Abstract:
ObjectiveTo study the effect and clinical meaning and pathogenic of extinction on cerebral cortex lesion. MethodsTactile extinction to classical extinction test(simple stimuli)and modified Quality extinction test(QET)were used. ResultsThe positive rate of ex-tinction using modified QET was higher than that of simple stimuli; left cortex lesion could result in extinction both in the contralateral side andthe ipsilateral side;left frontal sites lesion caused ipsilateral extinction. Conclusion: The modified QET was more sensitive than simplestimuli; modified QET showed extinction has competiting and restricting effect at 2 different levels, the mechanism of extinction is correlatedto competition and adventage restraint of diplo-hand cerebral hemisphere and liaise correliation fiber of diplo-hand cerebral hemisphere; thehighesttthe positive rate of extinction was observed in left parietal lesions.
