Figure 6.

Sensitivity maps of the cerebellum and the cerebral cortex for MEG magnetometers (a), MEG gradiometers (b), and EEG (c). The color of the source corresponds to the Euclidean norm of the signal in sensor space resulting from a dipole of strength 100 nAm activated at that source point. The color scale was chosen to range from the first percentile to the 99th percentile of all cerebellar signal norms. Source points that were excluded due to the 5 mm distance limit to the inner skull boundary are black. Plane 1 is the midsagittal section of the cerebellum (vermis) and Plane 2 makes a 45° angle with the midsagittal plane in the lateral direction
