Abstract
We report the case of a 23 year old right-handed man, who suffered a calloso-occipital haemorrhage from a arterio-veinous malformation of the splenium of the corpus callosum. Six months after the haemorrhage, a MRI showed complete destruction of the posterior half of the corpus callosum and hypodense lesion in left precuneus. On tachistoscopical examination, the patient was unable or greatly impaired to read letters, words or geographical names or to name pictures or colours presented within left hemifield. Interhemispheric transfer of motion information was tested by presenting short sequences of coherent dot motion within left hemifield while the patient was fixating a central point. Eye movements were recorded with a camera and trials with saccades were rejected off-line. The patient reported accurately on coherent dot motion presented in the left hemifield.
