Pleasures registration brain and addiction: Neurotransmitter dopamine

Among the functions of the brain is that of pleasures registration as and when they happen irrespective of their origin. It doesn’t matter whether they’re associated with a psychoactive drug, a monetary reward, a sexual encounter, or a satisfying meal. The fact is in the brain pleasurable principles has a distinct role of releasing the neurotransmitter dopamine in the nucleus accumbens, a cluster of nerve cells lying underneath the cerebral cortex. Dopamine release in the nucleus accumbens is so consistently tied with pleasure that neuroscientists refer to the region as the brain’s pleasure center.

All drugs of abuse, from nicotine to heroin, cause a particularly powerful surge of dopamine in the nucleus accumbens. The likelihood that the use of a drug or participation in a rewarding activity will lead to addiction is directly linked to the speed with which it promotes dopamine release, the intensity of that release, and the reliability of that release. Therefore addictive drugs provide a shortcut to the brain’s reward system by flooding the nucleus accumbens with dopamine. The hippocampus lays down memories of this rapid sense of satisfaction, and the amygdala creates a conditioned response to certain stimuli.

Brain pleasurable principle and drug addiction: Learning the process

Previously it was believed that an experience of pleasure alone was enough to compel people into consistent seeking of addictive elements or activities. However new research findings indicate that the situation may be more complicated. This is because dopamines are not only responsible for the experience of pleasure but are also playing a role in learning and memory which are the two key elements in the transition from liking something to being addicted to it. Currently, the philosophy about addiction is that dopamine interacts with another neurotransmitter, glutamate to take over the brain’s system of reward-related learning. Remember that this system has an important role in sustaining life because it links activities needed for human survival (such as eating and sex) with pleasure and reward.

Finally, it may interest you to note that the reward circuit in the brain may include areas involved with motivation and memory as well as with pleasure. Addictive substances and behaviors stimulate the same circuit and then overload it. And therefore repeated misuse of any addictive substances or behavior will cause nerve cells in the nucleus accumbens and the prefrontal cortex (the area of the brain involved in planning and executing tasks) to communicate in a way that couples liking something with wanting it, in turn driving us to go after it. That is, this process motivates us to take action to seek out the source of pleasure. This can be very unhealthy more so if the source of pleasure is drugs. Many often run to drugs for pleasure and as such, the prevalence of drug abuse is on the rise. We can choose individually and collectively to correct this by scheduling an appointment with doctor Dalal Akoury MD, who is a veteran addiction expert and also the founder of AWAREmed Health and Wellness Resource Center for help today.

Dopamine reward principal

Dopamine reward principal

Dopamine reward principal. In fact, all addictive drugs and activities release varying amounts of dopamine into the nucleus accumbens with stimulant drugs like cocaine and methamphetamine releasing the most

Dopamine reward principal: Mesolimbic pathway

When the brain’s reward center is activated, it releases dopamine which then creating a pleasing, enjoyable sensation primarily to motivate individuals into repeating these behaviors necessary for survival. The reason why this is happening is because dopamine has rewarded us with a pleasurable feeling. That in itself is a testimony that dopamine reward principle (master) is the fueling the human survival. With that understanding of the purpose and functioning of the brain’s reward system. It would be important that we interrogate its (dopamine reward master) functions a little bit further.

Dopamine reward principal: Ventral tegmental area (VTA)

The circuit most associated with pleasure and reward is the mesolimbic pathway which is located in the brainstem. The objective of this area of the brain is primarily concerned with basic survival. Within the mesolimbic pathway is an area called the ventral tegmental area (VTA). The VTA projects to the nucleus accumbens (thought to be the reward center). The neurotransmitter most commonly linked with the mesolimbic system is dopamine. Many people consider dopamine to be the driving force behind the human pursuit of pleasure. The release of dopamine is a pleasurable sensation. The release of dopamine motivates us to repeat behaviors or activities that prompted this release. This system’s purpose was to promote survival by rewarding life-sustaining behaviors such eating and procreation.

Dopamine reward principal: Nucleus accumbens

All addictive drugs and activities release varying amounts of dopamine into the nucleus accumbens with stimulant drugs like cocaine and methamphetamine releasing the most. However, when it comes to drugs like alcohol or heroin, the brain’s own opiate system (endorphins) also gets involved. Doctor Akoury MD and founder of AWAREmed Health and Wellness Resource Center reiterates that even though different forms of addictions have different effects in the nucleus accumbens, they share one common denominator, that is, they all activate the reward system which in turn motivates us to repeat those behaviors, even though they may be harmful. Besides what we have discussed about the concepts of reward, pleasure, and craving together, it is however very important to appreciate that there is a distinction between pleasure-seeking and drug seeking. Note that pleasure-seeking is all about the pleasurable, rewarding aspect of addiction while drug-seeking refer to the craving aspect of addiction. Dopamine may be more involved in drug-seeking (craving) component of addiction. The opiate (endorphin), GABA, or glutamatergic systems may be more involved in a pleasure-seeking aspect of addiction too.

Finally, pleasure-seeking and drug-seeking (cravings) are interrelated, yet distinct. Research has established that natural rewards (food, water, sex) typically lessen their influence on the reward system over time. As a behavior occurs more often, dopamine levels tend to decrease in the process. Psychologists call this habituation. This makes sense. Once you’ve eaten enough food, you don’t need to be rewarded for eating more food. Then you would be eating too much, or too much of one type of food. Therefore everyone needs to take heed of keeping the brain free from all attacks be it from substances or otherwise. Talking to the experts at AWAREmed Health and Wellness Resource Center under the able leadership of doctor Dalal Akoury should be your starting point.
