中文摘要：

利用人类脑电alpha波在睁眼时被阻断的现象,设计了用磁共振检测脑电信号中最高能量段的alpha波的实验。结果表明,所得磁共振信号alpha频段在不同条件下有明显的改变,且主要在alpha活动明显的枕区有比较一致的变化,从而初步证明,在特定的条件下,应用磁共振检测神经电流活动信号是可能的。

英文摘要：

Neuronal current magnetic resonance imaging（nc-MRI） can improve the temporal resolution of functional magnetic resonance imaging（fMRI）.To explore the feasibility of the nc-MRI,an experiment is designed by,using MR to detect the differences of alpha wave activity under different conditions.One of the conditions is in the darkness with eyes closed to promote alpha wave activity and the other is a visual stimulus with eyes opened to suppress alpha wave activity.Our results show that the MR signal obtained in the alpha band changes significantly,and the changes in the occipital area where the alpha activity is prominent are more consistent.that means,in particular conditions,it is possible to apply nc-MRI to detect neuronal current activity.
