Altered Function of Superior Parietal Lobule Associated with Perceptive Awareness in First-Episode Drug-Naïve Panic Disorders: A Preliminary fMRI Study.

The increased activation during interoceptive stimuli might render PD patients more engaged in processing information associated with their internal states.
