Pregnancy changes the brain for up to 2 years

Structural changes in the brains of pregnancy women are so distinct that mothers can be identified just by a look at their brain scans, according to a study conducted in Spain and published in the journal Nature Neuroscience. Pregnant mothers experience significant changes in the areas of their brains responsible for social cognition and the ability to attune with others, suggestive as required for maternal bonding. Furthermore, these changes lasted for at least 2 years; the only change in these areas was a partial return to the pre-pregnancy state in terms of memory.
