Electrophysiological indexes of eyes open and closed resting states conditions following the Quadrato Motor Training: a longitudinal study

摘要

Eyes closed (EC) and eyes open (EO) resting states are generally considered the brain stateswith the lowest level of arousal. However, recent studies showed that the resting brain activity is not astatic phenomenon, but is rather modulated by the incoming stimuli, producing differences in the neuralactivity. In the past, we showed that dynamic electrophysiological measures, such as coherence andfunctional connectivity, were modulated by Quadrato Motor Training (QMT) during the rsEEG withclosed eyes, while it particularly affects the alpha-power during the rsEEG recorded with open eyes. Herewe investigated the differences in the power spectrum between EC and EO following 3 months of QMT.To this purpose, we analyzed separately power spectrum, and the differences in the cortical generatorsusing eLORETA software. We found that QMT lead to an increased differentiation between EC and EOmainly in the beta frequency range, and most importantly a change in cortical generators related to alphaoscillation in the para-hippocampal gyrus and to beta activity bilateral in the frontal areas. These resultsshowed that QMT could positively contributes to sharpen the specialization during the different EC andEO brain states, refining their specific characteristics.
