The passive recipient: Neural correlates of negative self‐view in depression

Abstract

Abstract Introdction Previous studies have argued that people tend to isolate themselves from negative information. This tendency is modulated by the individual's role in social interaction, that is, as an initiative actor (e.g., “I hit Tom”) or a passive recipient (e.g., “Paul hits me”). Depressed patients tend to focus on negative aspects of themselves and cope with situations passively. It is still an open question how the actor/recipient role affects the behavioral and neural responses to self in depression. Methods The present study adopted functional magnetic resonance imaging (fMRI) technology to investigate behavioral and neural responses to self (as an actor/recipient) in depressed patients and the matched healthy controls when attributing negative events. Results Compared with healthy controls, depressed patients showed more self‐attribution for negative events. Depressed patients showed increased brain activity in the dorsal medial prefrontal cortex (dmPFC) subsystem of the default mode network (DMN) when they played recipient role in self‐related negative events. Activity of the dmPFC subsystem was negatively correlated with depressed patients’ self‐attribution for negative events in recipient condition. While decreased brain activity in the medial temporal lobe (MTL) subsystem was observed in depressed patients when they played the actor or recipient role in self‐related negative events. Activity of the MTL subsystem was negatively correlated with depressed patients’ reaction time when they played recipient role in selfrelated negative events. Conclusion These results implicated that depressed patients manifested the negative self‐view. Actor/recipient role affected their activation patterns in the DMN which were different from the healthy controls. The correlation between the abnormal brain activations of the DMN and the behavioral performances might manifest more easily when depressed patients played recipient role in negative events.
