In neuroscience and psychology, the term language center refers collectively to the areas of the brain which serve a particular function for speech processing and production. [1] Language is a core system that gives humans the capacity to solve difficult problems and provides them with a unique type of social interaction . [ 2 ]
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]
Some people may use the right hemisphere for language, and isolated damage of Wernicke's area cortex (sparing white matter and other areas) may not cause severe receptive aphasia. [5] [23] Even when patients with Wernicke's area lesions have comprehension deficits, these are usually not restricted to language processing alone.
Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production.
The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. [3] The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memory, language comprehension, and emotion association. [4]: 21 Temporal refers to the head's temples.
The left cerebral hemisphere of the brain.. The left-brain interpreter is a neuropsychological concept developed by the psychologist Michael S. Gazzaniga and the neuroscientist Joseph E. LeDoux.
More functions associated with language in Brodmann area 22 include producing sentences, semantic processing, and processing of complex sounds. [3] This area of the human brain supports lexical semantic processing and is responsible for language comprehension and production. Wernicke's area is shown to support lexical-semantics because lesions ...
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).
