Effect on the Brain Surface Potentials due to the Hematoma within Brain and Conductivity of Skull in a 3-D Sphere Model

摘要

Based on the disturbance method of electrical current fields, the numerical computation about the effect on the brain surface potentials (BSPs) of the change of hematoma within brains in a 3-D sphere model is described in this paper. The results show that the change of BSPs is very obvious and regular when the volume or position of the hematoma in a brain changes. These results are very valuable to estimate the change of the hematoma in a brain. In this paper the effect of the conductivity of the skull on the BSPs is described as well.
