The desired vs. actual (permutation) false positive rates, collapsing results from all feature numbers (1, 2, 5, 10, 20, and 50) and grid spacing for tests on evoked (blue circles) and induced (red squares) responses for whole brain (A), occipital (B) and Heschl's gyrus (C) ROIs. The error bars show the standard deviation. Note that the tests of power seem to be less conservative than those of evoked responses. The purple triangles are the false positive rates when applying the same heuristic to the mass-multivariate minimum norm scheme (Soto et al., 2009) reconstructed on the canonical mesh.
