Ventral Tegmental Area (VTA) is the area that synthesizes dopamine, which then sends to nucleus accumbens. Nucelus accumbens is the pleasure center, and it is stimulated by the neurotransmitter dopamine from VTA. VTA also sends dopamine to prefrontal cortex which regulates and controls these impulses. The locus coeruleus is the area packed with norepinephrine; and when stimulated by a lack of the addictive substance, will drives the person to do anything necessary to obtain a fix.
The Digital Invasion series at Westwood Community Church by Pastor Joel Johnson on April 26, 2015 How do we guard the Pleasure System of our brains The nucleus accumbens (NAcc), also known as the accumbens nucleus or as the nucleus accumbens septi (Latin for nucleus leaning against the septum or as The pleasure center)), is a collection of neurons and forms the main part of the ventral striatum. It is thought to play an important role in reward, pleasure, laughter, addiction, aggression…
Figure 2. Spine Heads of Neurons in the Nucleus Accumbens Core Enlarge 15 Minutes After a Cue-Induced Cocaine Relapse As shown by the blue arrows, the spine heads of medium spiny neurons in the nucleus accumbens core of cocaine-trained rats at 15 minutes after a cue-induced relapse (T = 15) are larger than those in the same rats before the induced relapse (T = 0).
