The paper compares neural coupling in motor units during index finger flexion and precision pinch tasks, finding stronger nonlinear coupling during pinch.

This paper develops a method to assess neural control of shoulder muscles using HDsEMG and robotic arm data, revealing task-specific activation patterns and motor unit behavior.

This study examines how varying rectus femoris length affects motor unit discharge rates in vasti muscles during isometric contractions, finding increased discharge rates at low force but not high force.

This study uses HDsEMG to show that corticospinal transmission during rTMS is bandpass-like, with strongest transmission between 20-50 Hz and frequency-specific synaptic input increases.

The paper examines changes in neural drive during motor skill acquisition, finding reduced alpha band common synaptic oscillations correlate with performance improvements in vastus lateralis but not vastus medialis.

This study examines motor unit discharge rates in hand muscles during different tasks, finding task- and muscle-specific rate coding patterns.

This study compares motor unit properties in proximal and distal regions of the biceps femoris long head during isometric tasks, finding greater distal activation due to action potential characteristics, not central modulation.

The paper examines how common synaptic inputs to spinal motor neurons change during grasping versus less functional hand tasks, finding reduced alpha band coherence and improved force steadiness during grasping.

The paper uses PCA and FA to show a single low-dimensional motor unit component explains most force oscillations during repetitive isometric tasks.

This study shows that short-term skill acquisition in a force-matching task involves reduced alpha band neural oscillations and increased coupling between force and target oscillations.

This study examines how muscle length affects synaptic oscillations and force output in motor neurons, finding reduced alpha band oscillations with increased muscle length.
