用深度电极。早在200ms时，两个电极就表现出了厌恶阅读的效果。大脑区域(脑岛)的早期情绪效应对各种情况和刺激下的特定情绪做出反应，显然挑战了支持神经重复使用视角的经典顺序阅读理论。
This study investigates the spatiotemporal brain dynamics of emotional information processing during reading using a combination of surface and intracranial electroencephalography (EEG). Two different theoretical views were opposed. According to the standard psycholinguistic perspective, emotional responses to words are generated within the reading network itself subsequent to semantic activation. According to the neural re-use perspective, brain regions that are involved in processing emotional information contained in other stimuli (faces, pictures, smells) might be in charge of the processing of emotional information in words as well. We focused on a specific emotion-disgust-which has a clear locus in the brain, the anterior insula. Surface EEG showed differences between disgust and neutral words as early as 200 ms. Source localization suggested a cortical generator of the emotion effect in the left anterior insula. These findings were corroborated through the intracranial recordings of two epileptic patients with depth electrodes in insular and orbitofrontal areas. Both electrodes showed effects of disgust in reading as early as 200 ms. The early emotion effect in a brain region (insula) that responds to specific emotions in a variety of situations and stimuli clearly challenges classic sequential theories of reading in favor of the neural re-use perspective.
