Transcranial random noise stimulation and heart rate variability

Neuroscience Applied, 2023
Transcranial random noise stimulation (tRNS) is a transcranial electric stimulation (tES) method, in which an electrical current alternates randomly between two stimulation electrodes in direction and amplitude, within a given range [1]. High frequency alteration of the current has been shown to induce increase or decrease in sustained levels of ...

Noise in the brain: Transcranial random noise stimulation and perceptual noise act on a stochastic resonance‐like mechanism

European Journal of Neuroscience, 2023
Abstract Stochastic resonance (SR) is a phenomenon in which a certain amount of random noise added to a weak subthreshold stimulus can enhance signal detectability. It is unknown how external noise interacts with neural noise in producing an SR‐like phenomenon and whether this interaction results in a modulation of either network ...

Modifying response times in the Simon task with transcranial random noise stimulation [PDF]

Scientific Reports, 2017
AbstractPerceptual decisions pervade our every-day lives, and can align or conflict with inbuilt biases. We investigated these conflicting biases by applying transcranial random noise stimulation (tRNS) while subjects took part in a visual Simon task - a paradigm where irrelevant spatial cues influence the response times of subjects to relevant colour ...

Combining functional magnetic resonance imaging with transcranial electrical stimulation

Frontiers in Human Neuroscience, 2013
Transcranial electrical stimulation (tES) is a neuromodulatory method with promising potential for basic research and as a therapeutic tool. The most explored type of tES is transcranial direct current stimulation (tDCS), but also transcranial ...

Increasing Human Brain Excitability by Transcranial High- Frequency Random Noise Stimulation [PDF]

NeuroImage, 2008
For >20 years, noninvasive transcranial stimulation techniques like repetitive transcranial magnetic stimulation (rTMS) and direct current stimulation (tDCS) have been used to induce neuroplastic-like effects in the human cortex, leading to the activity-dependent modification of synaptic transmission.

Cerebellar transcranial current stimulation – An intraindividual comparison of different techniques

Frontiers in Neuroscience, 2022
Transcranial current stimulation (tCS) techniques have been shown to induce cortical plasticity. As an important relay in the motor system, the cerebellum is an interesting target for plasticity induction using tCS, aiming to modulate its excitability ...

Transcranial Random Noise Stimulation Does Not Enhance the Effects of Working Memory Training [PDF]

Journal of Cognitive Neuroscience, 2016
Abstract Transcranial random noise stimulation (tRNS), a noninvasive brain stimulation technique, enhances the generalization and sustainability of gains following mathematical training. Here it is combined for the first time with working memory training in a double-blind randomized controlled trial.

Comparison of the Effects of Transcranial Random Noise Stimulation and Transcranial Direct Current Stimulation on Motor Cortical Excitability

The Journal of ECT, 2015
The objective of this study was to examine the effect of transcranial random noise stimulation (tRNS) with and without a direct current (DC) offset on motor cortical excitability and compare results to transcranial DC stimulation (tDCS).Fifteen healthy participants were tested in a within-subjects design.

Transcranial direct current stimulation (tDCS) for upper limb rehabilitation after stroke: future directions.

Journal of NeuroEngineering and Rehabilitation, 2018
Transcranial Direct Current Stimulation (tDCS) is a potentially useful tool to improve upper limb rehabilitation outcomes after stroke, although its effects in this regard have shown to be limited so far.

Top-down and bottom-up stimulation techniques combined with action observation treatment in stroke rehabilitation: a perspective

Frontiers in Neurology, 2023
Stroke is a central nervous system disease that causes structural lesions and functional impairments of the brain, resulting in varying types, and degrees of dysfunction.
