Ample evidence has supported the protective effect of physical activity on wide range of cognitive functions. The role of attention disengagement in learning has steered the research towards further investigation of attention mechanisms. The studies investigating spatial attention have strengthened a functionally inhibitory role of alpha oscillations in attention. When attention is allocated to other hemifield, alpha activity increases in hemisphere ipsilateral to attended hemifield and decreases in hemisphere contralateral to attended hemifield. However, it remains unexplored whether physical activity induces adaptations in this alpha lateralization. The aim of this study was to characterize posterior alpha modulations in children with varying physical activity level in relation to allocation of attention. The subjects were divided into high fit (n=21) and moderate-to-low (mod-low) fit (n=26) groups according to their shuttle run test results. Posterior alpha activity was measured from 12\u201316 year old children using magnetoencephalography (MEG) while they performed a visuospatial attention task in which a cue was presented before the target-onset. In pre-target interval, the results showed increased alpha activity in the hemisphere ipsilateral to attended hemifield, whereas the alpha activity decreased relatively in the hemisphere contralateral to attended hemifield. Among all children (n=47), the modulation was significant at 300\u2013 1300 ms after cue-onset. In this study, the alpha modulation did not differ significantly between high fit and mod-low fit subjects. However, mod-low fit subjects showed a bias towards right visual hemifield in attention task within the first 500 ms after the cue-onset. In the time interval of 500\u20131000 ms after the cue-onset, the alpha modulation between the groups was similar in both hemispheres. In conclusion, the study showed that attention modulates alpha oscillations in 12\u201316 year old children. In addition, there was a trend for weaker rightward bias in high fit children, which might be utilized in the evaluation of the children\u2019s developmental level, since the rightward bias is typically observed from younger children and adults with attention deficits.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Jenni V\u00e4h\u00e4maa (jekavaha) on 2016-11-23 06:25:10.926778.
