Emotion Study/Substudy: Flexible Brain Study

"Functional Magnetic Resonance Imaging Participants in the experimental group will be trained using functional magnetic resonance imaging to regulation brain activity in anterior cingulate cortex.~The anterior cingulate cortex is a brain region that is known to be involved in emotion processing. Activation of this region is expected to improve emotion processing."

"Functional Magnetic Resonance Imaging Participants in each group will be trained using functional magnetic resonance imaging to regulation brain activity in primary auditory cortex. The primary auditory cortex is a brain region that is NOT specifically involved in emotion processing. Activation of this region is NOT expected to improve emotion processing; and thus activation of this brain region serves as control/placebo condition in the current design (placebo comparator)."
