Cognitive and emotional effects of bilateral prefrontal anodal tDCS and high-frequency tRNS in schizophrenia: a randomized sham-controlled study [PDF]
SchizophreniaCognitive deficits in schizophrenia significantly hinder functional outcomes and often remain unresponsive to conventional treatments. While initial evidence suggested potential pro-cognitive effects of electrical brain stimulation in schizophrenia ...

Reduction of cognitive fatigue and improved performance at a VR-based driving simulator using tRNS [PDF]
iScienceSummary: Cognitive fatigue (CF) increases accident risk reducing performance, especially during complex tasks such as driving. We evaluated whether transcranial random noise stimulation (tRNS) could mitigate CF and improve driving performance.

tRNS boosts visual perceptual learning in participants with bilateral macular degeneration [PDF]
Frontiers in Aging NeurosciencePerceptual learning (PL) has shown promise in enhancing residual visual functions in patients with age-related macular degeneration (MD), however it requires prolonged training and evidence of generalization to untrained visual functions is limited ...

A tRNS investigation of the sensory representation of time [PDF]
Scientific Reports, 2018 The understanding of the mechanisms underlying the representation of temporal intervals in the range of milliseconds/seconds remains a complex issue. Different brain areas have been identified as critical in temporal processing.

Enhancing visual perception by modulating prestimulus alpha and beta power with tRNS [PDF]
Communications BiologyVisual variability is linked to prestimulus alpha (8–13 Hz) and beta (13–30 Hz) power fluctuations, yet their causal role remains unclear. Using transcranial random noise stimulation (tRNS), we tested whether externally modulating cortical excitability ...

High-frequency TRNS reduces BOLD activity during visuomotor learning. [PDF]
PLoS ONE, 2013 Transcranial direct current stimulation (tDCS) and transcranial random noise stimulation (tRNS) consist in the application of electrical current of small intensity through the scalp, able to modulate perceptual and motor learning, probably by changing ...

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. hf-tRNS induces random neural activity in the system that

Excitatory and inhibitory lateral interactions effects on contrast detection are modulated by tRNS [PDF]
Scientific Reports, 2019 Contrast sensitivity for a Gabor signal is affected by collinear high-contrast Gabor flankers. The flankers reduce (inhibitory effect) or increase (facilitatory effect) sensitivity, at short (2λ) and intermediate (6λ) target-to-flanker separation ...

Occipital and parietal non-invasive brain stimulation enhances perceptual learning and transfer: evidence from high-frequency tRNS [PDF]
Frontiers in NeurosciencePerceptual training yields specific, long-lasting improvements, yet its transfer to untrained conditions is often limited. This tension has been proposed to involve interactions between early sensory plasticity and higher-order parietal processes, with ...
