No wait! That isn’t a setup line for a punchline. A recent study shows that nurturing a child early in life may help him or her develop a larger hippocampus, the region of the brain that is important for learning, memory and stress responses.
Brain images have now revealed that a mother’s love physically affects the volume of her child’s hippocampus. In the study, children of nurturing mothers had hippocampal volumes 10 percent larger than children whose mothers were not as nurturing. And research has suggested a link between a larger hippocampus and better memory.
One of the study authors had this to say; “We can now say with confidence that the psychosocial environment has a material impact on the way the human brain develops.” Dr. Joan Luby, the study’s lead researcher and a psychiatrist at the Washington University School of Medicine in St. Louis, MO said, “It puts a very strong wind behind the sail of the idea that early nurturing of children positively affects their development.”
