## 4 Discussion  
The objective of our study was to evaluate changes of intracerebral activity using electromagnetic tomography (sLORETA) that arise during reflex locomotion stimulation of the breast zone. The analysis found statistically significant differences in the frequency bands alpha-2, beta-1, and beta-2 between actual stimulation and the resting condition prior to stimulation in BAs 6, 7, 23, 24, and 31 and between the resting condition after the stimulation was terminated and the resting condition prior to stimulation in the frequency bands alpha-1, alpha-2, beta-1, and beta-2 in BAs 3, 4, 6, and 24. It follows from the data we obtained that the reflex locomotion stimulation (VOJTA CE X PRE CE) especially influenced the secondary/supplementary brain centers and the areas that are functionally associated with them. The activity of the premotor and supplementary motor cortex (BAs 6, 23, and 24) suggests the phase of movement planning and preparation. The functions of Brodmann Area 6 are especially preparation and planning of voluntary movements [24,25]. Brodmann Area 6 further contains the cortical supplementary motor area (SMA), which participates in movement programming and planning. The SMA is also associated with motor activity depending on the internal state of the organism [25, 26, 27, 28, 29, 30]. BA

The activity of BA 24 is also associated with attention [25; 31; 32]. Premotor and supplementary cortex areas have already demonstrated activity in movement planning or only in the mere idea of movement [24; 25; 27]. Electrical stimulation of the premotor cortex elicits coarse motor activity with a complex synergistic character. Electrical stimulation of the supplementary cortical area elicits complex movements, rhythmic movements of the limbs, and rotational movements [29; 33; 34]. The change in the activity of the secondary sensory cortex in BA 7 can be a reaction to the perception of pressure caused by reflex locomotion stimulation [35; 36], though the area reacting to somatosensory stimuli is especially the primary sensory cortex (BAs 1, 2, and 3) [2; 37; 9; 10; 37; 38]. This area further reacts to painful and non-painful stimuli, especially when the subject concentrates on the location or intensity of the stimuli [35; 39; 40]. The intense non-painful pressure stimulus, lasting several minutes, was generated during the reflex locomotion stimulation. It is exactly this pressure stimulation that can be the reason why we observed changes in BA 7 when the condition prior to stimulation was compared with that during stimulation. The activation changes in BA7 may also correlate with the finding of cortisol level changes in the saliva of infants after the reflex locomotion stimulation [41].
