UM, University of Michigan. Movement deviations are the standard deviations of the realignment adjustments over the 8-min resting state scan.

^aLevene's test significant at p < 0.05.

^bReliability of movement ICC for all subjects was 0.38, 0.66, and 0.56^c for pitch, roll, and yaw, respectively.

^cNot significantly different from zero at p < 0.05.
