Abstract: Asymmetries  in  the  kinematics  and  neural  substrates  of  voluntary  right  and  left  eye-­hand coordinated   movements   have   been   accredited   to   differential   hemispheric specialization.  An  alternative  explanation  for  between-­hand  movement  differences  could result  from  hand-preference  related  effects.  To  test  both  assumptions,  an  experiment  was conducted   with   left-­   and   right-­handers   performing   goal-­directed   movements   with   either hand   paced   by   a   metronome.   Spatiotemporal   accuracy   was   comparable   between   hands, whereas   hand   peak   velocity   was   reached   earlier   when   moving   with   the   left   compared   to the  right  hand.  The  underlying  brain  activation  patterns  showed  that  both  left-­  and  right-­handers  activated  more  areas  involved  in  visuomotor  attention  and  saccadic  control  when using   their   left   compared   to   the   right   hand. Altogether, these results confirm a unique perceptuomotor processing specialization of the left brain/right hand system that is independent of hand preference.
