One of the main neurotransmitters in our reward system is the “pleasure” chemical dopamine. Dopamine is produced mainly in the mid-brain and then moves to other areas of the brain, such as the amygdala, which plays a big role in our emotional development. The most important reward pathway in brain is the mesolimbic dopamine system. This circuit (VTA-NAc) is a key detector of a rewarding stimulus. Under normal conditions, the circuit controls an individual’s responses to natural rewards, such as food, sex, and social interactions, and is therefore an important determinant of motivation and The problem is substance abuse leads to unnaturally high levels of dopamine activity in the brain’s reward system, changing how these structures work and leaving them unable to function normally without substance abuse. Fortunately, addiction treatment can help the brain’s reward system heal from the effects of substance abuse.
Additionally, other areas in the brain provide us with memories and emotional attachment to tasty foods. Dopamine …
The brain’s reward system reinforces behaviors associated with rewards and prevents behaviors leading to punishment. But, this system can go awry in some psychiatric disorders. For example, the lateral habenula, a major node in the brain’s reward circuitry, appears to encode punishment by inhibiting dopamine release. Deep in the brain there’s a region called the medial forebrain bundle (part of the brain’s system responsible for integrating reward and pleasure). This area activates every time reward exceeds expectations.

Se hela listan på steptohealth.com The reward or affective value of the stimulus is represented in Tier 2 brain regions, the orbitofrontal cortex and amygdala, and in the anterior cingulate cortex. In Tier 3 areas, such as medial prefrontal cortex area 10, choices or decisions about reward value are made (107, 114, 126). Top-down control of affective response The nucleus accumbens is a key structure of the mesocorticolimbic system that is linked to the anticipation of reward (25, 30, 31). Its activation suggests that baby schema is a positive incentive that provides motivational drive to caretaking behavior (10). A reward pathway, or reward system, refers to a group of brain structures that are activated by rewarding stimuli.
In animal studies, scientists found brain areas whose electrical stimulation was found to be rewarding. In fact, the animals would continuously press a lever to obtain this stimulation and stopped only when exhausted. Subsequent studies found similar areas in other animals, including humans.

Neuroscientists have been able to pinpoint the exact parts of the brain involved, with the help of the rats. Point to the cartoon on the right and explain that rats will also self-administer addictive drugs directly into their brains, but only into a specific area of the reward system.
