Effects of Short-Term Dexamethasone Administration on Corticospinal Excitability [PDF]
Medicine & Science in Sports & Exercise, 2014 The short-term administration of glucocorticoids increases maximal voluntary force in healthy humans, but the underlying mechanisms remain poorly understood. The present study investigated the glucocorticoid effects on spinal and corticospinal pathways and on electromechanical properties of the tibialis anterior muscle in response to nerve stimulation ...

Fokus auf der Untersuchung des Einflusses biometrischer Faktoren auf das Ergebnis der nTMS Messung sprachrelevanter Areale neurochirurgischer Patienten [PDF]
, 2019 Objective: Navigated transcranial magnetic stimulation (nTMS) is a non-invasive mapping tool to locate functional areas of the brain, gaining importance as a preoperative diagnostic device. This is a summary of three studies, Schwarzer et al., Rosenstock

Changing ideas about others' intentions: updating prior expectations tunes activity in the human motor system [PDF]
, 2016 Predicting intentions from observing another agent’s behaviours is often thought to depend on motor resonance – i.e., the motor system’s response to a perceived movement by the activation of its stored motor counterpart, but observers might also rely on ...

Sex Differences in Mechanisms of Recovery after Isometric and Dynamic Fatiguing Tasks [PDF]
, 2018 Purpose The purpose of this study was to determine whether supraspinal mechanisms contribute to the sex difference in fatigability during and recovery from a dynamic and isometric fatiguing task with the knee extensors.

Experimental Physiology, EarlyView.Abstract Cross‐education describes the training of one limb that leads to performance enhancements in the contralateral untrained limb, driven by neural changes rather than muscle adaptation. In this systematic review and meta‐analysis, we aimed to evaluate the efficacy of cross‐education (vs. a control group) via resistance exercise training (RET) for

Suppression of Corticospinal Excitability During Negative Motor Imagery
Journal of Neurophysiology, 2003 To investigate the effect of negative motor imagery on corticospinal excitability, we performed transcranial magnetic stimulation (TMS) studies in seven healthy subjects during imagination of suppressing movements. Subjects were asked to imagine suppression of TMS-induced twitching movement of their nondominant left hands by attempting to increase the

Task-dependent Modulation of Cortical Excitability and Balance Control in Individuals with Post-concussion Syndrome [PDF]
, 2017 In most cases, symptoms resolve between 7-10 days post-concussion. However, in 10-15% of the concussed population, symptoms can remain unresolved for months to years following the head injury.

The effect of electrical stimulation on corticospinal excitability is dependent on application duration: a same subject pre-post test design [PDF]
, 2013 Background: In humans, corticospinal excitability is known to increase following motor electrical stimulation (ES) designed to mimic a voluntary contraction.

Intramuscular pathways of maladaptation in overtraining syndrome
The Journal of Physiology, EarlyView.Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...
