(A) Areas involved more in gesture planning in left-handers: Areas engaged more by left-handers were located either in the right hemisphere, i.e. right ANg, dPMC, or bilaterally (dorso-medial, and dorso-lateral prefrontal cortices). (B) Areas involved more in gesture production in left-handers: Again, except for the left-sided early visual and cerebellar contribution, areas engaged more by left-handers were in the dorso-medial prefrontal cortices. (C) Areas involved more in gesture production in right-handers: In addition to left SPL, dPMC, MFg, and some dPMC, and SMg/aIPS, there was also some noticeable involvement of the left anterior STg, and the nearby insular cortex. The right-hemisphere involvement was substantially less pronounced and included some lateral-ventral prefrontal contributions.
