Prosocial behavior is defined as "voluntary behavior that benefits other companies" and appears in childhood and matures in adolescence.Humans tend to behave in a self-centered manner in early childhood, but prosocial behavior begins to appear in childhood, reaching the peak of prosocial development in early adolescence.

　Previous studies using magnetic resonance imaging (MRI) have shown that anterior cingulate gyrus is associated with adolescent social cognition, but adolescent prosociality and neurotransmitters and the brain. No association with functional networks was revealed.

　This research group measures the brain concentration of metabolites such as neurotransmitters in a large early pubertal subject population (10.5 to 13.4 years old) extracted from the general population (MRS). ) Was imaged.As a result, it was found that low GABA concentration in the anterior cingulate gyrus is highly prosocial, and that a strong functional network between the anterior cingulate gyrus and the posterior cingulate gyrus is highly prosocial.Furthermore, a low GABA concentration in the anterior cingulate gyrus indicates a stronger functional network between the anterior cingulate gyrus and the posterior cingulate gyrus. And the posterior cingulate gyrus have a strong functional network. ”→“ Highly prosocial. ”

　The results of this neuroscientific study of populations, or "population neuroscience," show that the metabolic dynamics and functional networks of the cranial nerves are associated with prosocial development in early adolescence. It is expected to deepen the understanding of the development of human subject value.
