Abstract

Aims - This review is a summary of four studies investigating the effect of epileptic disturbance and other functional factors on the brain lateralization. Methods - Patients were investigated by functional MRI by using visual, sensorimotor, memory, and speech paradigms. Results - 1. Malformations of cortical development localized within speech centers induce contralateral speech reorganization in only 50% of cases. 2. Epileptic disturbance can induce a reorganization in language lateralization independent of the effect of lesion. 3. Bilateral epileptic activity can prevent a reorganization of memory functions contralateral to the seizure onset region. 4. Injury of the right upper limb can induce a left-to-right shift of language lateralization. Conclusions - Our results may have implication during neurorehabilitation process and neurosurgical interventions. Participation of malformations of cortical development in cognitive functions should keep in mind during surgery. Reorganization of speech- and memory functions should also be considered during operations of central nervous system.
