The paper shows that axonal sodium currents drive doublets in motoneurons, amplifying force through nonlinear mechanisms, with neuromodulation affecting both timing and gain.

This study examines how task factors dynamically influence different components of the stretch reflex during a delayed-reach paradigm using multiple linear regression.

This study shows that spinal stretch reflexes adapt rapidly within a single session to support goal-directed movements, with no such adaptation observed with shorter preparatory delays.

This study investigates how different preparatory delays affect goal-directed tuning of stretch reflex gains in specific muscles during a delayed-reach task.

This study evaluates decoding algorithms for identifying motor unit discharges from ultrasound images under non-ideal conditions, finding they remain accurate despite varying twitch shapes and fusion.

This paper develops a model-based deconvolution method to estimate motor unit twitch parameters across different force levels, showing it can provide accurate estimates despite signal noise and missed firings.

This paper develops a method to accurately identify motoneuron discharges from ultrasound images across the full muscle cross-section, achieving high agreement with surface EMG decomposition.

This study compares two methods for identifying motor unit displacement areas using HDsEMG and UUS, finding that STICA offers more precise results despite higher computational complexity.

This study validates blind source separation methods on ultrafast ultrasound images to identify motor unit activity using EMG data from eleven participants.
