Stimulation state affected prefrontal oxygenated hemoglobin concentration during emotional stimuli. Areas of color indicate regions of significant change; warm colors indicate significant increase while cool colors indicate significant decrease in prefrontal oxyHb. Arrows indicate the direction of change. A During neutral stimuli there were no significant changes in prefrontal activity in the DBSon compared to the DBSoff state. B, C Images represent the difference in prefrontal activation between DBSon compared to DBSoff during emotional relative to neutral videos. B During positive valence stimuli DBS patients had significantly less frontal polar oxygenated hemoglobin concentration in the DBSon state than the DBSoff state. C During negative stimuli the DBSon state was correlated with decreased frontopolar and right lateral prefrontal cortex oxyHb concentration and increased bilateral inferior ventrolateral prefrontal cortex oxyHb concentration compared to DBSoff
