We aim to examine how educational attainment and intelligence (predicted by genetics) affect brain morphology (cortical surface area, thickness and volumes of subcortical structures) in individuals across the life course. We are aiming to examine how early we can observe the effects of educational attainment and cognitive ability on brain morphology by using cohorts of different ages, such as ABCD, Generation R, ALSPAC, IMAGEN, and UK Biobank. This can indicate whether brain plasticity exists in response to changing educational attainment/intelligence levels. We will also investigate how differences in brain morphology can affect one's educational attainment and/or intelligence, using summary-level data from the ENIGMA consortium.
