Reducing attention bias toward negative emotional stimuli with transcranial random noise stimulation: a randomized, double-blind, sham-controlled, crossover study [PDF]

Scientific Reports
Excessive attention bias interferes with daily life and contributes to various psychiatric conditions. Previous studies have demonstrated that anodal transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex (DLPFC)

Transcranial Random Noise Stimulation-induced plasticity is NMDA-receptor independent but sodium-channel blocker and benzodiazepines sensitive

Frontiers in Neuroscience, 2015
Background: Application of transcranial random noise stimulation (tRNS) between 0.1 and 640 Hz of the primary motor cortex (M1) for 10 minutes induces a persistent excitability increase lasting for at least 60 minutes.

Impact of chronic transcranial random noise stimulation (tRNS) on GABAergic and glutamatergic activity markers in the prefrontal cortex of juvenile mice

Progress in Brain Research, 2021
Transcranial random noise stimulation (tRNS), a non-invasive neuromodulatory technique capable of altering cortical activity, has been proposed to improve the signal-to-noise ratio at the neuronal level and the sensitivity of the neurons following an inverted U-function.

Three repeated sessions of transcranial random noise stimulation (tRNS) leads to long-term effects on reaction time in the Go/No Go task [PDF]

Neurophysiologie Clinique, 2019
We aimed to investigate whether the number of sessions delivered within one day influences the acute and long-term effects of transcranial random noise stimulation (tRNS) applied over the dorsolateral prefrontal cortex (DLPFC) on inhibitory control.Thirty-six healthy participants were randomly assigned to receive either (i) 3 active (3A), (ii) 1 active

Modulating excitation/inhibition balance through transcranial electrical stimulation: physiological mechanisms in animal models [PDF]

Frontiers in Neuroscience
The balance between excitatory and inhibitory (E/I) activity is a fundamental property of neural circuits, ensuring precise information processing and preventing pathological states such as hyperexcitability or network silencing.

Effects on nonverbal numerical acuity performance after a single-session transient random noise stimulation over the intraparietal sulcus or dorsolateral prefrontal cortex [PDF]

Scientific Reports
We investigated the effects of cognitive training with transcranial random noise stimulation (tRNS) applied to the intraparietal sulcus (IPS) or dorsolateral prefrontal cortex (DLPFC) on improving a multidirectional number line estimation task.

The Effects of 1 mA tACS and tRNS on Children/Adolescents and Adults: Investigating Age and Sensitivity to Sham Stimulation [PDF]

Neural Plasticity, 2020
The aim of this study was to investigate the effect of transcranial random noise (tRNS) and transcranial alternating current (tACS) stimulation on motor cortex excitability in healthy children and adolescents. Additionally, based on our recent results on

Differential effects of high-frequency transcranial random noise stimulation (hf-tRNS) on contrast sensitivity and visual acuity when combined with a short perceptual training in adults with amblyopia

Neuropsychologia, 2018
Amblyopia is a neuro-developmental disorder characterised by several functional impairments in spatial vision even with the best optical correction. There is evidence that extensive perceptual training can improve visual acuity (VA) and contrast sensitivity (CS) in adults with amblyopia.

Potential impact of bifrontal transcranial random noise stimulation (tRNS) on the semantic Stroop effect and its resting-state EEG correlates

Neurophysiologie Clinique, 2019
The Stroop effect performance reflects cognitive resistance to interference. We aimed to investigate the effect of a single transcranial random noise stimulation session (tRNS) applied over the dorsolateral prefrontal cortex (DLPFC) on the semantic Stroop effect and its resting electroencephalography (EEG) correlates (β/α ratio).In a randomized, double-

Auditory Cortex tACS and tRNS for Tinnitus: Single versus Multiple Sessions [PDF]

Neural Plasticity, 2014
Tinnitus is the perception of a sound in the absence of an external acoustic source, which often exerts a significant impact on the quality of life.
