Transcranial Direct Current Stimulator E2000

Ⅰ. Introduction

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that applies a specific, low-intensity electrical current (usually 1-2 mA) to specific brain areas through electrodes placed on the skull, which can modulate neural activity in the cerebral cortex.

YINGCHI tCS-E2000 can be used for both scientific research and clinical treatment. It is safe, efficient, non-invasive, easy-to-use and of low cost, which can even store treatment records. This electrical stimulator is equipped with wireless Bluetooth technology, allowing users to operate 32 electrical stimulators at the same time, and each electrical stimulator can perform any treatment protocol.

3. tDCS combined with neuroimaging

tDCS combined with EEG:
· The "offline" approach, with EEG recordings following tDCS stimulation to assess short- and long-term aftereffects of tDCS induction;
· The "online" approach, with EEG recordings during tDCS stimulation, to assess the ongoing changes that occur during tDCS stimulation.

tDCS combined with fNIRS:
· Affordable, non-invasive, and portable;
· Optical and does not interfere with the current of tDCS;
fNIRS has been applied to various studies, including studies of cortical plasticity and resting-state functional connectivity;
· Although fNIRS is limited to cortical imaging at moderate spatial resolution, it has the potential to provide high activation-related signal detection sensitivity and high temporal resolution.
· fNIRS is able to detect event-related optical signals that occur within a few hundred milliseconds and correlate with evoked potentials measured by synchronized electroencephalography (EEG), much faster than fMRI’s second resolution.

tDCS combined with fMRI:
· Research on montage selection: functional imaging helps montage selection locate the brain regions that stimulates target functional activation;
· Predictive studies: Baseline fMRI can provide baseline measures of neural network activation and inform later interpretation of behavioral/neural responses to tDCS (i.e. "baseline fMRI can serve as a predictor");
· Mechanism research: Use functional magnetic resonance imaging to study brain changes under the effect of tDCS, and ultimately determine where, when and how stimulation affects brain function and related behaviors.
