X-Series Probes

Our X-Series probes have been designed to offer the smallest footprint possible on the market, with unique elements of modularity to provide you with the most flexible platform for electrophysiology.


Discover the possibilities of our Xseries probes – the ultimate solution for high-quality recordings in freely behaving animals.

  • Compact – Our smallest circuit board footprint. Connect and implant with the X-Headstage for the lowest-profile option.
  • Low-cost  Roughly half the price compared to traditional Omnetics connector packages.
  • High-resolution – Compatible with highly configurable microelectrode arrays that enable single-unit isolation even in dense brain regions.
  • Simplified – Eliminate the need for adaptors or cumbersome connectors to plug/unplug for every recording.

Don’t settle for less – try our Xseries probes today and experience the difference for yourself!

Jumper Cable

Introducing the Jumper Cable, designed to bridge X3 EIB and X-Headstage. This ultra-thin polyimide cable with a 0.09mm thickness, offers flexibility through easy bending and folding. The cable can be utilized in either direction (left or right). Its pin-to-pin pinout between the two end connectors (male to female) ensures efficient and reliable connections for your applications.

X3 Cycle Extender

The throwaway adapter that is designed to extend the connectivity cycles of the X-Headstage’s onboard low-profile connector. This adapter offers pin-to-pin mapping, ensuring compatibility. By incorporating this adapter, you can increase the spacing between the EIB and the X-Headstage by an additional 1.2 mm, effectively enhancing the overall connectivity and longevity of your setup.

Headstage Adapters

NeuroNexus has developed an adapter-based solution that interfaces with the standard connectors used in commercially available electrodes such as silicon probes or microwires. This approach has enabled the X-Headstages™ to be more compact, even with the adaptors installed. Moreover, when pins do break, X-Headstages™ can be easily and cost-effectively repaired instead of being discarded.

Headstage Remapper

Remaps the X3SR32 input to the X3R32 input, utilizing the right input connector. This remapping enables the use of standard adapter accessories, streamlining compatibility and expanding the range of available options for your setup.
