Synaptic pruning is a natural process that occurs in the brain between early childhood and adulthood, during this process, the brain eliminated extra synapses.

The process in which myelin is wrapped around neuronal axons and acts as a layer of insulation.

The amygdala is located in the medial temporal lobe

What does it control?

It is located in the frontal lobe

What does it do?
It is in charge of reasoning/thinking before we act.

How is it affected by adolescence?
As the prefrontal cortex developed, teenagers can reason better, develop more control over impulses and make judgments better. This makes substance use even more dangerous in adolescence as the prefrontal cortex is the last part of the brain to fully develop.
