Tóm tắt
We investigate in this paper the non-uniform sampling of EEG dipolar potentials and its impact on source analysis. We suppose some a priori knowledge on the approximate location of the dipole. We show that, in a noise-free situation, the electrode spacing needs to be around 3 cm in the region of the dipole only, whereas it can drop to 8 cm in remote regions.
