Piloerection (goose bumps), the physical part of frisson. Frisson (UK: / ˈ f r iː s ɒ n / FREE-son, US: / f r iː ˈ s oʊ n / free-SOHN [1] [2] French:; French for "shiver"), also known as aesthetic chills or psychogenic shivers, is a psychophysiological response to rewarding stimuli (including music, films, stories, people, photos, and rituals [3]) that often induces a pleasurable or ...
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
These individuals experience feelings of depression, agitation and extreme discontent, leading them to indulge in habits that reinforce reward-seeking, such as increased sexual activity or overeating. [2] Individuals with higher reward dependence also look for more social approval, and are more inclined to succumb to peer-pressure.
Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. [1] While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning.
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]

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.
Pleasure is a component of reward, but not all rewards are pleasurable (e.g., money does not elicit pleasure unless this response is conditioned). [69] Stimuli that are naturally pleasurable, and therefore attractive, are known as intrinsic rewards , whereas stimuli that are attractive and motivate approach behavior, but are not inherently ...
