Corticospinal excitability is modulated by temporal feedback gaps

NeuroReport, 2018
The integration of sensorimotor information is important for accurate goal-directed movement and affects corticospinal excitability (CE). This study investigated CE during the motor preparation period in a goal-directed movement task with temporal feedback gaps.

Acute high-intensity and moderate-intensity interval exercise do not change corticospinal excitability in low fit, young adults.

PLoS ONE, 2020
Previous research has demonstrated a lack of neuroplasticity induced by acute exercise in low fit individuals, but the influence of exercise intensity is unclear.

Selective modulation of NaV channel gating counteracts aberrant hyperexcitability and rescues motor function and survival in a model of spinal muscular atrophy

British Journal of Pharmacology, EarlyView.
Background and Purpose Spinal muscular atrophy (SMA) is a motor neuron disease caused by SMN1 gene loss, leading to reduced survival motor neuron (SMN) protein and progressive motor neuron degeneration. Although SMN‐restoring therapies improve outcomes, residual disease burden and non‐curative efficacy underscore the need for complementary treatments ...

Haptic Adaptive Feedback to Promote Motor Learning With a Robotic Ankle Exoskeleton Integrated With a Video Game

Frontiers in Bioengineering and Biotechnology, 2020
Background: Robotic devices have been used to rehabilitate walking function after stroke. Although results suggest that post-stroke patients benefit from this non-conventional therapy, there is no agreement on the optimal robot-assisted approaches to ...

Motor Sequence Learning Under Sleep Deprivation

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep deprivation (SD) compromises declarative memory encoding and subsequent consolidation, yet its consequences for the acquisition of new motor skill learning remain unknown. Forty‐eight healthy adults underwent either one night of total SD or normal sleep and were tested the next morning using a multimodal approach combining psychomotor ...

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 ...

Arm posture-dependent changes in corticospinal excitability are largely spinal in origin [PDF]

, 2016
Biceps brachii motor evoked potentials (MEPs) from cortical stimulation are influenced by arm posture. We used subcortical stimulation of corticospinal axons to determine whether this postural effect is spinal in origin. While seated at rest, 12 subjects

Intermittent low‐intensity contractions cause a dissociation between maximal motor unit firing rates and changes in torque and contractile speed

Experimental Physiology, EarlyView.
Abstract The purpose was to test: (1) whether the decline in maximal motor unit (MU) firing rate is an invariable response when maximal voluntary contraction (MVC) torque is reduced following a submaximal muscle fatiguing task; and (2) whether fatigue‐induced slowing of contractile speed and firing rate decline are co‐dependent. Ten participants (three

Age and asymmetry of corticospinal excitability, but not cardiorespiratory fitness, predict cognitive impairments in multiple sclerosis

IBRO Neuroscience Reports, 2023
Background: Cognitive impairment is a disabling and underestimated consequence of multiple sclerosis (MS), with multiple determinants that are poorly understood.

Feedback from group III/IV afferents in skeletal muscle slows heart rate acceleration when transitioning from rest to low‐intensity exercise in males

Experimental Physiology, EarlyView.
Abstract Group III/IV skeletal muscle afferents respond to intramuscular mechanical and metabolic stimuli and are more active in fatigued muscle. These afferents project onto the brainstem and motor cortex and modulate cardiovascular and motor responses during exercise.
