How does the brain’s reward system work?

In order to survive in different environments and continue to evolve, humans have developed increasingly sophisticated mechanisms linked to the changing characteristics of the environment. In this case, the brain is responsible for developing survival and adaptation mechanisms for the above habitats.

For this, it has a system called the reward system, which response to the natural saturation of basic survival such as food, water, and sex to survive. In this article, we want to explain how it works.

Brain reward system mechanisms
Reward systems are centers of the central nervous system that obey specific and natural stimuli. Regulated by neurotransmitters, they allow the person to develop acquired behaviors that respond to pleasant or unpleasant events.

This system consists of mesolimbic and mesocortical regions of the brain. Excessive stimulation of the latter, in processed individuals, leads to permanent biochemical changes that interfere with the dependence interaction, which may alter performance and response to environmental stimuli.

The rewards system is the most important in the development of addiction. Brain regions that make up the brain reward system are a segmental ventricular region, Accumbens nucleus, frontal lobster cortex, lateral hypothalamus.

These nuclei are connected to the brain in a circuit called a motor booster circuit, related to the stimulus functions (the limb) and the locomotives (motor).

How is addiction created?
Depending on many of the same genetic factors and traits, some people tend to be more addicted because others are more likely to be attacked by pathogens than others.

The latest research focuses on various neurotransmitters, as well as brain systems or pathways, such as the medium reward system, as key factors in the development of addictive symptoms.

Hereditary activities and harmful substances affect the brain through the reward system, which consists of nerve cells that release chemicals or neurotransmitters when stimulated.

Thus, the substances and abuse activities, which are always enjoyable, although harmful to the body, have been able to seize brain centers, for pleasure, to maintain the habit.
