Activation during the regulate negative > look negative condition was greater for those who denied use of sleep medication in the last 30 days (dark gray bars, n = 85) than for those who endorsed it (light gray bars, n = 12). Differences were significant in the medial prefrontal cluster (mPFC, p = .001) and left dorsolateral prefrontal cluster (dlPFC, p = .004) and there was a non-significant trend in the inferior parietal cortex cluster (IPC, p = .06).
