The Reward Circuit - in depth This control starts with opioids' ability to affect activity in the reward circuit, which, in turn, acts on the more primitive sections of the brain, such as the limbic structures. This process allows opioids a direct line to those areas of the brain most likely to control behavior in times of stress.

- Normally, there are brain cells (neurons) in the human brain that produce dopamine. These neurons concentrate in a particular area of the brain, called the substantia nigra. Dopamine is a chemical that relays messages between the substantia nigra and other parts of the brain to control movements of the human body.

How Addiction Hijacks Our Reward System It is a hijacking of the brain circuitry that controls behavior, so that the addict’s behavior is fully directed to drug seeking and use. With repeated drug use, the reward system of the brain becomes subservient to the need for the drug. Brain changes have occurred that will probably inﬂuence the addict for life, regardless of whether or not he continues to use the drug.

- The Dopamine Pathways. Dopamine is the neurotransmitter used by the reward pathway (also called the mesolimbic pathway, which is closely linked with the mesocortical pathway). But there are two other important pathways in the brain that use dopamine: the nigrostriatal pathway and the tuberoinfundibular pathway. Generally, drugs that affect dopamine levels affect all three of these pathways. Nigrostriatal pathway: Substantia nigra to striatum. 1  Motor control.

Dopamine In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. The brain includes several distinct dopamine pathways, one of which plays a major role in reward-motivated behavior. Most types of reward increase the level of dopamine in the brain, and many addictive drugs increase dopamine neuronal activity. Other brain dopamine pathways are involved in motor control and in controlling the release of various hormones. These pathways and cell groups form a dopamine system which is neuromodulatory.

- The cerebellum (Latin for little brain) is a region of the brain that plays an important role in motor control.It may also be involved in some cognitive functions such as attention and language, and in regulating fear and pleasure responses, but its movement-related functions are the most solidly established.he name cerebellum is a diminutive of cerebrum (brain); it can be translated literally as little brain. The Latin name is a direct translation of the Ancient Greek παρεγκεφαλίς (parencephalis), which was used in the works of Aristotle, the first known writer to describe the structure.

- Iran tests 'super-fast' torpedo. The missile was fired from a boat into the Gulf towards a target. Iran has tested what it says is the world's fastest underwater missile, designed to elude radar and destroy enemy submarines. National TV programmes were interrupted to show footage of the missile being fired into the Gulf and destroying a derelict ship.

Background Nicotine also causes an increase in the release of dopamine from neurons located in the limbic system. Dopamine is a neurotransmitter responsible for carrying messages about pleasurable feelings. The result is stimulation of the “reward system” in the brain, which causes feelings of pleasure. The reward system is a circuit in the brain that carries messages about pleasure.

Chapter 3 - The Brain As discussed before the reward pathway, located in the limbic system, is primarily made up of core structures that are connected by the median forebrain bundle (MFB): the nucleus accumbens (NA), the ventral tegmental area (VTA), the ventromedial and lateral nuclei of the hypothalamus, and the amygdala (1,2,3,7). The NA and the VTA are the most ...

Introduction to Psychology âPSY101 WHAT IS PSYCHOLOGY? THE PLEASURE CENTRES AFFECTED BY DRUGS. The nucleus accumbens definitely plays a central role in the reward circuit. Its operation is based chiefly on two essential neurotransmitters: dopamine, which promotes desire, and serotonin, whose effects include satiety and inhibition.Many animal studies have shown that all drugs increase the production of dopamine in the nucleus accumbens, while reducing that of serotonin.ocated in the midbrain, at the top of the brainstem, the VTA is one of the most primitive parts of the brain. It is the neurons of the VTA that synthesize dopamine, which their axons then send to the nucleus accumbens.
