ATLANTA - A new study suggested that some grandmothers may hold a deeper bond with their grandchildren than their own children.
James Riling of Emory University in Atlanta published the study in "The Royal Society" last week. His team recruited and surveyed 50 grandmothers with at least one biological grandchild between three and 12 years old.
They also measured the brain function as the participants viewed pictures of their grandchild, an unknown child, the same-sex parent of the grandchild and an unknown adult.RELATED: Indiana town will give you cash and ‘grandparents on demand’ if you move thereResearchers found that grandmothers viewing grandchild pictures activated parts of the brain that involved emotional empathy and movement.
