Music listening is a sophisticated behaviour that employs numerous networks of brain regions. Because music remains enjoyable later in life, it is often used in clinical settings with those with neurodegeneration. However, much is still unknown about how music listening adapts to reconfigurations in brain network dynamics related to healthy aging. This dissertation examines dynamic brain network activity during music listening in healthy adults. Network measures were analyzed with behavioural and stimulus data across three studies using a combination of hidden Markov modelling and partial least squares.The first study presents age- and preference-related differences in music listening in healthy younger and older adults using fMRI. Both age groups showed higher occupancy (the proportion of time a network was active) in a temporal-mesolimbic network while listening to self-selected music. Activity in this network was strongly positively correlated with liking and familiarity ratings in younger adults, but was more ambiguously correlated in older adults. Additionally, older adults showed a higher degree of correlation between liking and familiarity ratings consistent with past behavioural work on age-related dedifferentiation.The second study presents effects in a subset of the older adult group from the first study following an 8-week music listening intervention. Results showed higher occupancy in the temporal-mesolimbic network following the intervention suggesting that network activity can change in response to music-based interventions.The third study presents task differences in a music listening task in healthy young adults using EEG. In this study, participants listened to music while continuously rating either perceptual features in the musical signal, or emotional states induced by the music. Network activity in medial frontoparietal, pericentral, anterior frontal, and bilateral temporal networks was most strongly positively correlated with rudimentary features in the musical signal during the perceptual listening task. In the emotional task, transitions between networks were more positively correlated with low-arousal low-valence emotional states in anterior cingulate, frontal, and occipital networks.I discuss the implications of modelling music at different spatiotemporal scales with a particular focus on these findings' applicability for clinical research.
