Characterizing bilateral M1 excitability changes after learning a novel spatiotemporal coordination pattern

This study investigates how learning a novel coordination pattern affects motor cortex excitability, finding comparable behavioral improvements across bimanual and unimanual training without consistent neurophysiological correlates.

Ultrasonic Neuromodulation of the Human Hippocampus Reveals a Causal Role in Rapid Motor Memory Consolidation

This study uses ultrasound to modulate the human hippocampus and shows it affects motor skill learning by altering the balance between practice and rest.

Dissociable Roles of Primary Motor and Supplementary Motor Cortex in Shaping the Neural Drive to Muscle

This study uses TMS to inhibit M1 and SMA in healthy participants, revealing distinct roles in motor output: M1 controls force magnitude via firing rates, while SMA affects motor strategy through coherence and unit composition.

Connectivity between supplementary motor complex and primary motor cortex: a dual-coil paired-pulse TMS study

This study uses dual-coil paired-pulse TMS to show a spatially specific facilitatory connection between the supplementary motor complex and primary motor cortex in humans.

Impaired Sensory Gating During Standing Balance in Parkinson's Disease

This study shows that individuals with Parkinson's disease have impaired sensory gating during standing balance, as evidenced by elevated somatosensory-evoked potential amplitudes, despite comparable postural sway to healthy older adults.

Modulating Motor Cortex Plasticity via Cortical and Peripheral Somatosensory Stimulation

This study examines how cortical and peripheral somatosensory stimulation affects motor cortex plasticity, finding that cTBS increases corticospinal excitability longer than TENS and modulates M1-S1 interaction.

Changes in Motor Unit Activity of Co-activated Muscles During Dynamic Force Field Adaptation

The paper examines changes in motor unit activity during motor adaptation in dynamic environments, finding that reduced co-contraction is driven by increased agonist MU amplitude rather than firing rate changes.

Spinal Cord Ultrasound Stimulation Modulates Corticospinal Excitability

This study investigates how spinal cord ultrasound stimulation affects corticospinal excitability using varying acoustic parameters and finds that high intensity and high PRF reduce motor-evoked potential amplitudes.

Generalization in motor learning: learning bimanual coordination with one hand

This study investigates how bimanual coordination is learned and generalized through unimanual practice, showing that visual feedback is critical for transferring skills to bimanual tasks.
