Anatomy of the Brain

Below are some neuroanatomy pictures to give you a visual context when reading the two journal articles “Is the Teen Brain Too Rational?“and “Adolescent Brain Development and Risk-Taking“.

Figure 1. Dorsolateral prefrontal cortex region

The dorsolateral prefrontal cortex region of the brain is one of the last regions of the brain to develop at the end of adolescence. Generally, maturation is observed as a reduction in size.

Figure 2. Grey Matter vs. White Matter

During adolescence, grey matter volume undergoes an overall decrease at puberty. In contrast, white matter increases exponentially during adolescents.

Figure 3. Limbic System

Increased frequency of risk-taking during adolescence is due to the developmental changes in the limbic system which is functionally more mature as compared to the pre-frontal cortex.
