AI Article Synopsis
- Predictive auditory-motor synchronization is essential for music and involves anticipating sounds with rhythmic movements, previously thought to be unique to humans.
- Researchers trained 8 rats to synchronize their licking to metronome beats ranging from 0.5 to 2 Hz, demonstrating they could predictively coordinate their actions with auditory cues.
- Using advanced modeling techniques, the study showed that rats used predictive control rather than reactive strategies, suggesting that this ability might be more common among mammals than previously believed.
Article Abstract
Predictive auditory-motor synchronization, in which rhythmic movements anticipate rhythmic sounds, is at the core of the human capacity for music. Rodents show impressive capabilities in timing and motor tasks, but their ability to predictively coordinate sensation and action has not been demonstrated. Here, we reveal a clear capacity for predictive auditory-motor synchronization in rodent species using a modeling approach for the quantitative exploration of synchronization behaviors. We trained 8 rats to synchronize their licking to metronomes with tempi ranging from 0.5to 2 Hz and observed periodic lick patterns locked to metronome beats. We developed a flexible Markovian modeling framework to formally test how well different candidate strategies could explain the observed lick patterns. The best models required predictive control of licking that could not be explained by reactive strategies, indicating that predictive auditory-motor synchronization may be more widely shared across mammalian species than previously appreciated.
