Abstract:
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. Methods The 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.
