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.
