Neural substrates of trait ruminations in depression.

ABSTRACT: Rumination in depression is a risk factor for longer, more intense, and harder-to-treat depressions. But there appear to be multiple types of depressive rumination-whether they all share these vulnerability mechanisms, and thus would benefit from the same types of clinical attention is unclear. In the current study, we examined neural correlates of empirically derived dimensions of trait rumination in 35 depressed participants. These individuals and 29 never-depressed controls completed 17 self-report measures of rumination and an alternating emotion-processing/executive-control task during functional MRI (fMRI) assessment. We examined associations of regions of interest--the amygdala and other cortical regions subserving a potential role in deficient cognitive control and elaborative emot
