Standard Probes

MR-Compatible Probes


When packaged with the MR-Series Package, NeuroNexus neural probes include only trace amounts of ferromagnetic material and cause minimal or no distortion during typical MR imaging. In addition to the packages listed here, most of our Omnetics connector-based packages can be made MR compatible. Please contact us for details. (Above image courtesy of Dr. David Leopold, NIMH)


Penetrating Electrodes Probe Package Acute

MR-Series offers Probe Packages that are exact duplicates of the non-MR versions. All materials used in these Probe Packages include minimal ferromagnetic material. We currently offer 6 MR variants of popular Probe Packages. More Probe Packages can be made MR-compatible, contact us for more information.


A common challenge associated with MR experiments is how to interface with a non-MR compatible headstage. This will cause MR noise during the functional MR experiment. Headstage amplifiers should be placed away from the implant to avoid distortion. A variety of cable assemblies and adaptors developed for previous projects are available. Contact us for additional customized adaptor/cable solutions for your setup.
