“…Modeling approaches may provide clues that help to pinpoint functionally where these differences are. A Bayesian framework applied to sensorimotor synchronization [46,47] comprises 4 stages: measurement, estimation, production, and feedback, with the fitted parameters reflecting details about the underlying sensorimotor process responsible for producing the observed synchronization data.…”

Synchronizing movements to music is one of the hallmarks of human culture whose evolutionary and neurobiological origins remain unknown. The ability to synchronize movements requires 1) detecting a steady rhythmic pulse, or beat, out of a stream of complex sounds, 2) projecting this rhythmic pattern forward in time to predict future input, and 3) timing motor commands in anticipation of predicted future beats. Here, we demonstrate that the macaque is capable of synchronizing taps to a subjective beat in real music, and even spontaneously chooses to do so over alternative strategies. This contradicts the influential 'vocal learning hypothesis' that musical beat synchronization is only possible in species with complex vocalizations such as humans and some songbirds. We propose an alternative view of musical beat perception and synchronization ability as a continuum onto which a wider range of species can be mapped depending on their ability to perform and coordinate the general abilities listed above through association with reward.

We determined the intersubject association between the rhythmic entrainment abilities of human subjects during a synchronization-continuation tapping task (SCT) and the macro- and microstructural properties of their superficial (SWM) and deep (DWM) white matter. Diffusion-weighted images were obtained from 32 subjects who performed the SCT with auditory or visual metronomes and five tempos ranging from 550 to 950 ms. We developed a method to determine the density of short-range fibers that run underneath the cortical mantle, interconnecting nearby cortical regions (U-fibers). Notably, individual differences in the density of U-fibers in the right audiomotor system were correlated with the degree of phase accuracy between the stimuli and taps across subjects. These correlations were specific to the synchronization epoch with auditory metronomes and tempos around 1.5 Hz. In addition, a significant association was found between phase accuracy and the density and bundle diameter of the corpus callosum (CC), forming an interval-selective map where short and long intervals were behaviorally correlated with the anterior and posterior portions of the CC. These findings suggest that the structural properties of the SWM and DWM in the audiomotor system support the tapping synchronization abilities of subjects, as cortical U-fiber density is linked to the preferred tapping tempo and the bundle properties of the CC define an interval-selective topography.
