nucleus accumbens

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 nucleus accumbens (NA) is a small part of the brain that is important for motivation, pleasure, and addiction. Sometimes called the brain's “pleasure center,” this cluster of neurons modulates the effects of the neurotransmitter dopamine, on which many neural circuits depend. The nucleus accumbens is a link in the brain pathways that cause addiction and depression. Damage to this region of the brain causes a lack of motivation and inhibits addictive behavior.

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,.

The Nucleus Accumbens: A Comprehensive Review

There is increasing interest among functional neurosurgeons in the potential for novel therapies to impact upon diseases beyond movement disorders and pain. A target of increasing interest is the nucl

Music Prompts Numerous Brain Changes Linked to Emotions and Abstract Decision Making. Music triggers activity in the nucleus accumbens, a part of the brain that releases the feel-good chemical dopamine, which helps you make decisions.

Circadian genes Period 1 and Period 2 in the nucleus accumbens regulate anxiety-related behavior

It has been suggested for some time that circadian rhythm abnormalities underlie the development of multiple psychiatric disorders. However, it is unclear how disruptions in individual circadian genes.
