Current opinion in neurobiology, 1996•ElsevierStudies in brain-damaged patients indicate that the left hemisphere in right-handers is
specialized for controlling cognitive-motor tasks in both arms. Recent functional imaging
data support this conclusion, with the finding that ipsilateral, as well as contralateral,
movements activate the left, but not the right, motor cortex or associated areas of either
hemisphere. Future studies must aspire to identify the mechanisms for this asymmetry.
