A large number of studies have shown that the brain reward system is activated for certain drugs (such as cocaine or heroin).
This reward system is another order People are curious and
This is because, by associating the feeling of pleasure with the body, it is a mechanism that enables us to associate certain situations with pleasure, which is actually a form of adaptation and an increase in survival
This circuit involves many brain regions, for example, the reward mechanism is attributed to a pleasant sexual relationship, and this pleasure makes us want to repeat this relationship again.
Actually, this is the most basic in our lives Even related to drug use. Or other reward activities such as sports. Although important, in this article, we explain the most basic aspects of the reward system.
What structure does the reward system involve?
The reward system is in the brain. In fact, it is not located in a specific area of the brain. Like most of our functions, it It is formed in different areas connected to each other to form a circuit.
Since our brain is an organ that is difficult to analyze and study, the understanding of these areas is very complicated. However, it has been shown that the areas involved in this reward system are :
- the covered area.
- the nucleus accumbens, which is part of the basal ganglia.
- hypothalamus and hippocampus.
- prefrontal cortex.
- pale core.
In summary, It can be said that most reward circuits are located in a circuit called the midbrain margin. The substance that activates this circuit is dopamine.
Under what circumstances is the reward system activated?
As we have already mentioned, rewards The system is actually an adaptive function.
That is, first of all, it takes care of aspects such as eating, drinking or having sex. The taste of food makes us happy, just like we drink water when we are thirsty or have sex. So , Stimulates the learning and repetition of these actions.
However, they are not the only functions inspired by the system. For example, we can play by , Exercise, and of course drugs to experience happiness. Many studies have shown that ingestion of cocaine and other substances can activate the circuit.
This inevitably makes us think about the risks of reward systems. Addiction is this wonderful The negative part of the adaptation mechanism.
How do drugs work on this system?
First, the use of drugs (such as cocaine or heroin) is voluntary. Usually, this is the result of curiosity, or is it our The result of social image created by material. However, you only need to take it once to activate our reward system. There is a strong sense of pleasure that makes us involuntarily want to use the drug again.
If the addiction is severe, the reward system can be changed. For example, people who are addicted to heroin will hardly be happy about taking the substance without taking other actions. In other words, the rest of the satisfaction is "closed."
However, it is important to know that a substance need not exist. There are many independent addictions, such as gambling. In the end, the results are actually the same.
The brain reward system is an extremely complex mechanism. It enables us to adapt and survive, becoming humans and a species. However, it also has a negative aspect, as it is one aspect that interferes with the mechanism of addiction.
