Force steadiness: from motor units to voluntary actions
Voluntary actions are controlled by the synaptic inputs that are shared by pools of spinal
motor neurons. The slow common oscillations in the discharge times of motor units due to …

Blind identification of the spinal cord output in humans with high-density electrode arrays implanted in muscles
Invasive electromyography opened a new window to explore motoneuron behavior in vivo.
However, the technique is limited by the small fraction of active motoneurons that can be …

Muscles from the same muscle group do not necessarily share common drive: evidence from the human triceps surae
It has been proposed that movements are produced through groups of muscles, or motor
modules, activated by common neural commands. However, the neural origin of motor …

Beta band oscillations in motor cortex reflect neural population signals that delay movement onset
P Khanna, JM Carmena - elife, 2017 - elifesciences.org
Motor cortical beta oscillations have been reported for decades, yet their behavioral
correlates remain unresolved. Some studies link beta oscillations to changes in underlying …

Reading and modulating cortical β bursts from motor unit spiking activity
M Bräcklein, DY Barsakcioglu… - Journal of …, 2022 - Soc Neuroscience
β Oscillations (13–30 Hz) are ubiquitous in the human motor nervous system. Yet, their
origins and roles are unknown. Traditionally, β activity has been treated as a stationary …

Only the fastest corticospinal fibers contribute to β corticomuscular coherence
Human corticospinal transmission is commonly studied using brain stimulation. However,
this approach is biased to activity in the fastest conducting axons. It is unclear whether …

Decrease in force steadiness with aging is associated with increased power of the common but not independent input to motor neurons
AM Castronovo, N Mrachacz-Kersting… - Journal of …, 2018 - journals.physiology.org
Declines in motor function with advancing age have been attributed to changes occurring at
all levels of the neuromuscular system. However, the impact of aging on the control of …
