Transcranial electric stimulation such as transcranial random noise stimulation (tRNS) and transcranial direct current stimulation (tDCS) have been used to investigate structure-function relationships in numerical cognition. Recently, tRNS was suggested to be more effective than tDCS. However, so far there is no evidence on the differential impact of tDCS and tRNS on numerical cognition using t...

PURPOSE: Transcranial Direct Current Stimulation (tDCS) is a neuromodulation technique. Hypothesized to affect cortical excitability, tDCS has been found to facilitate clinical treatments (e.g., stroke, depression, pain relief) and enhance cognition (e.g., math, verbal working memory). A typical tDCS setup involves placing electrodes over the scalp and driving a constant, low (~1mA) electric cu...

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 brain excitability. We investigated the effects of these transcranial electrical stimulation techniques in the early and later stages of visuomot...

Acquisition of fine motor skills is a time-consuming process as it based on learning via frequent repetitions. Transcranial electrical stimulation (tES) promising means enhancing simple skill development neuromodulatory mechanisms. Here, we report that non-invasive neurostimulation facilitates the complex bimanual associated with surgical task. During training 12 medical students Fundamentals L...

Transcranial direct current stimulation (tDCS) is a safe method to modulate cortical excitability. Anodal stimulation can improve the stimulated area's functions whereas cathodal stimulation reduces them. Currently, a lot of clinical trials have been conducted to study the effect of tDCS on post-stroke motor and language deficits, in depression, chronic pain, memory impairment and tinnitus in o...

Citation: Hanley CJ (2016) Commentary: Systematic assessment of duration and intensity of anodal transcranial direct current stimulation on primary motor cortex excitability. As a pertinent addition to the literature, the study highlights several concerns currently facing those in the transcranial electrical stimulation (tES) community. Tremblay et al. (2016) investigated modulations of cortico...

Pathologic tilt of subjective visual vertical (SVV) frequently has adverse functional consequences for patients with stroke and vestibular disorders. Repetitive transcranial magnetic stimulation (rTMS) of the supramarginal gyrus can produce a transitory tilt on SVV in healthy subjects. However, the effect of transcranial direct current stimulation (tDCS) on SVV has never been systematically stu...

Transcranial direct current stimulation (tDCS) is the application of a weak electrical direct current (1.5 mA), which has the ability to modulate spontaneous firing rates of the cortical neurons by depolarizing or hyperpolarizing the neural resting membrane potential. tDCS in patients with depressive disorders has been proven to be an interesting therapeutic method potentially influencing patho...

Transcranial direct current stimulation (tDCS) modulates cortical excitability and is being used for human studies more frequently. Here we probe the underlying neuronal mechanisms by measuring polarity-specific changes in neurotransmitter concentrations using magnetic resonance spectroscopy (MRS). MRS provides evidence that excitatory (anodal) tDCS causes locally reduced GABA while inhibitory ...

Introduction: Working memory plays a critical role in cognitive processes which are central to our daily life. Neuroimaging studies have shown that one of the most important areas corresponding to the working memory is the dorsolateral prefrontal cortex (DLFPC). This study was aimed to assess whether bilateral modulation of the DLPFC using a noninvasive brain stimulation, namely transcranial di...
