Question

Quizplus · Accepted Answer

The nucleus accumbens is a key brain region involved in the reward pathway, which is activated in response to drugs of abuse. Even if Walter no longer enjoys the feelings produced by methamphetamine, the activation of the nucleus accumbens can still drive his strong desire to use the drug. The amygdala is involved in emotion regulation and processing, but not specifically related to drug addiction. The cannabinoid system is involved in the regulation of various physiological functions and behaviors, including pain and appetite. The hippocampus is important for memory and learning, but not specifically related to drug addiction.
