Do mood-linked responses in medial prefrontal cortex predict relapse in patients with recurrent unipolar depression?
Medial prefrontal cortical reactivity to mood provocation in remitted unipolar depressed patients serves as a marker of relapse risk rather than successful emotion regulation. Enduring remission is characterized by normalization of the mPFC to that of healthy control subjects. Furthermore, visual cortex reactivity predicts resilience against depressive relapse, indicating a prophylactic role for sensory rather than ruminative cognitive reactivity in the processing of negative emotion.
