WebAround 90% of humans prefer their right hand for unimanual actions and are left- hemisphere dominant for language functions; a pattern far from negligible. The phenomena of handedness and cerebral lateralization for language are presented along with the different theories that attempt to explain the presence of these functional asymmetries. WebEvidence from both clinical and normal populations indicates that the organization of brain functions differs for right- and left-handers. In general, left-handers are less lateralized …
