Significant alpha and theta power decreases of the EEG background activity in parietal and occipital regions of both hemispheres during mental training of motor skills (ideomotor swimming) are demonstrated. These decreases are attributed to the participation of the visual cortex during spatial imagination. Repetitive use of motor imagination during a session involves more cerebral regions in the neurophysiological process, which causes a significant diminution of alpha, theta, and beta-1 power in the central and frontal areas too. These changes can be interpreted as a special and more pronounced activation of regions implicated in the motor system.
