Spatial sampling of MEG and EEG revisited: From spatial-frequency spectra to model-informed sampling
Joonas Iivanainen, Antti J. Mäkinen, Rasmus Zetter +3
In this paper, we analyze spatial sampling of electro- (EEG) magnetoencephalography (MEG), where the electric or magnetic field is typically sampled on a curved surface such as the…

Sampling theory for spatial field sensing: Application to electro- and magnetoencephalography
Joonas Iivanainen, Antti Mäkinen, Rasmus Zetter +3
We present a theoretical framework for analyzing spatial sampling of fields in three-dimensional space. The framework bridges Shannon's sampling and information theory to Bayesian…
