Abstract

Handedness is often portrayed as a nonfunctional artifact of cerebral asymmetry. Our data, however, indicate that handedness reflects cerebral specialization for specific control processes. Each hemisphere/limb system is specialized for different but complementary functions: the dominant system for controlling limb trajectory dynamics, and the nondominant system for controlling limb position.
