Altered spontaneous activity in the default-mode network and cognitive decline in chronic subcortical stroke

The resting-state functional connectivity (rsFC) has been reported to be impaired in the default-mode network (DMN) in stroke patients. However, it remains unclear whether the regional homogeneity (ReHo) of spontaneous activity and gray matter volume (GMV) are also altered in the DMN in these patients. Here we investigated ReHo, rsFC and GMV changes in the DMN and their functional correlations in stroke patients.
