Sixteen healthy subjects took part in this event-related potentials (ERPs) study aimed at investigating the neural response of the taste-visual cross-modal pairing. An interference effect was observed at the behavioral level: the mismatched condition was performed more slowly than the matched condition. ERP analyses revealed a more negative component between 400 and 600 ms in the mismatched condition than in the matched condition. Dipole source analysis of the difference wave (mismatched minus matched) indicated that two generators localized in prefrontal cortex (PFC) and posterior cingulate cortex (PCC) contributed to this cross-modal interference effect. These results provided the electrophysiological evidence of interference during the extraction of taste information from memory and conflict control during the incongruent taste-visual information processing.
十六名健康受试者参与了这项事件相关电位(ERP)研究,旨在研究味觉-视觉跨模态配对的神经反应。在行为水平上观察到干扰效应:不匹配条件的反应速度比匹配条件慢。ERP 分析显示,在不匹配条件下,400 到 600 毫秒之间的成分比在匹配条件下更负。差异波(不匹配减去匹配)的偶极子源分析表明,两个位于前额叶皮层(PFC)和后扣带皮层(PCC)的发生器对这种跨模态干扰效应有贡献。这些结果提供了从记忆中提取味觉信息过程中干扰以及不一致的味觉-视觉信息处理过程中冲突控制的电生理证据。
