Un nuevo estudio afirma que los niños que son criados con afecto desarrollan en un 10 por ciento el tamaño del hipocampo, una zona del cerebro encargada de la memoria.

La profesora de psiquiatría infantil Joan L. Luby aseguró que quedó comprobado que la crianza de un niño influye directamente en las dimensiones que adopta el hipocampo.

El estudio fue publicado por la revista Proceedings of the National Academy of Sciences (PNAS) y es el primero que relaciona el tamaño del cerebro infantil con la forma de crianza.

La científica abogó porque la sociedad tome más conciencia y realicen la crianza en torno al amor y la atención, ya que esto luego tendrá un impacto en el desarrollo de la persona.

A Parent’s Nurturing Results In Larger Hippocampus In Children

A recent study by child psychiatrists and neuroscientists at Washington University School of Medicine in St Louis, published online in the Proceedings of the National Academy of Sciences Early Edition, states that children whose mothers showed them love and affection from the very beginning have brains with a larger hippocampus, which is a key part of the brain involved with memory, stress response, and learning.

The hippocampus is a very important element of the brain. It is part of the limbic system and is largely involved in grouping together information from short term memory to long term, as well as aiding in spatial navigation. When the body is stressed, the brain triggers the autonomic nervous system, which releases stress hormones to help the body deal with stress. The hippocampus is the main area of the brain that helps with this response. Leading the research is author Joan L. Luby, MD, professor of child psychiatry. She says:

This study validates something that seems to be intuitive, which is just how important nurturing parents are to creating adaptive human beings. I think the public health implications suggest that we should pay more attention to parents’ nurturing, and we should do what we can as a society to foster these skills because clearly nurturing has a very, very big impact on later development.

The researchers used brain imaging technology on children aged 7 to 10 years, who had been involved in a previous study of preschool depression, which was conducted by Ludy and team about 10 years prior to the new study. The previous study examined 3 to 6 year olds who were showing signs and symptoms of depression, a different type of psychiatric distress, or were completely mentally healthy with no signs of psychiatric problems at all.
