His work on hemispheric specialization culminated in the "novelty-routinization" theory positing that (for the predominantly right-handed population) the two cerebral hemispheres are differentially involved in processing novel, unknown information (the right hemisphere) and processing in terms of stable pattern-recognition devices for known situations of mental routine (the left hemisphere).
[30]: 107 [31] Interestingly, research has shown quite opposite function of brain lateralisation, i.e. right hemisphere creatively and chaotically links between concepts and left hemisphere tends to adhere to specific date and time, although generally adhering to the pattern of left-brain as linguistic interpretation and right brain as spatio ...
In consequence, today the discovery of the link between the left hemisphere and speech is typically credited to Paul Broca. According to authors Cubelli and Montagna, the Broca's theory should be renamed: "Probably, Broca was aware of the paper prior to 1865, but he never acknowledged Dax's original theoretical contribution.
The left hemisphere is associated with language and calculations, while the right hemisphere is more closely associated with visual-spatial recognition and facial recognition. This lateralization of brain function results in some specialized regions being only present in a certain hemisphere or being dominant in one hemisphere versus the other.
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 ...
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 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".

Neuroscience of multilingualism is the study of multilingualism within the field of neurology.These studies include the representation of different language systems in the brain, the effects of multilingualism on the brain's structural plasticity, aphasia in multilingual individuals, and bimodal bilinguals (people who can speak at least one sign language and at least one oral language).
