Thanks for making this point, especially with regards to pregnancy being a loaded discussion topic. In the original study I found it very interesting that the authors drew parallels between the "maturation" of a new mother's brain (grey matter reductions) and the brains of adolescents undergoing pregnancy. If this study replicates, I would love to see followup studies exploring measures of narcissism, time management, executive functioning and facial recognition over time in women shortly before, during and after pregnancy (and perhaps even two years afterwards). These are all areas in which adolescents experience significant variations in functioning when compared to the general population, and there could be a lot of fertile ground here. One other thought that strikes me is how the grey matter alterations could potentially impact teenage mothers. If the mother's brain has not left adolescence by the time she experiences pregnancy, it would be interesting to see how the grey matter alterations differ, considering the authors' comparison.
