Corticomuscular coherence

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

The origins of corticomuscular coherence seem to be communication in corticospinal pathways between primary motor cortex and muscles.

[2] Statistical significance of coherence is found as function of number of data segments with assumption of the signals' normal distribution.

Specific cortical oscillation patterns can be spatially filtered by the dendritic arbors of the corticospinal fibers to selectively shape the descending drive to the motoneurons in the spinal cord.

These traces appear as weak levels of beta band corticomuscular coherence which are consistent with those observed in physiology.
