Individual differences are known to modulate brain responses to music. Recent neuroscience research suggests that each individual has unique and fundamentally stable functional brain connections irrespective of the task they perform. 77 participants’ functional Magnetic Resonance Imaging (fMRI) responses were measured while continuously listening to music. Using a graph-theory-based approach, we modeled whole-brain functional connectivity. We then calculate voxel-wise eigenvector centrality and subsequently use it to classify gender and musical expertise using binary Support Vector Machine (SVM). We achieved a cross-validated classification accuracy of 97% and 96% for gender and musical expertise, respectively. We also identify regions that contribute most to this classification. Thus, this study demonstrates that individual differences can be decoded from brain responses to music using a graph-based method with near-perfect precision.

The chronnectome of musical beat
Toiviainen, Petri; Burunat, Iballa; Brattico, Elvira; Vuust, Peter; Alluri, Vinoo (Elsevier BV, 2020)Keeping time is fundamental for our everyday existence. Various isochronous activities, such as locomotion, require us to use internal timekeeping. This phenomenon comes into play also in other human pursuits such as dance ... -
Beauty is in the brain networks of the beholder : An exploratory functional magnetic resonance imaging study
Dai, Ruijiao; Toiviainen, Petri; Vuust, Peter; Jacobsen, Thomas; Brattico, Elvira (American Psychological Association, 2024)Only a few studies have explored the association between such aesthetic processes with brain activity and the related patterns of brain connectivity states. Here, we exploratorily applied a recent algorithm for extracting ... -
The naturalistic paradigm : An approach to studying individual variability in neural underpinnings of music perception
Alluri, Vinoo; Toiviainen, Petri (New York Academy of Sciences, 2023)Music listening is a dynamic process that entails complex interactions between sensory, cognitive, and emotional processes. The naturalistic paradigm provides a means to investigate these processes in an ecologically valid ... -
Processing of an Audiobook in the Human Brain Is Shaped by Cultural Family Background
Hakonen, Maria; Ikäheimonen, Arsi; Hultèn, Annika; Kauttonen, Janne; Koskinen, Miika; Lin, Fa-Hsuan; Lowe, Anastasia; Sams, Mikko; Jääskeläinen, Iiro P. (MDPI AG, 2022)Perception of the same narrative can vary between individuals depending on a listener’s previous experiences. We studied whether and how cultural family background may shape the processing of an audiobook in the human ... -
Discovering hidden brain network responses to naturalistic stimuli via tensor component analysis of multi-subject fMRI data
Hu, Guoqiang; Li, Huanjie; Zhao, Wei; Hao, Yuxing; Bai, Zonglei; Nickerson, Lisa D.; Cong, Fengyu (Elsevier, 2022)The study of brain network interactions during naturalistic stimuli facilitates a deeper understanding of human brain function. To estimate large-scale brain networks evoked with naturalistic stimuli, a tensor component ...
