Transcranial direct current stimulation (tDCS) devices apply direct current through electrodes on the scalp with the intention to modulate brain function for experimental or clinical purposes. All tDCS devices include a current controlled stimulator, electrodes that include a disposable electrolyte, and headgear to position the electrodes on the scalp. Transcranial direct current stimulation dose can be defined by the size and position of electrodes and the duration and intensity of current… 

Noninvasive Electrical Brain Stimulation of the Central Nervous System

The evidence for tES use across varied clinical applications, spanning treatment of neuropsychiatric disorders and neurorehabilitation following injury, as well as a tool to change cognition and behavior in healthy individuals is developing.

A Computational Analysis of the Electric Field Components in Transcranial Direct Current Stimulation

A general trend is confirmed in the distribution of tangential and normal E-fields on gyri and sulci areas, respectively, partially independent of electrode configuration, for various electrode montages commonly used in clinical applications.

A Computational Parcellated Brain Model for Electric Field Analysis in Transcranial Direct Current Stimulation

This chapter offers a summary of recent works which have studied the effect of simulated EF magnitude and orientation in tDCS, as well as providing new results derived from an anatomically representative parcellated brain model based on finite element method (FEM).

Transcranial Direct Current Stimulation Enhances Exercise Performance: A Mini Review of the Underlying Mechanisms

The main focus of the Effects of tDCS on EP section is to provide a brief description of the effects of the phenomena on maximal and submaximal types of exercise, and the Mechanisms Behind the Effects and mechanisms behind the effects are described.

Adaptive current tDCS up to 4 mA

Electroencephalographic analysis of brain activity after interventions with transcranial direct current stimulation over the motor cortex: a systematic review

There is inconsistency in the processes and procedures used for the acquisition of brain signals, even when limiting the search to clinical trials offering an analysis of evaluations performed before and after clinical interventions.

Therapeutic Use of Transcranial Direct Current Stimulation in the Rehabilitation of Prolonged Disorders of Consciousness

It is argued that neuroimaging and electrophysiological assessments may serve as more sensitive biomarkers to identify changes after tDCS that are not yet apparent behaviorally, and given the evidence that concurrent brain stimulation and physical therapy can enhance motor rehabilitation, future studies should focus on the integration of tDCS with conventional rehabilitation programmes from the subacute phase of care onwards.

Modulation of solute diffusivity in brain tissue as a novel mechanism of transcranial direct current stimulation (tDCS)

Modulation of solute diffusivity and ECS could explain diverse outcomes of tDCS and suggest novel therapeutic strategies, according to the breadth of brain disorders and functions responsive to transcranial direct current stimulation.



Spatial and polarity precision of concentric high-definition transcranial direct current stimulation (HD-tDCS)

Using a range of concentric HD-tDCS montages, it is shown that cortical region of influence can be controlled while balancing other design factors such as intensity at the target and uni-directionality, which can provide categorical improvements in targeting compared to conventional tDCS.

Optimized multi-electrode stimulation increases focality and intensity at target

If a target location and stimulation orientation can be defined by the clinician, then the proposed technique is superior in terms of both focality and intensity as compared to previous solutions and is thus expected to translate into improved patient safety and increased clinical efficacy.

Electrode Positioning and Montage in Transcranial Direct Current Stimulation

Different alternatives for electrode placement for tDCS clinical trials on pain are shown, discussing advantages and disadvantages of each method of stimulation.

Shaping the effects of transcranial direct current stimulation of the human motor cortex.

Increased focality of tDCS might improve the interpretation of the functional effects of stimulation because it will restrict its effects to more clearly defined cortical areas, and such paradigms may help to achieve more selective tDCS effects.

Technique and Considerations in the Use of 4x1 Ring High-definition Transcranial Direct Current Stimulation (HD-tDCS)

The purpose of this article is to systematically describe 4x1 HD-tDCS use for M1 stimulation, as well as the considerations to be taken for safe and effective stimulation.

Safety parameter considerations of anodal transcranial Direct Current Stimulation in rats

Comparison of cephalic and extracephalic montages for Transcranial Direct Current Stimulation - A numerical study

Modeling of conventional and alternative electrode montages via the Finite Element Method (FEM) has been utilized to provide insight into tDCS montage performance, and accurate simulations using a high definition, anatomically correct female human model based on the Visible Human Project dataset have given evidence that extracephalic cathode locations provide deeper stimulation of the primary motor cortex than the traditional cephalIC electrode montage.
