Description:
After resection of the corpus callosum, V.J., a left-handed woman with left-hemisphere dominance for spoken language, demonstrated a dissociation between spoken and written language. In the key experiment, words flashed to V.J.'s dominant left hemisphere were easily spoken out loud, but could not be written. However, when the words were flashed to her right hemisphere, she could not speak them out loud, but could write them with her left hand. This marked dissociation supports the view that spoken and written language output can be controlled by independent hemispheres, even though before her hemispheric disconnection, they appeared as inseparable cognitive entities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baynes, K -- Eliassen, J C -- Lutsep, H L -- Gazzaniga, M S -- P01 NS 17778/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1998 May 8;280(5365):902-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience, University of California at Davis, Davis, CA 95616, USA. kbaynes@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9572734" target="_blank"〉PubMed〈/a〉
