Improving working memory: Exploring the effect of transcranial random noise stimulation and transcranial direct current stimulation on the dorsolateral prefrontal cortex

Clinical Neurophysiology, 2011
The aim of this study was to determine if working memory (WM) performance is significantly improved after the delivery of transcranial random noise stimulation (tRNS) to the left dorsolateral prefrontal cortex (DLPFC), compared to an active comparator or sham.Ten participants undertook three experimental sessions in which they received 10 min of anodal

Modulatory mechanisms underlying high-frequency transcranial random noise stimulation (hf-tRNS): A combined stochastic resonance and equivalent noise approach [PDF]

Brain Stimulation, 2019
Background: High-frequency transcranial random noise stimulation (hf-tRNS) is a neuromodulatory technique consisting of the application of alternating current at random intensities and frequencies.

Perceptual learning can be improved by transcranial random noise stimulation

, 2012
Perceptual learning is considered a manifestation of neural plasticity in the human brain. We investigated brain plasticity mechanisms in a visual perceptual learning task using non-invasive transcranial electrical stimulation (tES, i.e., direct current stimulation tDCS and random noise stimulation tRNS) applied on the visual areas.

The effects of high-frequency transcranial random noise stimulation (hf-tRNS) on global motion processing: An equivalent noise approach

Brain Stimulation, 2018
Background: High frequency transcranial random noise stimulation (hf-tRNS) facilitates performance in several perceptual and cognitive tasks, however, little is known about the underlying modulatory mechanisms.

Effects of transcranial random noise stimulation timing on corticospinal excitability and motor function

Behavioural Brain Research, 2021
Although transcranial random noise stimulation (tRNS) to the primary motor cortex (M1) increases corticospinal excitability and improves motor function, the effects of tRNS timing have not been clarified when combined with motor training. The purpose of this study was to clarify the effects of different tRNS timing on corticospinal excitability and ...

Basic Mechanisms of Transcranial Alternating Current and Random Noise Stimulation

2021
Through neuromodulation of neural activity, transcranial alternating current stimulation (tACS) interacts with neural oscillations in a frequency- and phase-specific manner, thereby influencing human brain function. Currents are applied at the scalp with intensities up to 4 mA peak to peak (except for electroconvulsive therapy with much higher ...

Modulation of the dichotic right ear advantage during bilateral but not unilateral transcranial random noise stimulation

Brain and Cognition, 2018
Transcranial electrical stimulation (tES) has been increasingly adopted to modulate perceptual and cognitive functions, but the effects on auditory perception are still relatively uncharted.

P 209. Transcranial random noise stimulation: A new approach to stimulating the brain

Clinical Neurophysiology, 2013
Introduction Transcranial random noise stimulation (tRNS) is a neuromodulatory technique that involves the delivery of a bi-directional, randomly oscillating current. Introduction of a positive DC offset to the stimulation can produce a polarity-specific randomly oscillating current that produces effects similar to that of transcranial direct current ...
