Language is a distinctly human symbol system that relates a

number of different types of forms to aspects of meaning. The forms of language and their associated meanings are activated in the processes of speaking, understanding speech, reading, and writing. Several types of data provide information about the way the brain is organized to represent and process language in these tasks. These include correlations between language processing deficits and brain lesions, regional cerebral blood flow and other hemodynamic responses to language processing in normal subjects, electro-

physiological and magnetoecephalographic responses to language processing in normal subjects, and the effects of electrocortical stimulation on language. These sources of data indicate that language is primarily represented and processed in perisylvian association cortex, with possible contributions from other brain areas. They indicate that different aspects of language processing are localized in different parts of the perisylvian cortex and lateralized differently in the two hemispheres. They also indicate that both localization and lateralization show some degree of variability across individuals.
