Abstract

Activations in the temporal lobes previously observed using positron emission tomography and auditory stimuli were partially reproduced with functional MRI and echo-planar imaging at 1.5 T in six volunteers performing tone and phoneme monitoring tasks. Verbal processing compared to a tone recognition task significantly activated a cortical area located in the left anterior temporal region (P < 0.02).

摘要

在六名执行音调与音素监测任务的志愿者中，使用正电子发射断层扫描和听觉刺激先前观察到的颞叶激活，在1.5T的功能磁共振成像和回波平面成像中部分得到重现。与音调识别任务相比，言语处理显著激活了位于左前颞区的一个皮质区域（P < 0.02）。
