Instantaneous voltage as an alternative to power- and phase-based interpretation of oscillatory brain activity

NeuroImage, 2017
For decades, oscillatory brain activity has been characterized primarily by measurements of power and phase. While many studies have linked those measurements to cortical excitability, their relationship to each other and to the physiological ...

Relationship Between Cortical Excitability Changes and Cortical Thickness in Subcortical Chronic Stroke

Frontiers in Neurology, 2022
Ischemic stroke leads to excitability changes of the motor network as probed by means of transcranial magnetic stimulation (TMS). There is still limited data that shows to what extent structural alterations of the motor network might be linked to ...

Different Current Intensities of Anodal Transcranial Direct Current Stimulation Do Not Differentially Modulate Motor Cortex Plasticity

Neural Plasticity, 2013
Transcranial direct current stimulation (tDCS) is a noninvasive technique that modulates the excitability of neurons within the motor cortex (M1). Although the aftereffects of anodal tDCS on modulating cortical excitability have been described, there is ...

Saccadic performance and cortical excitability as trait-markers and state-markers in rapid-cycling bipolar disorder: a 2-case follow-up study.

Frontiers in Psychiatry, 2013
Background: The understanding of physiopathology and cognitive impairments in mood disorders requires finding objective markers. Mood disorders have often been linked to hypometabolism in the prefrontal dorsolateral cortex, and to GABAergic and ...

Primary sensory and motor cortex excitability are co-modulated in response to peripheral electrical nerve stimulation. [PDF]

PLoS ONE, 2012
Peripheral electrical stimulation (PES) is a common clinical technique known to induce changes in corticomotor excitability; PES applied to induce a tetanic motor contraction increases, and PES at sub-motor threshold (sensory) intensities decreases ...

Effects of Cang-Ai volatile oil on depressed mood and cortical excitability in human

Pharmacological Research - Modern Chinese Medicine, 2023
Background: Cang-Ai Volatile Oil (CAVO) is a traditional Chinese medicine prescription that can be used for improving depressive symptoms through the regulation of dopamine (DA) and 5-hydroxytryptamine (5-HT) and inhibition of the inflammation.

Early brainstem [18F]THK5351 uptake is linked to cortical hyperexcitability in healthy aging

JCI Insight, 2021
BACKGROUND Neuronal hyperexcitability characterizes the early stages of Alzheimer’s disease (AD). In animals, early misfolded tau and amyloid-β (Aβ) protein accumulation — both central to AD neuropathology — promote cortical excitability and neuronal ...

Cortical excitability in human somatosensory and visual cortex: implications for plasticity and learning – a minireview

Frontiers in Human Neuroscience, 2023
The balance of excitation and inhibition plays a key role in plasticity and learning. A frequently used, reliable approach to assess intracortical inhibition relies on measuring paired-pulse behavior.

Bring the pain: wounding reveals a transition from cortical excitability to epithelial excitability in Xenopus embryos

Frontiers in Cell and Developmental Biology
The cell cortex plays many critical roles, including interpreting and responding to internal and external signals. One behavior which supports a cell’s ability to respond to both internal and externally-derived signaling is cortical excitability, wherein

Transcranial Magnetic Stimulation for the treatment of tinnitus: Effects on cortical excitability

BMC Neuroscience, 2007
Background Low frequency repetitive transcranial magnetic stimulation (rTMS) has been proposed as an innovative treatment for chronic tinnitus. The aim of the present study was to elucidate the underlying mechanism and to evaluate the relationship ...
