EEG (electroencephalography) source localization is convenient methods to analyze brain activity because of non-invasiveness and high temporal resolution. However, large number of electrodes should be necessary for accurate source localization because the number of electrodes is insufficient to obtain high resolution potential map on the scalp.The goal of this study is to realize accurate source localization using small number of electrodes. When the region of the source is known in prior to measurement, it could be unnecessary that electrodes are evenly located the whole head. Electrode arrangements using electrodes near the target region are proposed. In addition, localization accuracies for proposed electrode arrangements are examined using sLORETA by the computer simulations. as the result, it was confirmed that source localization accuracies using proposed electrode arrangements were higher than that of standard electrode systems . |
