Fig. 1

I The decomposed dictionary components from the fMRI data during one single task and II the 14 corresponding reference weight maps by applying the HAFNI method to the whole-brain fMRI signals. This figure visualizes 14 selected dictionary components which are either motor task-evoked networks (M1–M5) or resting state networks (RSN1–RSN9). The green bars in (I) show 400 dictionary network components (indexed along x-axis) and the spatial non-zero voxel numbers that each component’s reference weight map contains (represented by the horizontal height of each bar). The panels in (II) visualize the temporal time series (white curve) and spatial distribution map (eight representative volume images) of each network. The red curves represent the task contrast designs of the motor tfMRI data. (Color figure online)
