Assessment of Motor Evoked Potentials in Multiple Sclerosis

Sensors, 2023
Transcranial magnetic stimulation (TMS) is a noninvasive technique mainly used for the assessment of corticospinal tract integrity and excitability of the primary motor cortices. Motor evoked potentials (MEPs) play a pivotal role in TMS studies.

MRI in ALS: Corticospinal tract hyperintensity [PDF]

Neurology, 2003
A 32-year-old woman with no family history presented with 12 months of progressive left upper limb weakness. Examination revealed moderate wasting and pyramidal weakness in all muscle groups in the left upper limb, especially the shoulder girdle and …

Axonal remodeling in the corticospinal tract after stroke: how does rehabilitative training modulate it?

Neural Regeneration Research, 2017
Stroke causes long-term disability, and rehabilitative training is commonly used to improve the consecutive functional recovery. Following brain damage, surviving neurons undergo morphological alterations to reconstruct the remaining neural network.

Corticospinal interface to restore voluntary control of joint torque in a paralyzed forearm following spinal cord injury in non-human primates

Frontiers in Neuroscience, 2023
The corticospinal tract plays a major role in the control of voluntary limb movements, and its damage impedes voluntary limb control. We investigated the feasibility of closed-loop brain-controlled subdural spinal stimulation through a corticospinal ...

Maturation of Corticospinal Tracts in Children With Hemiplegic Cerebral Palsy Assessed by Diffusion Tensor Imaging and Transcranial Magnetic Stimulation

Frontiers in Human Neuroscience, 2019
Aim: To assess changes in the developmental trajectory of corticospinal tracts (CST) maturation in children with hemiplegic cerebral palsy (HCP).Methods: Neuroimaging data were obtained from 36 children with HCP for both the more affected (MA) and less ...

Transcranial Magnetic Stimulation Measures, Pyramidal Score on Expanded Disability Status Scale and Magnetic Resonance Imaging of Corticospinal Tract in Multiple Sclerosis

Bioengineering, 2023
Probing the cortic ospinal tract integrity by transcranial magnetic stimulation (TMS) could help to understand the neurophysiological correlations of multiple sclerosis (MS) symptoms. Therefore, the study objective was, first, to investigate TMS measures

Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

Electrically Evoked Compound Action Potentials in Spinal Cord Stimulation: Implications for Preclinical Research Models

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives The study aimed to assess the feasibility of recording electrically evoked compound action potentials (ECAPs) from the rat spinal cord. To achieve this, we characterized electrophysiological responses of dorsal column (DC) axons from electrical stimulation and quantified the relationship between ECAP and motor thresholds (ECAPTs and

Downregulation of UBE4B promotes CNS axon regrowth and functional recovery after stroke

iScience, 2023
Summary: The limited intrinsic regrowth capacity of corticospinal axons impedes functional recovery after cortical stroke. Although the mammalian target of rapamycin (mTOR) and p53 pathways have been identified as the key intrinsic pathways regulating ...

Chimpanzee (Pan troglodytes) precentral corticospinal system asymmetry and handedness: a diffusion magnetic resonance imaging study. [PDF]

PLoS ONE, 2010
Most humans are right handed, and most humans exhibit left-right asymmetries of the precentral corticospinal system. Recent studies indicate that chimpanzees also show a population-level right-handed bias, although it is less strong than in humans.We ...
