Noting that linguistics and the neurological sciences have developed independently, this paper presents a coordinated approach to man's understanding of language, cognition, and mind. A neurological model is developed following a discussion of the rationale of such an approach. Chapters include: (1) the relation of neurological evidence to models of language, (2) a schematic model of language, (3) functional anatomy of the central language system, (4) functional anatomy of the peripheral language modalities, and (5) concluding remarks. Tables and charts illustrate theory. Bibliographical references are included. (RL)
