The love and care given by grandmothers is something not every child receives, but those who do have their grannies around should feel lucky.conducted by the researchers at Emory University in the southern US state of Georgia has proven that grandmothers are hard-wired to care deeply about their grandchildren.
"They recruited areas of the brain that are involved with emotional empathy, and also areas of the brain that are involved in movement and motor simulation and preparation," said James Rilling, an anthropologist and neuroscientist who led the study. This might be linked to children' s cute appearance, scientifically known as "baby schema," which the young of many species share in order to evoke a caregiving response, said Rilling.Unlike other primates, humans are "cooperative breeders," which means mothers get help in rearing offspring.
"This is really the first look at the grand maternal brain," said Rilling, explaining that brain scan studies on the elderly normally focus on studying conditions like Alzheimer's disease. But he stressed that this finding was only an average and doesn't necessarily apply to any given individual.
