Head-Specific Spatial Spectra of Electroencephalography Explained: A Sphara and BEM Investigation
Recent Publication
A research team led by Dr Uwe Graichen and Prof. Dr Sascha Klee from the Department of Biostatistics and Data Science, together with researchers from Ilmenau, has developed new models to make the measurement of brain waves using EEG more accurate. Instead of simplified spherical models, they used realistic 3D head models, which show that conventional electrode arrangements sometimes significantly misjudge the EEG signals. The study shows that with the usual 10-20 arrangement, the measurement results can deviate by up to 50%; even with 64 electrodes, the deviation is still up to 15%. These findings are important for more precise diagnoses and for therapies such as electrical brain stimulation, which require better spatial recording.
