Functional network dynamics in photosensitive epilepsy depend on stimulation frequency and photoparoxysmal electroencephalographic response

Epilepsia, EarlyView.
Abstract Objective Photosensitive epilepsy (PSE) is a reflex epilepsy, where abnormal electroencephalographic (EEG) responses are induced by photic stimulation. Photosensitivity is classified into four types based on the propagation of the brain's response to visual stimuli.

Restoring the encoding properties of a stochastic neuron model by an exogenous noise [PDF]

, 2015
Here we evaluate the possibility of improving the encoding properties of an impaired neuronal system by superimposing an exogenous noise to an external electric stimulation signal. The approach is based on the use of mathematical neuron models consisting

Distinct impacts of sodium channel blockers on the strength–duration properties of human motor cortex neurons

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to determine how voltage‐gated sodium channel (VGSC) blockers modulate cortical excitability in vivo. VGSCs are critical for regulating axonal excitability, yet the effects of sodium channel‐blocking medications on human cortical neurons remain poorly characterized.

The role of stimulus-driven versus goal-directed processes in fight and flight tendencies measured with motor evoked potentials induced by Transcranial Magnetic Stimulation [PDF]

, 2019
This study examines two contrasting explanations for early tendencies to fight and flee. According to a stimulus-driven explanation, goal-incompatible stimuli that are easy/difficult to control lead to the tendency to fight/flee.

Evidence for increased background neural noise in migraine with aura: Hyperactive but not hyperresponsive

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study had two aims: (1) to investigate the contrast gain in migraine and compare it to that in photosensitive epilepsy; (2) to explore any effects of colored spectacles (precision ophthalmic tints [POT]) on contrast gain. Background Individuals with migraine with aura (MA) typically show high amplitude electrophysiological ...

Comparative study of motor cortical excitability changes following anodal tDCS or high‐frequency tRNS in relation to stimulation duration

Physiological Reports, 2020
Background In this study, we investigate the capacity of two different non‐invasive brain stimulation (NIBS) techniques (anodal transcranial direct current stimulation (anodal tDCS) and high‐frequency transcranial random noise stimulation (hf‐tRNS ...

Personalized Brain-Computer Interface Models for Motor Rehabilitation

, 2017
We propose to fuse two currently separate research lines on novel therapies for stroke rehabilitation: brain-computer interface (BCI) training and transcranial electrical stimulation (TES).

Tone‐Evoked Sleep Electroencephalographic Slow Oscillations as a Function of Peripheral Rhythms: New Insights Into the Brain–Heart Integration

Journal of Sleep Research, EarlyView.
ABSTRACT Recent studies have shown that acoustic stimulation, a common neuromodulation technique, can enhance slow‐wave activity (SWA), which is associated with immune, autonomic nervous system activity and cognitive health benefits. Despite some disagreement, many studies suggest that maximising tone‐evoked SWA depends on the timing of the acoustic ...

Exploring the Prospects of Transcranial Electrical Stimulation (tES) as a Therapeutic Intervention for Post-Stroke Motor Recovery: A Narrative Review

Brain Sciences
Introduction: Stroke survivors often have motor impairments and related functional deficits. Transcranial Electrical Stimulation (tES) is a rapidly evolving field that offers a wide range of capabilities for modulating brain function, and it is safe and ...
