Summary

Muscle movement type influences brain-muscle communication speed. Isotonic exercises shift corticospinal oscillations to gamma range, while isometric exercises favor beta range, clarifying the beta-to-gamma coherence shift.

Area of Science:

  • Neuroscience
  • Motor Control
  • Human Physiology

Background:

  • Corticospinal coupling, measured by electroencephalography (EEG) and electromyography (EMG) coherence, links motor cortex activity to muscle output.
  • Beta-range coherence is observed during static contractions, while gamma-range coherence is associated with dynamic contractions, but the underlying reasons are unclear.

Purpose of the Study:

  • To investigate the relationship between different types of muscle contractions (isometric vs. isotonic) and the frequency range of corticomuscular coherence.
  • To explore the role of muscle dynamics and proprioception in the observed shift in corticomuscular coherence frequencies.

Main Methods:

  • Recorded 264-channel EEG and 8-channel lower limb EMG from eight healthy subjects during isometric and isotonic knee and ankle exercises.
  • Utilized Adaptive Mixture Independent Component Analysis (AMICA) to isolate EEG source signals.
  • Computed magnitude squared coherence between motor cortex electrocortical sources and lower limb EMG signals.

Main Results:

  • Significant beta- and gamma-range coherence were found between the contralateral motor cortex and lower limb EMG across all exercise types.
  • Gamma-range coherence was significantly higher during isotonic exercises compared to isometric exercises.
  • This indicates that active muscle movement modulates corticospinal oscillation speed.

Conclusions:

  • Isotonic contractions promote gamma-range corticospinal oscillations, whereas isometric contractions favor beta-range oscillations.
  • Muscle dynamics, including proprioception, may be a key factor driving the shift in corticomuscular coherence from beta to gamma frequencies, independent of visual-somatosensory integration demands.
