The angular gyrus is a region of the brain that is involved in a variety of language functions, including processing and producing sign language. It is located in the posterior parietal lobe and is connected to other brain regions involved in language, such as Broca's area and Wernicke's area.

Sign language is processed in both the same and different brain regions than spoken language. Some brain regions, such as the angular gyrus, are involved in processing both sign language and spoken language. However, other brain regions, such as the hand motor cortex, are involved in processing sign language but not spoken language.

The neural mechanisms underlying sign language acquisition and development are both the same and different from those underlying spoken language acquisition and development. Some neural mechanisms, such as the development of brain regions involved in language processing, are the same for both sign language and spoken language. However, other neural mechanisms, such as the development of hand motor skills, are different for sign language and spoken language.

The hand motor cortex is a region of the brain that is involved in controlling hand movements. It is located in the precentral gyrus of the frontal lobe and is connected to other brain regions involved in language, such as Broca's area and Wernicke's area. The hand motor cortex is necessary for the production of sign language, as it allows signers to make the precise hand movements that are required to communicate.

The brain represents the meaning of sign language words in both the same and different ways than it represents the meaning of spoken language words. Some aspects of the brain's representation of meaning are the same for both sign language and spoken language, such as the activation of semantic networks. However, other aspects of the brain's representation of meaning are different for sign language and spoken language, such as the involvement of visual-spatial processing in sign language.

The cerebellum is involved in the coordination of hand movements during sign language production. It receives input from the motor cortex and other brain regions involved in language processing, and it helps to coordinate the precise hand movements that are required to produce sign language.

Broca's area is involved in the processing of sign language grammar. It is located in the left frontal lobe and is connected to other brain regions involved in language processing, such as Wernicke's area and the angular gyrus. Broca's area is responsible for the production of grammatical sentences in sign language.

The brain processes sign language in bilingual individuals in both the same and different ways than it processes sign language in monolingual individuals. Some aspects of the brain's processing of sign language are the same in bilingual and monolingual individuals, such as the activation of the angular gyrus. However, other aspects of the brain's processing of sign language are different in bilingual and monolingual individuals, such as the involvement of the hand motor cortex in bilingual individuals.

Neural correlates of sign language fluency include increased activation in Broca's area, Wernicke's area, the angular gyrus, the hand motor cortex, the cerebellum, and the basal ganglia. These brain regions are all involved in different aspects of sign language processing, and their increased activation in fluent signers suggests that they play a role in the development of sign language fluency.

The brain processes sign language in deaf individuals who have never been exposed to spoken language in both the same and different ways than it processes sign language in deaf individuals who have been exposed to spoken language. Some aspects of the brain's processing of sign language are the same in deaf individuals who have never been exposed to spoken language and deaf individuals who have been exposed to spoken language, such as the activation of the angular gyrus. However, other aspects of the brain's processing of sign language are different in deaf individuals who have never been exposed to spoken language and deaf individuals who have been exposed to spoken language, such as the involvement of the hand motor cortex in deaf individuals who have never been exposed to spoken language.

Neural correlates of sign language comprehension include increased activation in Broca's area, Wernicke's area, the angular gyrus, the hand motor cortex, the cerebellum, and the basal ganglia. These brain regions are all involved in different aspects of sign language processing, and their increased activation in comprehending signers suggests that they play a role in the development of sign language comprehension.

The brain processes sign language in hearing individuals who have learned sign language as a second language in both the same and different ways than it processes sign language in deaf individuals. Some aspects of the brain's processing of sign language are the same in hearing individuals who have learned sign language as a second language and deaf individuals, such as the activation of the angular gyrus. However, other aspects of the brain's processing of sign language are different in hearing individuals who have learned sign language as a second language and deaf individuals, such as the involvement of the hand motor cortex in hearing individuals who have learned sign language as a second language.

Neural correlates of sign language production include increased activation in Broca's area, Wernicke's area, the angular gyrus, the hand motor cortex, the cerebellum, and the basal ganglia. These brain regions are all involved in different aspects of sign language processing, and their increased activation in producing signers suggests that they play a role in the development of sign language production.

The brain processes sign language in individuals who have aphasia in both the same and different ways than it processes sign language in individuals who do not have aphasia. Some aspects of the brain's processing of sign language are the same in individuals who have aphasia and individuals who do not have aphasia, such as the activation of the angular gyrus. However, other aspects of the brain's processing of sign language are different in individuals who have aphasia and individuals who do not have aphasia, such as the involvement of Broca's area and Wernicke's area in individuals who have aphasia.
