Abstract
We analyze the influence of an external sound source in a network of FitzHugh–Nagumo oscillators with empirical structural connectivity measured in healthy human subjects. We report synchronization patterns, induced by the frequency of the sound source. We show that the level of synchrony can be enhanced by choosing the frequency of the sound source and its amplitude as control parameters for synchronization patterns. We discuss a minimum model elucidating the modalities of the influence of music on the human brain.

Summary
Synchronization phenomena are well-known regarding dynamical activities of the brain. We model the spiking dynamics of the neurons by the paradigmatic FitzHugh–Nagumo model, and investigate possible partial synchronization patterns induced by an external sound source, which is connected to the auditory cortex of the human brain. It is a well-known fact that an important feature of musical sound perception is tonal fusion [20]. Time delays due to propagation over the whitematter tracts have been shown to organize the brain network synchronization dynamics for different types of oscillatory nodes [33]. The subtle interplay of excitatory and inhibitory interaction is typical of the critical state at the edge of different dynamical regimes in which the brain operates [45], and gives rise to partial synchronization patterns which are not found otherwise
