Figure 2.

Group-averaged motor network (MN) connectivity maps generated with different physiological correction strategies, using long-TR, short-TR, and down-sampled short-TR data. A motor network template from the atlas generated by Yeo et al. (2011) is shown at the bottom for reference. CRV correction alters connectivity maps more than correction for PETCO₂ (labeled as CO₂) and RVT by reducing the extent of connected clusters outside the motor cortex. Sampling-rate does not seem to have a considerable effect on the connectivity maps.
