Wernicke's area, located in the posterior superior temporal gyrus, is the primary brain region involved in language comprehension and processing.

Broca's area, located in the posterior inferior frontal gyrus, is primarily responsible for speech production and articulation.

The arcuate fasciculus is a white matter pathway that connects Broca's area and Wernicke's area, facilitating communication between these two language processing regions.

The angular gyrus, located at the junction of the parietal, temporal, and occipital lobes, is involved in semantic processing and the retrieval of word meaning.

The dorsolateral prefrontal cortex is involved in higher-order cognitive processes, including the processing of non-literal language and figurative speech.

Aphasia is a language disorder caused by brain damage that affects the ability to produce and understand language.

Broca's aphasia, also known as expressive aphasia, is a type of aphasia characterized by difficulty in producing speech, often with preserved comprehension.

Wernicke's aphasia, also known as receptive aphasia, is a type of aphasia characterized by difficulty in understanding language, often with preserved speech production.

Anomic aphasia is a type of aphasia characterized by difficulty in naming objects, often with preserved comprehension and speech production.

Conduction aphasia is a type of aphasia characterized by difficulty in repeating words or phrases, often with preserved comprehension and speech production.

fMRI (functional magnetic resonance imaging) is a neuroimaging technique that measures brain activity by detecting changes in blood flow, and is commonly used to study the neural basis of language.

Language activation refers to the increased activity in brain regions involved in language processing during language tasks.

In most individuals, the left hemisphere of the brain is dominant for language processing, including speech production and comprehension.

Language reorganization refers to the phenomenon where individuals with brain damage to the left hemisphere may show language processing in the right hemisphere, indicating the brain's capacity for neuroplasticity.

The hierarchical model of language processing proposes that language is processed in a hierarchical manner, with different levels of representation, from phonemes to words to sentences.
