PMID-11081826 EMG activation patterns during force production in precision grip. III. Synchronisation of single motor units.
- synchronization observed in 78% of intrinsic finger muscles (within the hand itself) and 45% of extrinsic finger muscles.
- force increase was not necessarily correlated to increased synchronization; rather, high synchronization occurred at low force production.
- instrinsic muscles have higher force sensitivity & higher recruitment thresholds.

Dr. hepp-Raymond himself seems to be a prolific researcher, judging from his pubmed search results. e.g.:
- PMID-18272868 Absence of gamma-range corticomuscular coherence during dynamic force in a deafferented patient.
- quote: proprioceptive information is mandatory in the genesis of gamma-band CMC (corticomuscular coherence) during the generation and control of dynamic forces.
