| 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. |
