In a recent study published in the journal Nature Neuroscience shows that pregnant women lose gray matter in areas of the brain that deal with people feelings. The study conducted MRI scans before pregnancy and after giving birth on a group of fathers and first-time mothers. The mothers showed a loss of gray matter while the fathers remained unchanged.Robert Froemke, a neuroscientist, from New York University’s Langone Medical Center, compared the process top “spring cleaning”. However, the loss, rather than diminish this area of brain processing, appears to make it more efficient, enabling improved interpretation of their babies’ needs and emotions, and therefore increasing their maternal attachment.
