Tuning the brakes – Modulatory role of transcranial random noise stimulation on inhibition

Brain Stimulation, 2023
AbstractBackgroundEveryday decision-making requires the ability to flexibly modify and sometimes terminate our actions, such as avoiding a tempting slice of cake to hitting the brakes in an emergency. Neural oscillations, such as beta-band rhythms observed over the medial prefrontal cortex(mPFC), help regulate these context-dependent behaviours ...

The Effect of Transcranial Random Noise Stimulation on Cognitive Training Outcome in Healthy Aging. [PDF]

Front Neurol, 2021
Background and Objective: Aging is associated with a decline in attentional and executive abilities, which are linked to physiological, structural, and functional brain changes. A variety of novel non-invasive brain stimulation methods have been probed in terms of their neuroenhancement efficacy in the last decade; one that holds significant promise is

The effect of emotion intensity on time perception: a study with transcranial random noise stimulation. [PDF]

Exp Brain Res, 2023
AbstractEmotional facial expressions provide cues for social interactions and emotional events can distort our sense of time. The present study investigates the effect of facial emotional stimuli of anger and sadness on time perception. Moreover, to investigate the causal role of the orbitofrontal cortex (OFC) in emotional recognition, we employed ...

Altering brain dynamics with transcranial random noise stimulation. [PDF]

Sci Rep, 2019
AbstractRandom noise can enhance the detectability of weak signals in nonlinear systems, a phenomenon known as stochastic resonance (SR). This concept is not only applicable to single threshold systems but can also be applied to dynamical systems with multiple attractor states, such as observed during the phenomenon of binocular rivalry.

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 ...

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

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.

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 ...

Transcranial Random Noise Stimulation Acutely Lowers the Response Threshold of Human Motor Circuits. [PDF]

J Neurosci, 2021
Transcranial random noise stimulation (tRNS) over cortical areas has been shown to acutely improve performance in sensory detection tasks. One explanation for this behavioral effect is stochastic resonance (SR), a mechanism that explains how signal processing in nonlinear systems can benefit from added noise.

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

NeuroImage, 2009
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.
