      abstract     = {Previous studies showed that imitation of finger and
                      hand/arm gestures could be differentially impaired after
                      brain damage. However, so far, the interaction between
                      gesture meaning and body part in imitation deficits has not
                      been fully assessed. In the present study, we aimed at
                      filling this gap by testing 36 unilateral left brain-damaged
                      patients with and without apraxia (20 apraxics), and 29
                      healthy controls on an imitation task of either finger or
                      hand/arm meaningful (MF) gestures and meaningless (ML)
                      movements, using a large sample of stimuli and controlling
                      for the composition of the experimental list. Left-brain
                      damaged patients imitated ML finger worse than hand/arm
                      movements, whereas they did not show the same difference in
                      MF gesture imitation. In addition, apraxic patients imitated
                      finger movements worse than hand/arm movements. Furthermore,
                      apraxic patients' imitation performance was equally affected
                      irrespective of the action meaning, whereas non-apraxic
                      patients showed better imitation performance on MF gestures.
                      Results suggest that MF gestures are processed as a whole,
                      as imitation of these gestures relies on the stored motor
                      programs in long-term memory, independently of the body part
                      involved. In contrast, ML movements seem to be processed
                      through direct visuo-motor transformations, with left-brain
                      damage specifically disrupting imitation performance of the
                      more cognitive demanding finger movements.},
