addictive drugs). When exposed to a rewarding stimulus, the brain responds by increasing release of the neurotransmitter dopamine and thus the structures associated with the reward system are found along the major dopamine pathways in the brain.

The term reward system refers to a group of structures that are activated by rewarding or reinforcing stimuli (e.g. addictive drugs).

The reward system is present in the brain to ensure that humans repeat life-sustaining activities such as eating food, drinking water and mating. When people take drugs or drink alcohol, however, it basically sends the system into overdrive. The Effects of Drug Abuse on the Reward System. Drugs cause a massive surge of dopamine in the brain Substance use disorders result from changes in the brain that can occur with repeated use of alcohol or drugs. The most severe expression of the disorder, addiction, is associated with changes in the function of brain circuits involved in pleasure (the reward system), learning, stress, decision making, and self-control.
The disturbance of that circuit is partially responsible for addictions and cravings. Addictive drugs act upon brain reward systems throughout these regions, although the brain evolved to react to natural rewards, such as food and sex, not substances such as cocaine or alcohol. Substances that introduce unnatural levels of dopamine over a period of time hijack the brain’s natural reward system, affecting many functions in the brain’s reward pathways.

Se hela listan på philosophynow.org The brain reward system is a brain circuit that causes feelings of pleasure when it's “turned on” by something we enjoy (see figure), like eating good food or being in love. Whenever this reward circuit is activated, our brains note that something important is happening that's worth remembering and repeating. Drugs activate the brain reward THE REWARD SYSTEM (3:27) The reward system in the brain is what helps us learn about positive aspects of the world around us. it motivates our behavior and guides decision making.
