Overview

Investigations reveal neural dynamics encoding perceptual and motor aspects in macaques during tapping tasks, implying deeper understanding of rhythm synchronization mechanisms.

Key Points

  • This investigation aims to understand the neural population mechanisms involved in attending and synchronizing movements to external rhythms.
  • Recorded neural activity from the medial premotor cortex of two macaque monkeys
  • Conducted an attend-then-synchronize tapping task with visual metronomes
  • Analyzed neural trajectories and their dynamics during attention and tapping phases
  • Identified low-dimensional neural manifolds capturing population trajectories
  • Increasing amplitude and oscillatory strength observed during the attention epoch
  • Shift to a distinct manifold subspace during the transition from perception to tapping
  • More robust oscillatory structure was present in correct tapping trials compared to incorrect ones
