Monitoring cortical excitability during repetitive transcranial magnetic stimulation in children with ADHD: a single-blind, sham-controlled TMS-EEG study

, 2012
Background: Repetitive transcranial magnetic stimulation (rTMS) allows non-invasive stimulation of the human brain. However, no suitable marker has yet been established to monitor the immediate rTMS effects on cortical areas in children.

Investigating cortical excitability and inhibition in patients with schizophrenia: A TMS-EEG study. [PDF]

Transcranial magnetic stimulation (TMS) combined with electromyography (EMG) has widely been used as a non-invasive brain stimulation tool to assess excitation/inhibition (E/I) balance.

Transcranial Magnetic Stimulation as a Tool to Investigate Motor Cortex Excitability in Sport

Brain Sciences, 2021
Transcranial magnetic stimulation, since its introduction in 1985, has brought important innovations to the study of cortical excitability as it is a non-invasive method and, therefore, can be used both in healthy and sick subjects.

The Effects of Nicotine on Cortical Excitability After Exercise

, 2020
The use of smokeless tobacco/nicotine products is common among athletes, but clear evidence for their positive or negative effect on sports performance is lacking.

An index to probe cortical excitability

Journal of Neural Engineering
Abstract Objective. Cortical excitability can be defined as the cortex’s responsiveness to incoming stimuli. It can be probed with brain stimulation, either globally and non-invasively, using transcranial magnetic stimulation or locally through direct electrical stimulation of the cortex. Here,

Cortical excitability in migraine [PDF]

The Journal of Headache and Pain, 2000
Cortical hyperexcitability in migraine has been suggested to play a pivotal role in triggering migraine attacks, possibly via generation of spreading depression. Low levels of plasma, intracellular and brain magnesium as well as increased amplitudes of visual evoked potentials support this theory. More recent data on evoked and even related potentials,

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Cortical Excitability after Mild Traumatic Brain Injury in Children

, 2015
Introduction: Mild traumatic brain injury is frequently complicated by post-concussive syndrome. It is unknown why these symptoms persist, but recent research suggests that cortical excitability may play a role.

Neurophysiological Mechanisms Underlying Cortical Hyper-Excitability in Amyotrophic Lateral Sclerosis: A Review

Brain Sciences, 2021
Amyotrophic lateral sclerosis (ALS) is a progressive neuromotor disease characterized by the loss of upper and lower motor neurons (MNs), resulting in muscle paralysis and death. Early cortical hyper-excitability is a common pathological process observed

Efficacy of Intermittent Theta‐Burst Stimulation for Prolonged Disorders of Consciousness: A Prospective, Randomized, Controlled Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness
