| 目的探讨功能性磁共振显像作为一种无创伤性的方法在周围神经经低频电刺激对大脑影响中的应用。 方法用低频电刺激志愿者右腓总神经处，同时用功能性磁共振显像扫描头部。 结果所得资料均用SPM 99软件处理。双侧大脑半球的中央后回、颞上回和顶下小叶交汇处有一兴奋区域；双侧岛盖部(operculum)也有兴奋；另外，左侧大脑半球的中央后回顶上小叶、旁中央小叶和楔前叶交汇处有兴奋区；右侧大脑半球则在枕上回和顶上小叶之间有小片兴奋区域。 结论在周围神经经低频电刺激对大脑影响的研究中，我们发现功能性磁共振显像是一种有效的实用方法。 |

| Objective To evaluate the usefulness of functional magnetic resonance imaging (fMRI) as a noninvasive method in recording the activities of the human brain as excited by low frequency current(LFC) stimulator. MethodsThe right common peroneal nerves of 6 healthy volunteers were stimulated with LFC (NMR-II stimulator). The activities of the brain were then recorded and evaluated during the scanning by the fMRI technique. Data obtained during the study were dealt with with the software SPM99. Results In both cerebral hemispheres, the area where the postcentral and superior temporal gyrus, inferior parietal lobule met were excited, and so were the operculum at both sides. Postcentral gyrus, superior parietal and paracentral lobule, and the precuneus in the left cerebral hemisphere, as well as the superior occipital gyrus and the superior parietal lobule in the right hemisphere,were involved as the excited areas. Conclusion fMRI is a useful tool for recording and evaluating the brain activities excited by LFC. |
