Cortical thickness regions of interest. Starred regions are areas in which higher-fit children showed decreased cortical thickness compared to lower-fit children. (credit: Laura Chaddock-Heyman et al./PLOS ONE) A new study reveals that 9- and 10-year-old children who are aerobically fit tend to have significantly thinner gray matter than their “lower-fit” peers.

The study suggests, but … more…
