“…For animal brain mapping we used two types of spline interpolation: spherical splines and 3D splines. Both of these methods are used in human brain mapping but not applied in rats yet [16][17][18][19][20].…”

“…However the rats brain can not be approximated well by a simple sphere. Based on results in the studies [18], [19] we can say, that we get better results when we use 3D splines for brain mapping in humans. In this paper, the 3D splines are applied in rats for the first time.…”

“…In this paper, the 3D splines are applied in rats for the first time. Efficiency of interpolation methods is computed by using Root Mean Squared error (RMS) between measured and interpolated signals under the electrodes [18], [19]. First step in brain mapping with spherical splines and 3D splines is the projection on the sphere [18][19][20].…”

Measurements of brain electrical activity in animals are essential for the validation of the pharmaco-effect of drugs. The way to evaluate these recordings should be comparable to that of EEG in humans. Methods that visualize the results of the measured EEG recording include brain mapping in two-dimensional or three-dimensional space. The most commonly used methods of interpolation techniques in humans are spherical splines and 3D splines. We measured nine brains of Wistar rats and compared them with a brain model from the atlas (Brain Atlas Reconstructor, BAR). We validated the brain model of Wistar rat for future use. We implemented a module in MATLAB 2015a for brain mapping, specifically, we implemented algorithms for spherical and 3D spline mapping. The root mean square error of the spherical spline method is 0.5943 in the case of testing signal and 0.6291/0.6388 in the case of real data estimation. The root mean square error of the 3D spline method is 0.4334 in the case of testing signal and 0.0849/0.0768 in the case of real data estimation. Our results show that the 3D spline method with the projection on sphere gives significantly better 3D potential map than spherical splines.
