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 ...

The effects of transcranial random noise stimulation on motor function: A comprehensive review of the literature

Physiology & Behavior, 2023
The present review considers all papers published on the topic up to the end of the year 2022. Transcranial random noise stimulation (tRNS) is a non-invasive neuromodulation technique introduced about 15 years ago whose use is becoming increasingly widespread in neuroscience.

The effect of transcranial random noise stimulation on corticospinal excitability and motor performance

Neuroscience Letters, 2019
Although transcranial random noise stimulation (tRNS) over the primary motor cortex (M1) region can be used to enhance cortical excitability, it remains unclear whether tRNS over the M1 region improves motor performance. The present study aims to clarify the effect of tRNS on both corticospinal excitability and motor performance. We applied tRNS at the

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 ...

Bifrontal high-frequency transcranial random noise stimulation is not effective as an add-on treatment in depression

Journal of Psychiatric Research, 2021
Depressive disorders are linked to dysfunction in prefrontal cortical areas. Hence, non-invasive neurostimulation of the prefrontal cortex has demonstrated antidepressant efficacy. In the present study, we investigated the efficacy of high frequency transcranial random noise stimulation (hf-tRNS) as an add-on treatment for depression in a sham ...

P197 Electroencephalographic effects of transcranial random noise stimulation of the temporal cortex

Clinical Neurophysiology, 2017
Question Transcranial random noise stimulation (tRNS) is an innovative technique of non-invasive electrical stimulation with a handful of publications most of them investigating processes of the motor system. With respect to the auditory system only. Limited evidence is available for modulation of auditory processing in healthy controls and patients ...

EP 134. Effect of transcranial random noise stimulation depends on sensitivity to sham stimulation

Clinical Neurophysiology, 2016
Introduction Tranccranial random noise stimulation (tRNS) induces a consistent excitability increase lasting at least 60 min after 10 min of stimulation, as demonstrated by both physiological measures and behavioural Tasks ( Terney et al., 2008 ).

Modulating Subjective Time Perception with Transcranial Random Noise Stimulation (tRNS)

Journal of Cognitive Enhancement, 2019
Understanding the neural and cognitive mechanisms underlying time estimation remains a challenge. Transcranial electric stimulations, such as transcranial random noise stimulation (tRNS), are useful tools to interfere with brain activity and identifying brain areas involved in temporal processing.

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

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.
