Related to cerebral dominance: dominant hemisphere

ce·re·bral dom·i·nance

the fact that one hemisphere is dominant over the other and will thereby exercise greater influence over certain functions; the left cerebral hemisphere is usually dominant in the control of speech, language and analytic processing, and mathematics, whereas the right hemisphere (usually nondominant) processes spatial concepts and language as related to certain types of visual images; handedness (right-handed people have left cerebral dominance) is considered a general example of cerebral dominance.

(ser'ĕ-brăl dom'i-năns)
The fact that one hemisphere is dominant over the other and exercises greater influence over certain functions; the left cerebral hemisphere is usually dominant in the controlof speech, language and analytic processing, and mathematics, whereas the right hemisphere (usually nondominant) processes spatial concepts and language as related to certain types of visual images; handedness (right-handed people have left cerebral dominance) is considered a general example of cerebral dominance.

cerebral dominance

The control of speech and handedness by one hemisphere of the brain. In 90% to 95% of human beings, the left cerebral hemisphere is functionally dominant; as a result most people are right-handed. A lesion (such as a stroke or tumor) to the left cerebral hemisphere of such people will produce aphasia and right-sided paralysis. Aphasia rarely occurs in right-handed people from a right cerebral lesion. In 60% of left-handed people with aphasia from a cerebral lesion, the left side is affected. In some left-handed patients, it is possible that language function is controlled partially by both the left and right cerebal hemispheres.

To determine if there is an association between sidedness of cell phone use and auditory or language hemispheric dominance, the Henry Ford team developed a online survey using modifications of the Edinburgh Handedness protocol, a tool used for more than 40 years to assess handedness and predict cerebral dominance.

Among individuals carrying the 'right shift' (rs+) allele, the distribution is shifted in favour of right-handedness and left-cerebral dominance for speech, more so in homozygotes (rs++genotype) than in heterozygotes (rs+ -genotype), while the distribution of those without the rs+allele (rs- - genotype) shows no overall biases in handedness or cerebral dominance. In a similar theory proposed by McManus (1985), the focus is on hand preference rather than skill.
