The fact that dopamine amplifies some signals and mutes others in the __________ suggests that it is part of the process of reinforcement in the brain.

Question

Quizplus · Accepted Answer

The nucleus accumbens is a key region involved in reward and addiction pathways, and dopamine plays a crucial role in reinforcing certain behaviors by amplifying signals in this region while muting others. Therefore, dopamine's involvement in the nucleus accumbens suggests it is a part of the reinforcement process in the brain. The other options, pons and central sulcus, are not primarily involved in reward pathways, and the putamen is not directly involved in reinforcement but rather in motor control and learning.
