This synchrony has its origin mainly in the descending communication in corticospinal pathways between primary motor cortex (M1) and muscles. This tutorial replicates the processing pipeline and analysis presented in the [[https://www.fieldtriptoolbox.org/tutorial/coherence/|Analysis of corticomuscular coherence]] FieldTrip tutorial. <> == Background == [[Link-tocnx-tutorial|Coherence]] is a classic metric to evaluate the synchrony between two signals. Previous studies (conway 1995, review: https://www.frontiersin.org/articles/10.3389/fnhum.2019.00100/full) have reported the use of coherence to study the connectivity between the primary motor cortex and muscles. The results of such studies, show synchronized activity in the 15–30 Hz range during maintained voluntary contractions.
