Standard Probes: Silicon multichannel microelectrode arrays

Standard Probes

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 multichannel microelectrodes 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 microelectrode arrays for single-unit, multi-unit, and local field potential (LFP) recording and stimulation. To help researchers target different structures in the brain, Standard probes can be configured with a vast collection of microelectrode array 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)
  • Site layout

Array Designs

To start configuring a probe, find a microelectrode array that meets your needs, or contact us for help. Once you have selected a microelectrode array design, match it to a package so it can interface with your headstage.
