White Matter Correlates of Musical Anhedonia: Implications for Evolution of Music
Loui and colleagues test an evolutionary claim about music as affective communication by comparing a special population against normal variation. They examine white matter connectivity in BW, a case of severe musical anhedonia, against a large sample of control subjects showing the normal range of reward sensitivity to music. Two results follow. Structural connectivity within the reward system predicted individual differences in musical reward across the large population, which the authors report as a first. And specific patterns of connectivity between auditory and reward systems were unusual in the extreme case. The paper presents this as support for and an extension of the Mixed Origins of Music theory, identifying multiple neural pathways by which music might operate as an affective signalling system. This publication cites it for the individual-differences finding and records both results as correlational, with the second resting on a single case.
