For white matter, less water diffusion means the tissue is more fibrous and compact - both desirable traits.&lt;br&gt;&lt;br&gt;Significant fitness-related differences were seen in several key white matter regions, including the corpus callosum which joins the brain's left and right hemispheres.&lt;br&gt;&lt;br&gt;Two others were the superior longitudinal fasciculus, a pair of structures connecting two of the four major lobes in the brain's cerebral cortex, and the superior corona radiata which links the cerebral cortex to the brain stem.&lt;br&gt;&lt;br&gt;&quot;All of these tracts have been found to play a role in attention and memory,&quot; said Dr Chaddock-Heyman.&lt;br&gt;&lt;br&gt;The research is reported in the journal Frontiers in Human Neuroscience.&lt;br&gt;&lt;br&gt;Although the team did not test the children's mental performance, previous research has demonstrated a link between aerobic fitness and increasing thinking ability.</div>
