Pure motor hemiparesis and thalamic hemorrhage.

and Orgogozo and Larsen4 provide powerful evidence that the supplementary motor areas modulate the motor programming of repetitive and sequential movements, including articulation, rather than attention. Since the supplementary sensory areas seem to have sensory functions analogous to the motor functions of the supplementary motor areas,’ I suspect the supplementary sensory areas have something to do with the actual processing of sensory information, including the comprehension of spoken language, that goes far beyond attentional mechanisms. What this processing entails, however, remains to be discovered.
