TDCS transcranial electrical stimulator

The DC-STIMULATOR PLUS is a stimulator for use in scientific research that provides stimulation with weak currents, either direct or alternating, (transcranial Electrical Stimulation tES), within non-invasive Interventional Neurophysiology. The electrical charge and current density applied through a constant current source are far below the threshold for releasing a stimulus. Depending on the duration, the used current, the current density, and the frequency of the stimulation has a modular effect on existing neuronal elements by either activating or inhibiting cortical activity. Features The DC-STIMULATOR PLUS is a micro-processor-controlled constant current source. It meets the highest safety standards thanks to (hardware- and software-based) multistage monitoring of the current path. By continuously monitoring electrode impedance it can detect insufficient contact with the skin and automatically terminate stimulation. This is a reliable method of excluding any injury to the patient. Besides transcranial direct current stimulation (tDCS) the DC-STIMULATOR PLUS also makes it possible to conduct bi-polar stimulation (tACS). 1 channel stimulation tDCS – transcranial direct current stimulation bipolar stimulation with tACS (transcranial alternating current stimulation) and tRNS (transcranial random noise stimulation) adjustable range of current ±4,500 µA, maximum adjustable current strength ±1,500 µA (peak-to-peak) adjustable application time up to 30 minutes frequencies adjustable up to 250 Hz, phase freely adjustable 4 standard modes – tDCS (continuous stimulation) – pulse (cyclical stimulation
