Abstract:
To address the influence of language presentation on cerebellar activation, hearing volunteers were compared with deaf individuals using functional magnetic resonance imaging during observation of German sign language and text reading. In deaf participants, German sign language revealed activation of the auditory and language-related areas including the medial temporal gyrus (BA 21) and Crus I. In normal hearing participants not understanding German sign language, Crus I was less activated during observation of German sign language but strongly activated during text reading and accompanied by activation of the medial temporal gyrus. Our results indicate that cerebellar activation in Crus I corresponds to language perception as correlated with cortical activation in language-related areas and is not dependent on the mode of language presentation.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
