The subject remains difficult. The results are controversial and seem partly contradictory. Dissenting opinions abound. Further research is clearly needed to draw out the specific and nonspecific aspects of motor cortical function. With fMRI, positron emission tomography (PET), and other studies, however, we may now learn to appreciate the rules underlying cortical motor function and by these rules, understand how each specific study contributes to the results observed.
