A NIRS-fMRI study of resting state network

► Resting state NIRS signals mainly reflect spontaneous hemodynamic fluctuations. ► Concurrently obtained NIRS signals corresponded with fMRI signals of close regions. ► NIRS signals reproduced resting state networks including the default mode network. ► The results suggest that NIRS can be used to characterize resting state networks. ► The results promote to study functional connectivity with NIRS in diverse situations.
