Investigating emotion with music: an fMRI study.
Level 4 - case-series / case-control
Laboratory neuroimaging experiment in humans (by design analogy, not clinical CEBM)

What was done
Functional magnetic resonance imaging (fMRI) was used to measure neural responses while participants listened to pleasant (consonant) and unpleasant (permanently dissonant) musical stimuli designed to evoke emotion.
What was found
The abstract reports no numerical values, effect sizes, or test statistics. Unpleasant music contrasted with pleasant music showed activation in the amygdala, hippocampus, parahippocampal gyrus, and temporal poles. Pleasant music contrasted with unpleasant music showed activation in the inferior frontal gyrus (Brodmann's area 44, 45, 46), anterior superior insula, ventral striatum, Heschl's gyrus, and Rolandic operculum. Activations in all these structures, except the hippocampus, increased over time during stimulus presentation.
Why it matters
The study demonstrates that music-evoked emotional valence dissociates between limbic networks (for unpleasant stimuli) and reward or premotor-related circuits (for pleasant stimuli), while showing that musical emotion processing exhibits temporal dynamics during auditory presentation.
Limits
The abstract does not report the sample size, participant demographics, or musical training background. No quantitative statistical thresholds, coordinate locations, or effect sizes are provided, and it is unstated whether subjective behavioral ratings were collected to verify emotional responses during scanning.
