Broca's area, located in the left frontal lobe, is the primary brain region involved in language production, including speech articulation and grammar.

Wernicke's area, situated in the left temporal lobe, is primarily responsible for language comprehension, including understanding spoken and written language.

Broca's aphasia primarily affects language production, resulting in difficulty speaking and speech apraxia (difficulty coordinating the muscles involved in speech). Impaired comprehension is typically associated with Wernicke's aphasia.

The angular gyrus, located at the junction of the parietal and temporal lobes, is involved in semantic processing, including understanding the meaning of words and sentences.

The frontal lobe, particularly the prefrontal cortex, is the primary brain region involved in working memory, which is essential for language comprehension and production.

Aphasia is a language disorder that affects the ability to produce and/or comprehend language, often resulting from damage to the brain's language areas.

Wernicke's aphasia is characterized by fluent but often incomprehensible speech due to impaired language comprehension and difficulty finding the right words.

Agnosia, specifically auditory agnosia, refers to the inability to understand spoken language, often resulting from damage to the brain's language processing areas.

The angular gyrus, located at the junction of the parietal and temporal lobes, is involved in the processing of syntax, including the understanding and production of grammatical structures.

Dyslexia is a specific learning disability that affects the ability to read, often resulting from difficulties with phonological processing and decoding written words.

The prefrontal cortex, particularly the ventromedial prefrontal cortex, is involved in the processing of pragmatics, including understanding and producing language in a socially appropriate manner.

Dysgraphia is a specific learning disability that affects the ability to write, often resulting from difficulties with motor control, spatial awareness, and language processing.

The superior temporal gyrus, particularly the posterior superior temporal gyrus, is involved in the processing of phonology, including the perception and production of speech sounds.

Dysarthria is a speech disorder that affects the ability to speak, often resulting from damage to the brain's motor areas, nerves, or muscles involved in speech production.

The inferior frontal gyrus, particularly the pars triangularis and pars opercularis, is involved in the processing of semantics, including the understanding and production of word and sentence meaning.
