Comparison of FIRE (left, correlation threshold = 0.7) and SPM (right, uncorrected intensity threshold of P = 0.001) using a delayed boxcar reference vector. Neither motion correction nor spatial filters were applied. The subject simultaneously performed a visual activation (eyes open vs. eyes closed) and a standard motor task (finger tapping vs. rest). The activation patterns with both analysis methods are very similar. (EPI, TR: 3 sec, TE: 66 ms, matrix size: 32 × 32, voxel size: 6 × 6 × 6 mm3. Paradigm: 9 sec baseline, 9 sec activation, 21 sec baseline, 9 sec activation, 15 sec baseline).
