Diagram illustrating the statistical thresholding procedure. (A) The test statistic is calculated for every voxel for the original data,${\Psi }_r^O$. Then, for each resampling of the data, ${\Psi }_r^m$ is computed. Finally, the maximum over r is taken to obtain ${\Psi }^{ma{x}^m}$. (B) A histogram of the maximal distribution, ${\Psi }^{ma{x}^m}$, with arrows pointing to the 1st and 5th percentiles, corresponding to p < 0.01 and 0.05, respectively. (C) A histogram of the original statistic, ${\Psi }_r^O$, with the θ^max, p < 0.01 and θ^max, p < 0.05, corresponding to the values obtained in (B).
