SUMMARY

Six stroke patients were studied using a dichotic listening1 CV task, 4 with left hemisphere infarction, 2 with right hemisphere infarction. It was observed a «lesion--effect», a shift of hemisphere prevalence to the side opposite a brain lesion. The authors suggest that the lesion-effect can be explained by the auditory extinction phenomenon at the linguistic level.


RESUMO

Foram estudados 6 pacientes com infarto cerebral mono-hemisférico utilizando o teste de estimulação dicótica consoante-vogal (CV) para estudo da preferência hemisférica a estímulos verbais. Observou-se em todos os casos lateralização para o hemisfério não comprometido, sugerindo a participação do fenômeno de extinção auditiva ao nível lingüístico.
