Aza Allsop Yale School of Medicine Aza Allsop is a physician, neuroscientist and musician studying how music affects our brains and, in turn, how it might be used to improve mental health. Music has long been considered a convener; Allsop’s work helps to show why. In a recent study, he and his colleagues found that when people sitting face-to-face heard pleasing bits of music, their brains became more biochemically active in areas associated with social processing.
