Voilà, le concert de Godspeed You Black Emperor est désormais derrière moi.
Un grand moment, qui aura duré près de 2h30.
Ne m'aura manqué que la proximité avec la scène, comme lorsque je les avais vus en 2002 et 2003.
Un concert qui aura suscité quelques frissons...
Or, c'est là désormais un phénomène bien compris:
Une étude scientifique canadienne a récemment établi la corrélation entre le plaisir que peut provoquer l'écoute de musique chez certains sujets, les frissons et la sécrétion de dopamine.
[La dopamine est une substance (plus exactement un neurotransmetteur) produite par le cerveau en situation de plaisir, comme par exemple lors d'un repas, ou de prise de drogue.]
L'étude montre que deux zones différentes du cerveau sont activées, selon que le pic émotionnel d'un morceau survient, ou est anticipé.
Voici l'abstract de l'article, paru dans Nature.
Music, an abstract stimulus, can arouse feelings of euphoria and craving, similar to tangible rewards that involve the striatal dopaminergic system. Using the neurochemical specificity of [11C]raclopride positron emission tomography scanning, combined with psychophysiological measures of autonomic nervous system activity, we found endogenous dopamine release in the striatum at peak emotional arousal during music listening. To examine the time course of dopamine release, we used functional magnetic resonance imaging with the same stimuli and listeners, and found a functional dissociation: the caudate was more involved during the anticipation and the nucleus accumbens was more involved during the experience of peak emotional responses to music. These results indicate that intense pleasure in response to music can lead to dopamine release in the striatal system. Notably, the anticipation of an abstract reward can result in dopamine release in an anatomical pathway distinct from that associated with the peak pleasure itself. Our results help to explain why music is of such high value across all human societies.
L'article se termine par cet élargissement :
Dopamine is pivotal for establishing and maintaining behavior. 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. These results further speak to why music can be effectively used in rituals, marketing or film to manipulate hedonic states. Our findings provide neurochemical evidence that intense emotional responses to music involve ancient reward circuitry and serve as a starting point for more detailed investigations of the biological substrates that underlie abstract forms of pleasure.
Pour les curieux, les nostalgiques de la rigueur scientifique, ou ceux qui veulent tout simplement se confronter à de la littérature scientifique en bonne et due forme, l'étude complète est disponible au format pdf, et téléchargeable ici.
