Figure 2. Functional images obtained from a research volunteer asked to perform a verbal recognition task.

Views are from left (A), right (B), and superior (C) aspects. Different methods of multivariate correction are used, with the results superimposed. In red, activations are set at an uncorrected p level of 0.001. Blue demonstrates the overlap of activations with an false discovery rate (FDR) threshold of 3, with a cluster level of 47 (representing a corrected FDR level). In green are activations at a familywise error of 0.05, with a cluster of 0. Note how sensitivity and specificity differ between these methods.
