Abstract	Three objectives of research reported here were to describe the neural organization underlying language usage and language loss, to study activities occurring in both cerebral hemispheres, and to study neural changes related to changes in syntactic complexity of stimuli. A dichoptic procedure was chosen. A subject faced a viewing screen on which were flashed a fixation stimulus and two different short sentences, one on either side. The subjects were required to select a response picture appropriate to the sentences. Three subject groups were tested: (1) controls with no history of neurological damage; (2) a group of aphasic patients with unilateral left hemisphere brain damage; (3) a group with unilateral right hemisphere brain damage. The general conclusion was that the right hemisphere appears capable of processing some syntactically simple language stimuli; however, as stimuli become more complex, the left hemisphere may be necessary for comprehension. Testing involving cortical visually evoked responses recorded over both hemispheres simultaneously was conducted to see if visual AER's can be used to detect cortical language processing. It appears to be a useful means to study intra- and inter-hemispheric neural language systems. Charts and graphs illustrating research methods and findings are included. (CHK)
