"Goose bumps, also called goose flesh, goose pimples, chill bumps, chicken skin, funky spots, Dasler Bumps, chicken bumps or the medical term cutis anserina, are the bumps on a person's skin at the base of body hairs which may involuntarily develop when a person is cold or experiences strong emotions such as fear, nostalgia, pleasure, awe, admiration or sexual arousal.......
Canadian researchers have suggested that when we are moved by music our brains behave as if reacting to delicious food, psychoactive drugs, or money.
The pleasure experience is driven by the chemical dopamine, which has been linked to addiction. It produces physical effects known as "chills" that cause changes in the skin's electrical conductance, heart rate, breathing and temperature. The responses correlate with the degree to which people rate the "pleasurability" of music.
The new research has shown that dopamine release was greatest when listeners had a strong emotional response to music. "If music-induced emotional states can lead to dopamine release, as our findings indicate, it may begin to explain why musical experiences are so valued,” wrote the scientists."
