It's about a study of what happens to the brain during build ups and crescendos and the anticipation thereof.
It talks about 'chills' that people feel at certain points in music.
Dopamine surged in one part of the striatum during the 15 seconds leading up to a thrilling moment, and a different part when that musical highlight finally arrived.
When I thought of the type of chill I get at such points, I had one there and then!
Did my brain secrete those chemicals purely from the memory of such an event? Yes.
That is the power of the mind!
I suppose it's meant to, so that good (or bad) associations can be formed and then relived in case we were in any doubt whether to try that type of experience again.
