* Visual Cortex: This area processes the visual information of the signs.
* Motor Cortex: This area controls the movements of the hands and face used in signing.
* Broca's Area: This area is involved in language production, including the grammar and structure of sign language.
* Wernicke's Area: This area is responsible for language comprehension, including understanding the meaning of signs.
* Other Language Areas: The brain also uses other language areas, like the angular gyrus and the supramarginal gyrus, to process the complexities of sign language.
It's important to note that sign language is not just a visual language, it also involves auditory and kinesthetic (movement) aspects. This means different parts of the brain are activated simultaneously to understand and produce sign language.
Therefore, it's more accurate to say that sign language activates a network of brain areas, rather than just one specific part.
