In the present study, we investigate the association between intrinsic reward network (β-network) and cognitive control network (δ-network) and anhedonia in depression patient. We found that depression patients showed decreased functional connectivity (FC) in intra- and inter- β- and δ-networks and the FC in both β- and δ-networks were significantly correlated with anhedonic severity in depression patients. Importantly, the integrated neural features of β- and δ-networks would more precisely predict anhedonia symptom. These findings indicated that the neural features in both β- and δ-networks would represent a fundamental mechanism underlying anhedonia in the MDD patients.
