R-Net MR

R-Net MR: Sponge-based electrode system for simultaneous EEG-fMRI

The addition of the R-Net MR to our MRI product portfolio provides the flexibility to choose the right electrode system for your research needs. The R-Net MR consists of saltwater sponges and passive Ag/AgCl electrodes housed in a durable and flexible silicone structure. The MR version of the R-Net also has current-limiting resistors for safe recordings in the MRI environment and a gel-based ECG electrode. The R-Net MR is available for BrainAmp MR amplifiers and can be used in scanners up to 3 T. Its use is subject to our general 3 T EEG-fMRI safety guidelines.

Highest safety standards

• • All electrodes in the R-Net MR are fitted with serial current-limiting resistors.
  • Resistors are also placed inside the cap connector, acting like an additional RF-filter.
  • ECG electrodes contain higher resistors than EEG electrodes and the lead wire is made of carbon to compensate for the technical characteristics of longer wires.
  • The drop-down ECG electrode lead wire is sheathed in plastic to avoid direct contact with the skin of the participant.
  • All electrode lead wires are routed on the outside of the net and secured to avoid loops and cable movement.
  • Wire length from electrode to the amplifier input is fixed to the minimal required length.
  • Cable tree exit point options are available to fit with different MRI head coils.
  • Clear MR labelling and safety guidelines are in line with industry standards.

Ease of use

• • Ultra-fast measurement preparation with our potassium chloride electrolyte solution
  • Highly convenient – no gel residues
  • The only sponge-based electrode system available that follows the international 10-10 positioning system
  • Serial number sticker on connector box for easy tracking and layout questions
