Asymmetries in preparation for action.
The origins and nature of hemispheric specialization of action control are unclear. A review of some recent evidence suggests that the right hemisphere interprets spatial relationships whereas the left deals with temporal control of movement. Contrary to the popular view, specialization of the right hemisphere for spatial representations might have preceded left hemisphere specialization for language and movement.
