| Research Abstract |
We conducted neuroimaging studies to investigate specific patterns of cognitive-emotional interaction and the underlying neurocircuitry in healthy controls and stress-related psychiatric disorders like depression and eating-disorders. The findings of our studies using various cognitive-emotional tasks and functional magnetic resonance imaging suggest that prefrontal and anterior cingulate cortex cognitively modulate emotional responses mediated by amygdala, and functional changes of these regions are present in stress-related psychiatric disorders.
