In neuroscience, the<unk>  is a collection of brain structures which attempts to regulate and control behavior by inducing pleasurable effects. The major neurochemical pathway of the<unk>  involves the mesocorticolimbic pathway (MCLP). The major chemical in the<unk>  is dopamine.
A<unk>  is a process that reinforces behavior — something that, when offered, causes a behavior to increase in intensity.<unk>  is an operational concept for describing the positive value an individual ascribes to an object, behavioral act or an internal physical state. Primary<unk> s include those that are necessary for the survival of the species, such as food, water, and sex. Some people include shelter in primary<unk> . Secondary<unk> s derive their value from the primary<unk>  and include money, pleasant touch, beautiful faces, music etc. The functions of<unk> s are based directly on the modification of behavior and less directly on the physical and sensory properties of<unk> s.<unk> s induce learning, approach behaviour and feelings of positive emotions.
