Brain Source Activity Changes During the Visual Training of the Imagination Viewed by sLORETA Imaging

Title: Brain Source Activity Changes During the Visual Training of the Imagination Viewed by sLORETA Imaging. Objectives: The research study aims to determine which changes in brain source activity occur before and after an intervention in the form of a three-week visual training of motor imagery. The electrical activity of the brain was recorded using scalp EEG and transferred to the sLORETA program, in which the source brain activity was evaluated. Methods: The research was concluded on 13 healthy subjects aged between 20-30 years. The Czech standardized version of The Vividness of Movement Imagery Questionnaire - 2 (VMIQ - 2) was used for the survey. The electrical activity of the brain was recorded using a scalp EEG Nicolet TM EEG Wireless Amplifier 32/64 by Natus Neurology. The research consisted of initial and control measurements, the measurement included several phases. First, an initial measurement took place, which always included measurements of resting EEG (5minutes eyes open and 5 minutes eyes closed), action observation in VR (3 minutes) and subsequent measurement of the motor imagery with eyes open (3 minutes). Between the individual measurements, there was a three-week visual training of motor imagery, which included action observation in VR and the individual motor imagery three..
