Interhemispheric communication in a case of total visuo-verbal disconnection.

Interhemispheric communication strategies as noted in split-brain subjects may serve a compensatory function in patients with total visuo-verbal disconnection. The results of a case support this expectation. Identification of visual material reflected the perceptual and linguistic limitations of the right hemisphere, and naming was sometimes mediated by the rehearsal of alternatives. Implications for disconnection theory are discussed.
