Pleasure is part of hedonic well-being, with roots back to Epicurus 2000 years ago. With the new evolving neuroscientific methods of the late 20th and beginning of the 21st century, we are now able to study the biological components of pleasure. This thesis aims to review empirical studies on the neural correlates of pleasure, which can have important implications for well-being, and treatment of addiction and affective disorders. Recent studies have suggested that pleasure can be separated into coding and causing. Discoveries show that causing of pleasure is created in so called hedonic hot spots, areas of the brain that intensely creates pleasure in the shell of nucleus accumbens and in the ventral pallidum. Areas that codes pleasure on the other hand is represented into more cortical areas of the brain, including orbitofrontal cortex, anterior cingulate cortex and anterior insular cortex. There has been a growing understanding about how pleasure is represented in the brain, and a discussion on interpretations and limitations are provided followed by future research suggestions in the final section.
