Using enhanced FDR to find activation in FMRI images

Abstract

The False Discovery Rate (FDR) criterion has been proposed for use in multiple-comparisons testing problems (Benjamini and Hochberg, 1995). A multiple testing procedure uses the FDR criterion if the procedure controls the expected proportion of false positives that are identified as active. Functional Magnetic Resonance Imaging (FMRI) are used to create images of a subject\u27s brain which show changes in blood oxygenation that can occur because of regional brain activation. The aim of many FMRI experiments is to locate regions of the brain that are activated by a specific task
