Task-dependent alteration of beta-band intermuscular coherence is associated with ipsilateral corticospinal tract excitability

Frontiers in Sports and Active Living, 2023
Beta-band (15–30 Hz) synchronization between the EMG signals of active limb muscles can serve as a non-invasive assay of corticospinal tract integrity.

Effects of motor preparation and spatial attention on corticospinal excitability in a delayed-response paradigm [PDF]

, 2007
The preparation of motor responses during the delay period of an instructed delay task is associated with sustained neural firing in the primate premotor cortex.

Interlimb neural interactions in the corticospinal pathways

Journal of Physical Fitness and Sports Medicine, 2014
Corticospinal excitability is known to be modulated during voluntary muscle contraction of distal limbs. Although a large number of studies have demonstrated the variety of modulations in corticospinal excitability during distal limb movement, those ...

Motor simulation without motor expertise: enhanced corticospinal excitability in visually experienced dance spectators [PDF]

, 2012
The human “mirror-system” is suggested to play a crucial role in action observation and execution, and is characterized by activity in the premotor and parietal cortices during the passive observation of movements.

Effect of levetiracetam on human corticospinal excitability

Neurology, 2001
To investigate whether levetiracetam (LTC) alters corticospinal excitability in humans.Although the antiepileptic activity of LTC is well recognized, its mechanism of action has yet to be determined. Transcranial magnetic stimulation (TMS) has been used to investigate the pharmacologic effects of various antiepileptic drugs on human corticospinal ...

Preconditioning of low-frequency repetitive transcranial magnetic stimulation with transcranial direct current stimulation: evidence for homeostatic plasticity in the human motor cortex [PDF]

, 2004
Recent experimental work in animals has emphasized the importance of homeostatic plasticity as a means of stabilizing the properties of neuronal circuits. Here, we report a phenomenon that indicates a homeostatic pattern of cortical plasticity in healthy

Early Right Motor Cortex Response to Happy and Fearful Facial Expressions: A TMS Motor-Evoked Potential Study

Brain Sciences, 2021
The ability to rapidly process others’ emotional signals is crucial for adaptive social interactions. However, to date it is still unclear how observing emotional facial expressions affects the reactivity of the human motor cortex. To provide insights on

Repeatability of corticospinal and spinal measures during lengthening and shortening contractions in the human tibialis anterior muscle [PDF]

, 2012
Elements of the human central nervous system (CNS) constantly oscillate. In addition, there are also methodological factors and changes in muscle mechanics during dynamic muscle contractions that threaten the stability and consistency of transcranial ...

The effect of rolling massage on the excitability of the corticospinal pathway [PDF]

Applied Physiology, Nutrition, and Metabolism, 2018
The aim of the present study was to investigate the alterations of corticospinal excitability (motor evoked potential, MEP) and inhibition (silent period, SP) following rolling massage of the quadriceps muscles. Transcranial magnetic and femoral nerve electrical stimuli were used to elicit MEPs and compound muscle action potential (Mmax) in the vastus

Sustained Isometric Wrist Flexion and Extension Maximal Voluntary Contractions on Corticospinal Excitability to Forearm Muscles during Low-Intensity Hand-Gripping

Brain Sciences, 2020
The wrist extensors demonstrate an earlier fatigue onset than the wrist flexors. However, it is currently unclear whether fatigue induces unique changes in muscle activity or corticospinal excitability between these muscle groups.
