Reliable inverse imaging of source currents in rat’s brain requires sufficiently accurate and CPU-time moderate forward models of fields to calibrate inverse solvers. In this paper, we compare different mathematical formulations of the electromagnetic problem related to the analysis of brain waves (static, quasi-static, full-wave) and various meshes differing in the density, the type and the geometrical accuracy. A sufficiently accurate model of brain waves is then completed by the cerebrospinal fluid and the skull. The resultant composite model of rat’s head with properly set electrical parameters has to be calibrated by the outputs of measurements. That way, a realistic electromagnetic model of the head of a live rat can be obtained. |
