采用高度异质有限元模型研究了一名成年男性受试者的软颅骨、脑脊液和灰质对头皮电位的影响。这些模型是由分割的T1加权磁共振图像构建的。模型体素分辨率为1x1x3.2 mm，共计约150万体素。由于运动皮质区域的偶极源，头皮电位用自适应有限元求解器计算。结果发现，模型的头皮电位受软骨、脑脊液和灰质组织边界的显著影响。
Effects of soft skull bone, cerebrospinal fluid (CSF) and gray matter on scalp potentials were examined with highly heterogeneous finite element models of an adult male subject. These models were constructed from segmented T1 weighted magnetic resonance images. Models had voxel resolutions of 1x1x3.2 mm with a total of about 1.5 million voxels. The scalp potentials, due to a dipolar source in the motor cortex area, were computed with an adaptive finite element solver. It was found that the scalp potentials were significantly affected by the soft bone, CSF and gray matter tissue boundaries in the models.
