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.

Motor development and motor resonance difficulties in autism: relevance to early intervention for language and communication skills

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, fear, and the placebo effect.

Basal ganglia. I like this image because it shows all the different names for the different parts of the basal ganglia, something that's often confusing.

Basal Ganglia [Image Source] The basal ganglia are nestled inside cortex, surrounding the thalamus (see image above). The striatum (part of the basal ganglia circuitry) is composed of the putamen,.

'If you have fallen asleep during a meeting, don't blame yourself: blame your neurons. Specifically, a set of neurons in a brain area known as the nucleus accumbens, which is a region known to play a role in motivation and reward.' - Ana Sandoiu These neurons make us fall asleep when we are bored:

A part of the brain linked to motivation and pleasure -- the nucleus accumbens -- also produce sleeps. New research suggests this is why boredom (the absence of motivating stimulation) makes us sleepy.
