[Deficitis in the "verbal fluency" test in left-handed subject with unilateral hemispheric lesions]

In contrast to findings in right-handed subjects with a unilateral hemispheric lesion, in the left-handed there is no significant difference in "verbal fluency) test scores between right and left lesions, nor between anterior and posterior lesions. These findings are in favour of a certain degree of cerebral ambilaterality and of a lesser focalisation of the mechanisms responsible for language in the left-handed than in the right right-handed.
