A new study by researchers from the Carlos III Health Institute in Madrid has found that first-time fathers lose up to 2% of their brain volume after their first child is born. Scientists don’t know why it happens, but they suggest that the change may make it easier for fathers to connect with their children.
The team used MRI scans to assess first-time fathers' brains, measuring their brain's volume, thickness, and structural properties. The results showed shrinking in the areas of the brain that handle social understanding and their visual systems.
