DC-STIMULATOR MR - Stimulator for neuroscientific research

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 complete range of tES modes of operation: transcranial direct current simulation (tDCS), transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS).

The DC-STIMULATOR MR allows to apply transcranial electrical stimulation (tES) during functional magnetic resonance imaging (fMRI) to localize the exact position of cortical activation.

DC-STIMULATOR MR features

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)
