Note also this paper worth reading around this topic of motion correction:
L. Freire <http://brainvisa.info/biblio/en/Author/FREIRE-L.html> and
J.-F. Mangin <http://brainvisa.info/biblio/en/Author/MANGIN-JF.html>.
*Motion correction algorithms may create spurious brain activations in
the absence of subject motion*. /Neuroimage/, 14(3):709--722, 2001
