Movement is accomplished by the controlled activation of motor unit populations. Our
understanding of motor unit physiology has been derived from experimental work on the …

Movements are generated by the coordinated activation of motor units. Recent technological
advances have made it possible to identify the concurrent activity of several tens of motor …

Previous studies have shown that synchronized beta frequency (14-30 Hz) oscillations in the
primary motor cortex are involved in maintaining steady contractions of contralateral arm …

This paper examines the physiological mechanisms responsible for differences in the
amplitude of force fluctuations between young and old adults. Because muscle force is a …

Synchronization of neural activity is considered essential for information processing in the
nervous system. Both local and inter-regional synchronization are omnipresent in different …

Oscillations of the motor cortex interact with similar activity of the spinal motoneuron pool in
the 15–30Hertz frequency range. Recent observations have demonstrated how this …

Recordings from primary motor cortex (M1) during periods of steady contraction show
oscillatory activity; these oscillations are coherent with the activity of contralateral muscles …

In motor neuron disease, the focus of therapy is to prevent or slow neuronal degeneration
with neuroprotective pharmacological agents; early diagnosis and treatment are thus …

We have previously demonstrated an increase in the excitability of the leg motor cortical
area in relation to acquisition of a visuo‐motor task in healthy humans. It remains unknown …

This study examined the strength of motor unit synchronisation based on time‐and
frequency‐domain measures during postural, shortening and lengthening contractions of a …
