1. Identification of single motor units in ultrafast ultrasound image sequences of voluntary skeletal muscle contractions
Abstract : The central nervous system controls human force production by successive recruitment of motor units in the skeletal muscles and changing their neural firing rate. The motor unit comprises a motoneuron, its innervated muscle fibers, and its axons. READ MORE

2. Muscle Thixotropy : Implications for Human Motor Control
Abstract : Human skeletal muscles possess thixotropic, i.e. history-dependent mechanical properties. This means that the degree of passive muscle stiffness and resting tension is dependent on the immediately preceding history of contractions and length changes. READ MORE

3. High-Density Electromyography-Based Methods for Joint Torque Prediction and Motor Unit Behavior Observation
Abstract : Electromyography (EMG) is a technique that measures the electrical activity of muscles. It reflects muscle activation and provides an interface to the central nervous system at the level of the muscle or individual motor units, which helps us understand the mechanisms of muscle force production, control, and coordination.

4. Classification of muscle stretch receptor afferents in humans
Abstract : The response patterns of human stretch receptors in the finger extensor muscles of the forearm were studied using the microneurography technique. Single-unit recordings were obtained from one-hundred and twenty-four afferents. READ MORE

5. Neuromuscular adaptations to muscle fatigue during submaximal isometric contractions in man
Abstract : During a sustained contraction, the force producing capacity of a muscle gradually decreases. In order to maintain a constant force output, the neuromuscular system has to adapt to the contractile fatigue process. READ MORE
