> 
> "On average, the researchers found new fathers lost a percentage or two of cortical volume following the birth of their first child.
> 
> "This shrinkage was mainly confined to an area of the brain known as the 'default mode network', which is associated with parental acceptance and warmth.
> 
> "At first, a loss in cortical volume might sound like a bad thing, but it can actually indicate a refinement of the brain that makes connecting with a child more powerful and efficient.

> "Similar cortical losses in mothers, for example, are associated with greater neural responses to a child and stronger child-parent attachment,

> "They did, however, show signs of brain plasticity in their cortical gray matter, which is largely involved in social understanding – and the researchers also found pronounced reductions in the visual system's volume.

> "More research on this visual brain region and its role in parenthood is needed, but the findings do align with a recent study in 2020 that found fathers are better at visual memory tasks than those men without children.

> "'These findings may suggest a unique role of the visual system in helping fathers to recognize their infants and respond accordingly, a hypothesis to be confirmed by future studies," the authors of the new paper write."
