“…Acquired musical anhedonia is likely even rarer. Most work on acquired musical anhedonia has been individual case studies, although one large group study (approximately 80 patients with focal brain damage) indicated only one possible case of acquired musical anhedonia …”

“…Only one prior neuropsychological study has attempted to identify musical anhedonia in a large group of patients with focal brain damage. Belfi and colleagues studied 78 patients with focal brain damage to a wide variety of brain regions . Patients completed the BMRQ to assess their current musical reward state, as well as a retrospective questionnaire of their musical behaviors and feelings prior to and following their brain injury.…”

“…Most work on acquired musical anhedonia has been individual case studies, although one large group study (approximately 80 patients with focal brain damage) indicated only one possible case of acquired musical anhedonia. 50 One defining aspect of musical anhedonia is that an individual classified as musically anhedonic must show normal hedonic responses to other rewarding stimuli. For example, individuals with musical anhedonia display typical responses to other rewarding stimuli, including visual art, emotional (nonmusical) sounds, and monetary reward.…”

“…A recent group-level study investigated the connectivity between the STG and NAcc, via the OFC, and how this connectivity varied as a function of individual differences in musical reward. 60 The authors identified a relationship between musical 61 Case Insula/amygdala LH Satoh et al 46 Case Temporoparietal, frontal RH Hirel et al 62 Case Superior temporal gyrus RH Satoh et al 52 Case Putamen RH Belfi et al 50 Group n/a n/a reward, as measured by the BMRQ, and connectivity between the STG and OFC, in a tract that likely passes through the aIns. This relationship was observed only in the right hemisphere-individuals with musical anhedonia showed higher levels of axial diffusivity in this pathway.…”

“…Belfi and colleagues studied 78 patients with focal brain damage to a wide variety of brain regions. 50 Patients completed the BMRQ to assess their current musical reward state, as well as a retrospective questionnaire of their musical behaviors and feelings prior to and following their brain injury. As there is no standard threshold for diagnosing acquired musical anhedonia following brain damage other than subjective report by the patient, participants in this study were classified as musically anhedonic if they scored more than 1.5 SD below the mean on either the BMRQ or the retrospective questionnaire, while subsequently presenting normally on a scale to measure generalized anhedonia.…”

Music frequently elicits intense emotional responses, a phenomenon that has been scrutinized from multiple disciplines that span the sciences and arts. While most people enjoy music and find it rewarding, there is substantial individual variability in the experience and degree of music‐induced reward. Here, we review current work on the neural substrates of hedonic responses to music. In particular, we focus the present review on specific musical anhedonia, a selective lack of pleasure from music. Based on evidence from neuroimaging, neuropsychology, and brain stimulation studies, we derive a neuroanatomical model of the experience of pleasure during music listening. Our model posits that hedonic responses to music are the result of connectivity between structures involved in auditory perception as a predictive process, and those involved in the brain's dopaminergic reward system. We conclude with open questions and implications of this model for future research on why humans appreciate music.

There are pronounced differences in the degree to which individuals experience music-induced pleasure which are linked to variations in structural connectivity between auditory and reward areas. However, previous studies exploring the link between white matter structure and music reward sensitivity (MRS) have relied on standard diffusion tensor imaging methods, which present challenges in terms of anatomical accuracy and interpretability. Further, the link between MRS and connectivity in regions outside of auditory-reward networks, as well as the role of musical training, have yet to be investigated. Therefore, we investigated the relation between MRS and structural connectivity in a large number of directly segmented and anatomically verified white matter tracts in musicians (n = 24) and non-musicians (n = 23) using state-of-the-art tract reconstruction and fixel-based analysis. Using a manual tract-of-interest approach, we additionally tested MRS-white matter associations in auditory-reward networks seen in previous studies. Within the musician group, there was a significant positive relation between MRS and fiber density and cross section in the right middle longitudinal fascicle connecting auditory and inferior parietal cortices. There were also positive relations between MRS and fiber-bundle cross-section in tracts connecting the left thalamus to the ventral precentral gyrus and connecting the right thalamus to the right supplementary motor area, however, these did not survive FDR correction. These results suggest that, within musicians, dorsal auditory and motor networks are crucial to MRS, possibly via their roles in top-down predictive processing and auditory-motor transformations.
