| Abstract: | [Purpose] The study analyzed the electroencephalographic (EEG) data of the centralcortical areas, during execution of the motor gestures of feeding, activation of thesystem of mirror neurons, and imagery between a right hemiparetic volunteer (RHV) and ahealthy volunteer (HV). [Subjects and Methods] The volunteers’ EEG data were recorded withtheir eyes open for 4 minutes while they performed five experimental tasks. [Results] Thealpha band, absolute power value of HV was lower than that of RHV. In the beta band,during the practice condition, there was an increase in the magnitude of the absolutepower value of HV at T3, possibly because T3 is representative of secondary motor areasthat work with cortical neurons related to planning and organizing sequence of movementsperformed by the hands. The gamma band is related to the state of preparation for movementand memory. The results of this study indicate that there was increased activation of thegamma frequency band of HV. [Conclusion] The findings of this study have revealed thechanges in pattern characteristics of each band which may be associated with the braininjury of the hemiparetic patient.Key words: Electroencephalography, Hemiparetic, Rehabilitation |
