ABSTRACT
The present paper reports the results of a fMRI subtraction study of the pattern of cortical activation induced by an ideational praxis paradigm in six normal right-handed subjects. The control task consisted of a sequence of complex meaningless hand movements. A complete study was done for each hand in each subject. The left intraparietal sulcus was the only structure activated in all subjects regardless of the hand used in the task. These findings, albeit preliminary, suggest that the organization of actions involving the mediation of tools and utensils are strongly lateralized to the left hemisphere and that damage to the dominant imtraparietal sulcus may be critical for the development of the clinical syndrome of conceptual apraxia.
