“Specifically:

  • among children from the lowest-income families, small differences in income were associated with relatively large differences in surface area in a number of regions of the brain associated with skills important for academic success, ”

  • Higher income was also associated with better performance in certain cognitive skills – cognitive differences that could be accounted for, in part, by greater brain surface area.
