Questions and Answers

How does the regulation of the limbic system change from adolescence to early adulthood?

It becomes entirely independent of the prefrontal cortex.

It is regulated better due to increased connections. (correct)

What significant brain change occurs during early adulthood aside from limbic system regulation?

Decrease in the connectivity between hemispheres.

Reduction in the size of the amygdala.

Stabilization of the overall brain weight.

Expansion of the corpus callosum. (correct)

Study Notes

Brain Development in Early Adulthood

The limbic system, responsible for emotions and decision-making, is better regulated by the prefrontal cortex as connections increase.
Increased connectivity leads to improved emotional control and decision-making abilities during early adulthood.
The corpus callosum, which facilitates communication between the brain's hemispheres, undergoes expansion during this period, enhancing cognitive functions.
Brain weight continues to increase in early adulthood, indicating ongoing structural development and maturation.
