Electrode Packages
Connector and cable assemblies that complete a probe for your preparation and headstage.
An assembled probe is a silicon probe plus a package: the connector, cable and housing between the probe and the headstage. Select the package based on the experimental preparation (acute, chronic, freely moving) and plug-in compatibility with your headstage.
Find the right package
Select by experimental preparation, by series, or by the connector your headstage uses.

01.
Probe
The silicon probe design: site count, shank count and site pitch. Select by geometry in the design space.
Open the design space02.
Package
The connector, cable and housing attached to the probe. Its connector sets which headstages are compatible.
03.
Headstage
Plugs into the package connector and amplifies or digitizes the signal. Compatible headstages are listed on each package datasheet.
See headstages04.
Data acquisition system
The hardware the headstage connects to: SmartBox, XDAQ or a compatible third-party system. It streams the recording to the acquisition software.
See systems05.
Acquisition — Radiens Allego
Instrument control, recording and live monitoring of every channel, with PSTHs during acquisition. Allego runs with every NeuroNexus system.
See Radiens06.
Analysis and curation — Radiens Videre
File-based analysis and visualization after the recording: spike sorting, LFP analysis and curation, with quality and provenance recorded on every file and NWB read and write.
See RadiensConnector families

What is a probe package?
A probe package is the connector assembly, with a cable where the series uses one, that is built onto the silicon electrode array so the probe can be connected and implanted. The package is selected based on the experimental preparation (acute, chronic or freely moving) and plug-in compatibility with the headstage.
How do I choose a package for my headstage?
Select the package based on plug-in compatibility with your headstage. Connectors by series: Omnetics on most Hybrid, CM, Vector, Fusion, Matrix and DBS packages; Hirose on ZIF packages, which mate with TDT Zif-Clip headstages; Molex X3 or Panasonic on X-Series packages; Samtec on most A-Series packages and on SiNAPS packages; µHDMI or Omnetics 12 on Activus packages; CQ4 on Q-Trode packages. The Compatibility section of each package datasheet lists the compatible headstages.
Which package for a chronic mouse implant?
CM and Hybrid packages are used for chronic implants in mice. CM packages are cableless, with the connector on the assembly, from 0.16 g. Hybrid packages use a flexible polyimide cable between the probe and the connector, from 0.14 g. Select Hybrid when the connector must sit away from the probe shank.
Can I change a probe's package later?
No. The package is built onto the probe at assembly, and a probe in a different package is a different product. Select the package based on the experimental preparation and plug-in compatibility with your headstage, and order spares in the same package.
What do the series letters mean (A, H, Z, CM, X)?
A (A-Series): a rigid printed-circuit interconnect for acute and intra-operative recording. H (Hybrid): a flexible polyimide cable between probe and connector, for chronic implants. Z (ZIF): zero-insertion-force connectors that mate with TDT Zif-Clip headstages. CM: a cableless package for chronic implants. X (X-Series): the smallest-footprint packages, which mate directly with X-Series headstages. Each package series has a glossary entry.
Are MRI-conditional packages a separate order?
Yes. MRI-conditional packages carry the MR prefix (for example MRH, MRHC, MRCM and MRA) and use non-magnetic connectors. An MRI-conditional package is selected at order; a standard package cannot be converted to an MRI-conditional one.
How much does the package add to head weight?
Measured package weights range from 0.14 g (Hybrid) to 4.6 g (A-Series). Where a package weight has been measured, it is listed on the package datasheet.
Not sure which package?
A NeuroNexus scientist can recommend a package for your probe, headstage and preparation.
