Our neuroscientist-designed range of silicon neural probes are optimized for large-scale single unit recording combined with optogenetics in freely-behaving, head-fixed and anaesthetised animals ranging from mice to monkeys and more.

Cambridge NeuroTech Silicon Neural Probes for electrophysiology and optogenetics

Enjoy exceptional long-term in vivo stability and record from the same neurons for weeks to months, with minimally-invasive dimensions and seamless integration with our small-footprint chronic nano-Drives for combined electrophysiology + optogenetics.

We don't just provide great probes, we also make reusable, implantable ultra-small digital headstages, allowing you to create very compact and lightweight implants thereby facilitating naturalistic behaviour in the pushing your data-gathering to the limits in the smallest of animals!

Cambridge NeuroTech mini-amp-64 digital headstages for electrophysiology in mice and rats

Benefiting from superior signal to noise performance along with minimal sensitivity to photoelectric artefacts, our silicon neural probes enable highly quality single unit and local field potential data in a wide range of experimental preparations spanning in vitro brain organoids to freely-behaving primates.

Record ACROSS and ALONG multiple cell layers

We offer a diverse variety of probes spanning from 150 - 3150 microns, with a range of probe geometries (check out our catalog for more details) and in each case, electrodes are arranged in poly-electrode grids to ensure high-resolution single unit recording and superior spike-sorting power.

Our innovative 128-channel probes offer a wide range of probe geometries to suit a variety of brain targets and are available as single- or double-sided variants, where extra recording density is desired, typically offering up to ~50% increase in single unit yield (see Science paper here).

Cambridge-NeuroTech-Advanced-Silicon-Neural-Probes-for-electrophysiology-and-optogenetics

We ONLY make SMALL probes... using our advanced manufacturing technology we can keep overall probe dimensions to a minimum (<80 microns shank-width for 64 channels) ensuring our silicon neural probes are minimally-invasive without sacrificing recording resolution and thus open up new horizons for high-resolution single unit recording and current-source-density analysis across and along cell layers.

PROBE OPTIONS

Choose from bespoke 3-D probe stacking to create your dream-probe, along with breakout-wires for LFP, EEG / EMG recording and enjoy dura-penetrating probes with our sharpened probe tips; moreover, you'll also notice much less tissue drag as you descend to target too.

PLUG-N-PLAY

We offer a variety of options for using our silicon neural probes in acute or chronic experiments and we are plug & play with all of the mainstream headstage pre-amplifier and data-acquisition solutions on the market.

BENEFITS AND ADVANTAGES

Why you should use our next-generation silicon neural probe technology...

Our silicon neural probes offer exceptional performance for both acute and chronic experiments, encompassing:

Superior chronic stability - unrivalled in vivo longevity - record the neurons you want across many days to weeks in freely behaving animals.

Optogenetics-safe - the only silicon neural probes on the market with minimized sensitivity to photo-electric artefacts making them the optimal choice for single unit recording + optogenetics.
Best-in-class signal to noise ratio - stabilized microelectrodes with typical 50 kOhm impedance; ~2x - 10x better than the competition!
Microdrive compatible - designed to fit our chronic nano-Drives with guaranteed alignment with drive-axis and convenient co-alignment with optrodes and fluidic cannulae.
Ultra-thin, robust and with sharpened-tips for dura-penetration - 15 micron thin silicon neural probes with minimal footprint yet still able to withstand considerable stress without breaking; super sharp tips capable of penetrating rodent dura.
Long-term reusable - acute probes and optrodes offering multiple re-uses across many months.
