[Purpose] The study analyzed the electroencephalographic (EEG) data of the central
cortical areas, during execution of the motor gestures of feeding, activation of the
system of mirror neurons, and imagery between a right hemiparetic volunteer (RHV) and a
healthy volunteer (HV). [Subjects and Methods] The volunteers’ EEG data were recorded with
their eyes open for 4 minutes while they performed five experimental tasks. [Results] The
alpha 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 absolute
power value of HV at T3, possibly because T3 is representative of secondary motor areas
that work with cortical neurons related to planning and organizing sequence of movements
performed by the hands. The gamma band is related to the state of preparation for movement
and memory. The results of this study indicate that there was increased activation of the
gamma frequency band of HV. [Conclusion] The findings of this study have revealed the
changes in pattern characteristics of each band which may be associated with the brain
injury of the hemiparetic patient.
