neuroConn DC-STIMULATORs cover all requirements for transcranial stimulation.

DC-STIMULATOR MR

The DC-STIMULATOR MR is a stimulator for conducting non-invasive transcranial direct- and alternating current stimulation (tDCS, tACS) on people specifically during magnetic resonance imaging (f)MRI.

The DC-STIMULATOR MR 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.

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)
