Abstract

Our understanding of the neural correlates of crossmodal binding in the human brain derives almost exclusively from studies of audition, vision and somatosensation. A new study by Gottfried and Dolan extends our understanding of multisensory integration by showing that facilitation of odor detection by visual cues depends on object congruency, as well as on enhanced activity in the superior temporal sulcus and a region of the orbitofrontal cortex that is adjacent to olfactory association cortex.

摘要

我们对人类大脑中跨模态整合的神经关联的理解几乎完全来自于对听觉、视觉和躯体感觉的研究。戈特弗里德和多兰的一项新研究扩展了我们对多感官整合的理解，该研究表明视觉线索对气味检测的促进作用取决于物体的一致性，以及颞上沟和眶额皮质中与嗅觉联合皮质相邻区域活动的增强。
