MEG corticomuscular coherence

Authors: Raymundo Cassani

Corticomuscular coherence relates to the synchrony in the neural activity of brain's cortical areas and muscle.

This tutorial replicates the processing pipeline and analysis presented in the "Analysis of corticomuscular coherence" tutorial in the FieldTrip documentation.

[[|Coherence]] is a classic metric to evaluate the synchrony between two signals. Previous studies (xx, and xx) have reported the use of coherence to measure the connectivity between the primary motor acortex and musckles thorough the corticospional pathways.

The ?results confirm the synchronized activity in the primary motor cortex (measure with MEG), and the motor-unit activity (measured with EMG) in the beta range of frequencies during maintained voluntary contractions

Corticomuscular coherence has been of special interest in alpha band (about 10 Hz), in Beta band (15–30 Hz), and in Gamma band (35–60 Hz).
