Abstract

We investigated the influence of electrode contact size on cortical electroencephalogram (EEG) sensitivity distributions. We focused this investigation on the fifth sensitivity volume (FSV) of mapping the lead field in the cortex. We evaluated the cortical sensitivity in concentric spheres and realistic models, using electrode diameters of 1 mm, 5 mm, 10 mm, and 15 mm. We found that when electrodes were spaced farther apart than the bipolar pair of the 128-channel montage, real dimensional electrodes should be used rather than point electrodes in the simulation studies.
