Dynamic brain plasticity during the transition to motherhood.

Earlier research has established strong evidence for structural brain changes across pregnancy. Pritschet et al. now enhanced our understanding of pregnancy-induced brain plasticity by following one woman throughout her pregnancy and the postpartum period, revealing insights into the dynamics of grey and white matter alterations across the transition to motherhood.

Ventro-striatal reductions underpin symptoms of hyperactivity and impulsivity in attention-deficit/hyperactivity disorder.

Background: Models of attention-deficit/hyperactivity disorder (ADHD) classically emphasize the relevance of executive processes and, recently, reward circuits. The neural bases of reward processes have barely been explored in relation to this disorder, in contrast to extensive neuroimaging studies that examine executive functions in patients with ADHD. To our knowledge, no previous studies have analyzed the volume of the ventral striatum, a key region for reward processes in ADHD children.
