Fig. 1From: Increased activation of the pregenual anterior cingulate cortex to citalopram challenge in migraine: an fMRI studyBOLD signal changes over time after citalopram minus placebo data extraction in three clusters of the ACC with error bars (standard error of mean), for control and patient groups, respectively. Coronal and sagittal view of ROI analysis results were made by p(FWE) < 0.05 secondary threshold (with p < 0.001 primary threshold, k ≥ 5, CO = control group, M = migraine group)Back to article page
