Teen Brain Less Discerning of Threat vs. Safety, More Vulnerable to Stress

Admin Fri Apr 29, 2011 12:00 pm

Teen brains rely on early-maturing brain structures that process fear differently than adult brains, according to an NIMH-funded study.

Important Significance of this study:
The findings suggest that teen brains rely primarily on the hippocampus and right amygdala, brain structures that mature earlier in development and which are responsible for basic fear responses.
In contrast, adults show more focused brain activity in prefrontal regions, which mature later in development. These regions are also involved in making more reasoned judgments about what is actually dangerous from what is safe.
