TDCS transcranial electrical stimulator DC-STIMULATOR MR

tACStRNS

The DC-STIMULATOR MR is an fMRI-compatible stimulator for use in scientific research. It is an extension of our single-channel DC-STIMULATOR PLUS, so it benefits from multi-stage monitoring and a complete range of tES modes of operation: transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS). The DC-STIMULATOR MR allows the application of transcranial electrical stimulation (tES) during functional magnetic resonance imaging (fMRI) to localize the exact position of cortical activation. Features Technical features of the DC-STIMULATOR MR include 1 channel, unipolar (DC) and bipolar (AC) 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 - single (continuous stimulation) - pulse (cyclical stimulation activation/deactivation) - sinus (sinus wave) - noise (normally distributed) Use during fMRI, no interference of the MRI images during EPI sequence RF filter module with MRI-compatible cables and electrodes Customer-specific programs possible (optional) "Study mode" for blind processing of genuine and 'pseudo' stimulation (optional) External trigger input and output (optional)
