Abstract
Background. Morphological changes of cerebral cortex and early aging of the brain may suggest altered bioelectrical activity reflected by the rhythms of beta and theta waves in children with Down’s syndrome. Results. The cognitive potential of children with Down’s syndrome treated with early neurostimulation using the Wrocław Rehabilitation Model (WMU) in infancy was higher than in Down’s children treated after the age of 3. during neurostimulation by the Vojta method increased amplitudes of beta wave rhythm were obtained, along with reduced theta amplitudes. Conclusion. The early neurostimulation of children with Down’s syndrome from the first months of life significantly improves their concentration and increases their mental activity, which helps them to achieve a better start in life.

Abstract
Background. The prospects for diagnostic application of tests of the brain’s magnetic activity have motivated new clinical research in cognitive and clinical psychology. The purpose of the present study was to examine the nature of the bioelectric activity of the brain in young persons after the application of low-frequency magnetic fields as compared to baseline and placebo results, and to determine if magnetic stimulation can modify the amplitudes of beta and theta waves, used to measure the degree of concentration of attention. Material and methods. The research involved 32 persons with attention disorders involving concentration (Group A) and 32 persons without such problems (Group B). The degree of concentration of attention was measured by an invasive CapScan EEG/EMG subsystem (Bio-feedback Systems Inc.), which simultaneously recorded the beta and theta wave amplitudes. During the tests these rhythms were measured at baseline, after administration of a placebo, and after magnetic stimulation. Results. The baseline beta and theta wave rhythms recorded on-line from both cerebral hemispheres by the CapScan EEG/EMG subsystem in both study groups showed varying amplitudes. Low-frequency, low-amplitude magnetic fields produced a positive impact on concentration. After analysis of the relation of the amplitudes of beta and theta waves, Group A was found to have results characteristic for deconcentration. There was little change after the placebo, but a statistically significant improvement of concentration after magnetic stimulation. Conclusion. Statistical analysis demonstrates that low-frequency magnetic fields modify beta and theta rhythms in favor of improved concentration, i.e., when the beta amplitudes rise, the theta amplitudes automatically fall. This suggests that the low-frequency magnetic fields generated by the Viofor JPS magnetostimulator markedly increase the degree of concentration, and by the same token conscious mental activity.
