MRI Experiment Study on Neuronal Current Magnetic Field

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.
