Abstract:
The right and left hemispheres of the brain play somewhat different roles but help each other perform higher cortical functions. A 43 year-old right-handed woman was admitted due to a intraventricular hemorrhage followed by hydro-cephalus. A brain MRI revealed an intraventricular hemorrhage in the lateral, 3rd, and 4th ventricle and the hemorrhage in the lateral ventricle was compressing the genu of the corpus callosum. When asked to draw the face of a clock, she placed the numbers in reverse order (counter clockwise) when performing the task with her right hand, whereas the same task performed by the left hand was normal. In addition, when she wrote out simultaneously with right and left hands , she wrote Korean words in their mirror image with her left hand . When she wrote Chinese characters, she performed better with her right hand. These findings revealed some aspects of interhemispheric interaction in processing the images of a clock, and the orthographic lexicon of Korean and Chinese characters.
