本研究采用回波平面功能磁共振成像（fMRI）研究了参与识别口语中表达的单词的情感韵律和音素成分的神经区域。10名右撇子男性被要求根据tither表达的情绪语调（愤怒，快乐，悲伤，或中性）或音素特征，特别是，初始辅音的声音（bower，dower，power，或tower）来区分单词。与基线活动相比，在检测语言的情感和口头方面时观察到显著的双边活动。我们发现，与言语检测相比，情绪检测导致右下额叶的显著活动。相反，言语刺激的检测与情绪的检测相比，激活左下额叶区域最为显著。对前听觉皮层的具体分析显示，与言语检测期间的活动相比，情感检测期间的右半球活动增加。这些研究结果说明双边参与语言中的情感检测，同时伴随着显着偏侧活动的情绪和言语检测，在颞叶和额叶。(C)2000 Elsevier Science B.V.保留所有权利。
This study examined the neural areas involved in the recognition of both emotional prosody and phonemic components of words expressed in spoken language using echo-planar, functional magnetic resonance imaging (fMRI). Ten right-handed males were asked to discriminate words based on tither expressed emotional tone (angry, happy, sad, or neutral) or phonemic characteristics, specifically, initial consonant sound (bower, dower, power, or tower). Significant bilateral activity was observed in the detection of both emotional and verbal aspects of language when compared to baseline activity. We found that the detection of emotion compared with verbal detection resulted in significant activity in the right inferior frontal lobe. Conversely, the detection of verbal stimuli compared with the detection of emotion activated left inferior frontal lobe regions most significantly. Specific analysis of the anterior auditory cortex revealed increased right hemisphere activity during the detection of emotion compared to activity during verbal detection. These findings illustrate bilateral involvement in the detection of emotion in language while concomitantly showing significantly lateralized activity in both emotional and verbal detection, in both the temporal and frontal lobes.
