Does reversed laterality really exist in dextrals? A case study.
We report a case of a right-handed patient who, after a massive left-hemisphere infarction, had neuropsychological disturbances compatible with a right-hemisphere lesion. This has been previously called 'reversed laterality'. Two new aspects of this pattern are described: the right hemisphere is as capable as the left in processing complex syntactic and higher psycholinguistic stimuli; reversed laterality is not complete, ideomotor praxis is the only function that does not follow an inverted representation. The existence of different forms of cerebral organization in dextrals is discussed.
