Electrical activity of the brain during graphomotor activities: Case study

This paper shows findings resulting from a research on bioelectrical activity of the brain while performing graphomotor activity in a seven-year-old boy subject. Measurements of brain potential was carried out by the method of electroencephalography and the obtained data underwent the spectrum analyses in the band of alpha, beta and mu waves. The implemented case analyses confirmed and increase of the beta rhythm while performing graphomotor activities. The obtained results imply a complexity of the process of visual-motor integration and the importance of functional integration of the central nervous system as a precondition for generating a movement and motor control.
