Nurturing a child early in life may help him or her develop a larger hippocampus, the brain region important for learning, memory and stress responses, a new study shows.
Previous animal research showed that early maternal support has a positive effect on a young rat's hippocampal growth, production of brain cells and ability to deal with stress. Studies in human children, on the other hand, found a connection between early social experiences and the volume of the amygdala, which helps regulate the processing and memory of emotional reactions. Numerous studies also have found that children raised in a nurturing environment typically do better in school and are more emotionally developed than their non-nurtured peers.
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. Research has suggested a link between a larger hippocampus and better memory.

How thinking about death can lead to a good life
Thinking about death can actually be a good thing. An awareness of mortality can improve physical health and help us re-prioritize our goals and values, according to a new analysis of recent scientific studies. Even non-conscious thinking about death – say walking by a cemetery – could prompt positive changes and promote helping others.
