According to research (described by, among others, Videnskab.dk), "mommy brain" is not a sign that one is becoming less intelligent. On the contrary, a fascinating restructuring takes place.
Studies show that the amount of grey matter in certain areas of the brain decreases during pregnancy and in the period after birth. This may sound alarming, but researchers compare it to the process that occurs during puberty: the brain is "tidying up" and fine-tuning neural networks. The purpose is to make the mother (or father) more sensitive to the child’s social signals and needs. It is, therefore, a form of "biological upgrade" for parenthood.
