The DC-STIMULATOR MR is an fMRI-compatible stimulator for use in scientific research. It is not approved for use in therapy.
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.
FeaturesTechnical 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)
