      Modulation of cortical function can be achieved via the D1, D2, D3 and D4 dopamine receptors, leading to the "fine tuning" of information processing. D1 and D2 are high in the striatum, D3 is located in the nucleus accumbens and D4 is high in the frontal cortex and limbic areas.

      Knowledge of the role of neurobiological pathways in pain, addiction, and placebo analgesia is evolving.(55) Dopamine neurons have been considered central to addiction and pleasure(77, 78) and can be conditioned to sensory cues. Those cues can subsequently both evoke dopamine neuronal activity and elicit cue-associated conditioned behavior.(27, 54)
