Summary

Individual differences in temporal prediction for sensorimotor synchronization are linked to the dorsal premotor cortex (PMd). Higher PMd activity correlates with better predictive abilities and more accurate tapping to auditory rhythms.

Neuroscience

Background:

Sensorimotor synchronization relies on temporal prediction, but individual variations and their neural basis are poorly understood.
Understanding these variations is crucial for fields ranging from neuroscience to human-computer interaction.

Purpose of the Study:

To identify the neural correlates of temporal prediction ability during auditory-motor synchronization.
To investigate individual differences in prediction accuracy and their relationship with brain activity.

Main Methods:

Functional magnetic resonance imaging (7T) was used to scan 18 healthy volunteers.
Participants performed tapping tasks synchronized to isochronous, tempo-changing, and random auditory metronome beats.
Prediction ability was quantified using prediction/tracking ratios derived from tap timing and pacing events.

Main Results:

A higher prediction/tracking ratio, indicating stronger predictive tendency, was associated with more accurate and precise tapping.
The prediction/tracking ratio positively correlated with activity in the bilateral dorsal premotor cortex (PMd).
This suggests the bilateral PMd plays a key role in explaining individual variations in temporal prediction.

Conclusions:

The dorsal premotor cortex (PMd) is critically involved in generating internal models for auditory rhythm temporal prediction.
Activity levels in the PMd reflect the accuracy of these predictive models, which is essential for effective sensorimotor synchronization.
These findings highlight the PMd's role in individual differences in timing and rhythmic coordination.
