2014 NeuroImage  
An association between IQ (available for 91 participants) and brain volume change was observed, which was attributed to genes involved in both the variation in change in brain volume and in intelligence  ...  We address the question whether longitudinal changes in brain volume or in surface area in young adults are under genetic control and whether these changes are also related to general cognitive functioning  ...  Moreover, brain volume changes in the young adult brain are positively related to intelligence and this association is mediated through genes common to both intelligence and brain volume change.  ...

The obese brain as a heritable phenotype: a combined morphometry and twin study

C M Weise, P Piaggi, M Reinhardt, K Chen, C R Savage, J Krakoff, B Pleger
2016 International Journal of Obesity  
Background-Body weight and adiposity are heritable traits. To date it remains unknown whether obesity-associated brain structural alterations are under a similar level of genetic control.  ...  Twin data were analyzed by applying the additive genetic, common environmental and residual effects (ACE) model to determine heritability of brain regions that were associated with BMI.  ...  It is possible that at least some regional brain volume differences reflect central endophenotypes leading to unhealthy eating and excess adiposity.  ...
