In neuroscience, the reward system is a collection of brain structures and neural pathways that are responsible for reward-related cognition, including associative learning (primarily classical conditioning and operant reinforcement), incentive salience (i.e., motivation and "wanting", desire, or craving for a reward), and positively-valenced emotions, particularly emotions that involve ...
The mesolimbic pathway, sometimes referred to as the reward pathway, is a dopaminergic pathway in the brain. [1] The pathway connects the ventral tegmental area in the midbrain to the ventral striatum of the basal ganglia in the forebrain. The ventral striatum includes the nucleus accumbens and the olfactory tubercle. [2]
Investigation of the brain reward circuitry reveals that it consists of a distributed, multi-synaptic circuit that determines both BSR and natural reward function. [1] The natural drives that motivate and shape behavior reach the reward circuitry trans-synaptically through the peripheral senses of sight, sound, taste, smell, or touch.
The main dopaminergic pathways of the human brain. Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control.

The motivational system works largely by a reward–punishment mechanism. When a particular behavior is followed by favorable consequences, the reward mechanism in the brain is activated, which induces structural changes inside the brain that cause the same behavior to be repeated later, whenever a similar situation arises. Conversely, when a ...
Incentive salience is a cognitive process that grants a "desire" or "want" attribute, which includes a motivational component to a rewarding stimulus. [1] [2] [3] [9] Reward is the attractive and motivational property of a stimulus that induces appetitive behavior – also known as approach behavior – and consummatory behavior. [3]
“The brain changes, and it doesn’t recover when you just stop the drug because the brain has been actually changed,” Kreek explained. “The brain may get OK with time in some persons. But it’s hard to find a person who has completely normal brain function after a long cycle of opiate addiction, not without specific medication treatment.”
The limbic loop is a functional pathway of the basal ganglia, in which the ventral pallidum is involved. It (and the internal globus pallidus and substantia nigra pars reticulata) receives input from the temporal lobes, and the hippocampus via the ventral striatum.
