Language functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right-handed individuals. [7] While language production is left-lateralized in up to 90% of right-handers, it is more bilateral, or even right-lateralized, in approximately 50% of left-handers. [8]
In other studies, dyslexia is correlated with anatomical differences in the corpus callosum, the bundle of nerve fibers that connects the left and right hemispheres. [ 58 ] Data via diffusion tensor MRI indicate changes in connectivity or in gray matter density in areas related to reading and language.
The left hemisphere is usually dominant in right-handed people, although bilateral activations are not uncommon in syntactic processing. It is now accepted that the right hemisphere plays an important role in the processing of suprasegmental acoustic features like prosody , which is "the rhythmic and melodic variations in speech".

In both types of languages, they are affected by damage to the left hemisphere of the brain rather than the right -usually dealing with the arts. There are obvious patterns for utilizing and processing language. In sign language, Broca’s area is activated while processing sign language employs Wernicke’s area similar to that of spoken language.
Prior to the research done on Genie, it was hypothesized that the critical period to acquire a first language would end when the brain lateralized, meaning the tendency for certain functions of the brain to be localized to one hemisphere as opposed to the other. [15] Language is typically localized to the left hemisphere.
The language module or language faculty is a hypothetical structure in the human brain which is thought to contain innate capacities for language, originally posited by Noam Chomsky. There is ongoing research into brain modularity in the fields of cognitive science and neuroscience , although the current idea is much weaker than what was ...
It is based on evidence that shows that the left and right hemispheres differentially contribute to language comprehension. [17] Generally, the neural structures that support language production are predominantly in the left hemisphere for most individuals creating a hemispheric asymmetry , which results in differential language processing ...
The reasons for this are not fully understood, but it is thought that because the left cerebral hemisphere of the brain controls the right side of the body, the right side is generally stronger; it is suggested that the left cerebral hemisphere is dominant over the right in most humans because in 90–92% of all humans, the left hemisphere is ...
