Cardiac activity impacts cortical motor excitability. [PDF]

open access: yesPLoS Biology, 2023
Human cognition and action can be influenced by internal bodily processes such as heartbeats. For instance, somatosensory perception is impaired both during the systolic phase of the cardiac cycle and when heartbeats evoke stronger cortical responses ...

An index to probe cortical excitability

open access: yesJournal 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,

Dopaminergic Impact on Cortical Excitability in Humans

open access: yesReviews in the Neurosciences, 2010
Dopamine is a major neuromodulatory agent of the central nervous system. The neurotransmitter has a non-linear dose-dependent effect on cortical excitability and activity, which depends on spontaneous activity, dopamine concentration, and dopaminergic sub-receptors, amongst others.

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

open access: yesFrontiers 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

Post-Movement Beta Synchrony Inhibits Cortical Excitability [PDF]

open access: yesBrain Sciences
Background/Objectives: This study investigates the relationship between movement-related beta synchrony and primary motor cortex (M1) excitability, focusing on the time-dependent inhibition of movement. Voluntary movement induces beta frequency (13–30 Hz)

Cortical excitability and multifidus activation responses to transcranial direct current stimulation in patients with chronic low back pain during remission

open access: yesScientific Reports, 2023
Evidence indicates that patients with chronic low back pain (CLBP) have lumbar multifidus muscle (LM) activation deficit which might be caused by changes in cortical excitability.

Modulation in cortical excitability disrupts information transfer in perceptual-level stimulus processing.

open access: yesNeuroImage, 2021
Despite significant interest in the neural underpinnings of behavioral variability, little light has been shed on the cortical mechanism underlying the failure to respond to perceptual-level stimuli.

Hemodynamic correlates of fluctuations in neuronal excitability: A simultaneous Paired Associative Stimulation (PAS) and functional near infra-red spectroscopy (fNIRS) study

open access: yesNeuroImage: Reports, 2022
Background: The relationship between task-related hemodynamic activity and brain excitability is poorly understood in humans as it is technically challenging to combine simultaneously non-invasive brain stimulation and neuroimaging modalities.

Cortical Excitability in Chronic Migraine [PDF]

open access: yesCurrent Pain and Headache Reports, 2011
A proportion of episodic migraine patients experiences a progressive increase in attack frequency leading to chronic migraine (CM). The most frequent external factor that leads to headache chronification is medication overuse. The neurobiological bases of headache chronification and of the vicious circle of medication overconsumption are not completely
