Document Summary
We use language, art, and music in ways that are beyond the capacity of non-human species. The hemisphere that controls language is the dominant hemisphere. Language is found in the left cerebral hemisphere in a vast majority of people. Almost all right-handed people have left hemisphere dominance. More than half of left-handed people have left hemisphere dominance. The rest have right hemisphere dominance, or mixed dominance. Language transcends any particular sensory system not associated with a particular one. Visual input (reading and writing) occurs in the later stages of language acquisition. In children, language seems to develop faster in females. For people who are born deaf or who acquire deafness early in life, the sensory input for language development is visual. A large percentage of the cerebral cortex is involved in language/speech including . The areas that are directly involved cluster around the lateral fissure = perisylvian .
