Standard Probes

Product Code: 53

NeuroNexus Standard Probes are fabricated using state-of-the-art silicon MEMS technology, initially developed at the University of Michigan. NeuroNexus has refined the technology to produce smaller and more versatile devices with precise and highly reproducible mechanical, geometric, and electrical characteristics. As a result, NeuroNexus users can expect consistent recording results every time they use our probes.

NeuroNexus offers a wide variety of silicon electrode arrays for single-unit, multi-unit, and local field potential (LFP) recording and stimulation. To help researchers target different structures in the brain, Standard electrodes come in a vast collection of designs, each with different parameters, including: length (to span cortical layers), number of shanks (to span cortical columns), electrode site area (to target individual or groups of neurons), electrode site spacing (to target specific areas), and site layout.


To start configuring a probe, turn to the Electrode Array Design section on page 87 to find an electrode array that meets your needs, or contact us directly. Once you have selected an electrode array design, match it to a connector package so it can interface with your headstage.
