Task and resting-state fMRI use the same acquisition parameters, with 2.4mm spatial resolution and TR=0.735s, with multiband acceleration factor of 8. A “single-band” reference image (without the multiband excitation, exciting each slice independently) is acquired that has higher tissue-type image contrast; this is used as the target for motion correction and alignment. For both data sets, the raw data are corrected for motion72 and distortion55 and high-pass filtered to remove temporal drift.
