This study shows that visuomotor feedback responses to hand and target motion can be independently modulated based on task-relevance, indicating two separate feedback pathways.

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 paper develops a physics-informed neural network model to simulate muscle spindle function, validated across species and datasets, revealing key drivers of variability in proprioceptive responses.

This study shows that local muscle pressure stimulates human muscle spindles in isometric conditions and enhances their responses during stretch.

The paper compares goal-directed modulation of stretch reflex gains between dominant and non-dominant upper limbs, finding weaker tuning in the non-dominant limb.

This study shows that congruent visual cues enhance motor adaptation by improving state estimation during learning of novel dynamics.

The paper investigates how preparatory modulation of stretch reflex gains is influenced by target direction, preparation duration, and assistive loading during goal-directed reaching.

The paper shows that muscle spindle afferents modulate their firing rate during movement preparation depending on the movement goal, indicating sensory involvement in movement planning.

This study investigates how task-dependent modulation of spinal and transcortical stretch reflexes relates to motor learning rate in a visuomotor adaptation task.
