Was Steven Pinker right after all? [Part 2]
Pinker’s idea may actually be a very fruitful hypothesis whose significance has wrongfully gone unacknowledged because of all the criticism it elicited. After all, the purely evolutionary explanations for the origins of music largely overlook the experience of music we all share: the pleasure we derive from it, not only from the acrobatics of making it but also from the act of listening to it.
Last week Science published a study (a follow-up of Salimpoor et al., 2011) in which Canadian researchers were able to show precisely that: Music can arouse feelings of euphoria and craving, similar to tangible rewards that involve the striatal dopaminergic system. They were able to show that intense pleasure in response to music can lead to dopamine release in the striatal system, most notably the nucleus accumbens. And, more importantly, the anticipation of an abstract reward can result in dopamine release in an anatomical pathway distinct from that associated with the peak pleasure itself.
