In neuroscience, the reward system is a collection of brain structures which attempts to regulate and control behavior by inducing pleasurable effects. The neurological reward system is part of what makes reinforcement possible.
The major neurochemical pathway of the reward system in the brain involves the mesolimbic and mesocortical pathway. Of these pathways, the mesolimbic pathway plays the major role, and goes from the ventral tegmental area via the medial forebrain bundle to nucleus accumbens, which is the primary release site for the neurotransmitter dopamine. Dopamine acts on D1 or D2 receptors to either stimulate (D1) or inhibit (D2) the production of cAMP.
And yes, this is a C-P from a wikipage :P

The reward center of the brain is a network of structures primarily involving the mesolimbic pathway, including the ventral tegmental area (VTA), nucleus accumbens, and prefrontal cortex. This system is responsible for processing pleasure, motivation, and reinforcement in response to rewarding stimuli like food, sex, and drugs. Dysregulation of the reward center can lead to substance abuse, addiction, and other behavioral disorders.
brain, particularly in the mesolimbic pathway. This pathway involves the release of dopamine in response to pleasurable activities or substances, reinforcing the behavior that led to the reward. Over time, this can lead to cravings and compulsive drug-seeking behavior.
Some nicknames for the brain include "the grey matter," "the noggin," and "the cranium command center."
the hypothalamus
We experience fun because it activates the brain's reward system, releasing feel-good chemicals like dopamine. This motivates us to engage in activities that bring pleasure and satisfaction.
Dopamine is the neurotransmitter that drugs increase, leading to pleasurable feelings. It plays a key role in the brain's reward system and is associated with motivation, reinforcement, and pleasure.
