摘要:  目的: 观察触觉刺激三叉神经上颌支(简称V2)面部支配区引起的大脑中枢反应区。 方法: 选取8名健康志愿者,用棉签刺激右侧面部三叉神经上颌支的支配区,采用触觉刺激减静息的组块设计方法,采集全脑血氧水平依赖对比的功能性MRI扫描数据。结果: 脑激活区为左侧初级躯体感觉皮质(BA3)、岛叶/SII、BA22、BA45,右侧BA40、BA9、BA38、BA41。结论: 对侧初级躯体感觉皮质、岛叶/SII和颞上回,同侧中央后回、颞下回和颞横回及双侧前额皮质是面部V2区触觉刺激激活的脑部功能区。

Abstract: Objective: To evaluate the brain cortical response to facial tactile in maxillary trigeminal division. Methods:8 healthy volunteers participated in the study. Cotton-tipped swab stimuli was applied to right side of face in maxillary trigeminal division, and block designed BOLD functional MRI scan covering the whole brain was carried out. Results:Increased BOLD signals during tactile stimulation were found in left SI (BA3), insula/SII, Brodman's area 22,45, and right Brodman's area 40,9,38,41. Conclusion:Tactile stimuli activated contralateral primary, secondary somatosensory cortex, superior temporal gyrus, ipsilateral postcentral gyrus , inferior temporal gyrus, transverse temporal gyrus, bilateral prefrontal cortex .
