Dopaminergic Impact on Cortical Excitability in Humans

Reviews 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]

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

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

Scientific 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.

NeuroImage, 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.

Passive and active markers of cortical excitability in epilepsy. [PDF]

, 2023
EEG has been the primary diagnostic tool in clinical epilepsy for nearly a century. Its review is performed using qualitative clinical methods that have changed little over time.

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

NeuroImage: 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]

Current 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

Methodological approach for assessing motor cortical excitability changes with single-pulse transcranial magnetic stimulation

MethodsX, 2023
Transcranial Magnetic Stimulation (TMS) serves as a crucial tool in evaluating motor cortex excitability by applying short magnetic pulses to the skull, inducing neuron depolarization in the cerebral cortex through electromagnetic induction.

Cell cycle and developmental control of cortical excitability in Xenopus laevis [PDF]

, 2022
Interest in cortical excitability – the ability of the cell cortex to generate traveling waves of protein activity – has grown considerably over the past twenty years. Attributing biological functions to cortical excitability requires an understanding of

Causal decoding of individual cortical excitability states

NeuroImage, 2021
Brain responsiveness to stimulation fluctuates with rapidly shifting cortical excitability state, as reflected by oscillations in the electroencephalogram (EEG).
