- New research suggests that the phenomenon of 'baby brain' has a biological basis, with pregnant women experiencing an average decrease of nearly five per cent in grey matter volume – the part of the brain involved in processing information, emotions and empathy.
- Scientists from Spain's Bemother project found that this reduction in grey matter, particularly in areas related to social cognition, is conducive to helping mothers bond and care for their newborns more effectively.
- The study involved scanning 127 pregnant women before, during, and after pregnancy, comparing their brain changes to a control group of 32 non-expectant women.
- Researchers observed that more significant brain changes correlated with stronger maternal bonding, and rising oestrogen levels tracked closely with the reduction in grey matter.
- Although grey matter partially recovered six months postpartum, the extent of recovery was linked to a higher absence of hostility towards the baby and improved maternal mental well-being, facilitating adaptive attachment.
