Silicon Neural Probes
Silicon and polymer neural probes — 210+ validated designs, fabricated, assembled, and characterized in-house.
Target Structures
Cerebral Cortex
Single-shank linear arrays (16–64 sites) and multi-shank configurations (2–8 shanks) for laminar and volumetric recording. Includes Buzsaki-optimized designs for hippocampal work.
Thalamus & Deep Nuclei
Thin-film flexible grids for cortical surface recording — ECoG, micro-ECoG, and custom surface electrode configurations.
Hippocampus, Midbrain, and Brainstem
Flexible cable assemblies and form factors designed for long-term implantation. Chronic-ready versions of most probe geometries with pre-attached connectors.
Spinal Cord & Autonomic Ganglia
3D volumetric electrode matrices for simultaneous sampling across cortical columns and deep structures. Up to 384 channels in a single device.
Nerves
MEMS-fabricated active pixel probes with up to 1,024 recording channels per device. Ultra-high-density recording for large-scale neural population studies.
Heart
Work directly with our engineering team to develop probe geometries optimized for your specific application, target structure, and experimental requirements.
Cerebral Cortex
Hybrid silicon and stainless steel microelectrodes for large-scale neural recording in primates and deep brain structures. Up to 128 channels with electrode access depths exceeding 100 mm — reaching targets that conventional silicon probes cannot.Vector Arrays combine the site density and spatial precision of silicon probes with the mechanical robustness required for chronic large-animal implantation.
Up to 128 Channels
High-density laminar recording across cortical layers and deep nuclei.
110+ mm Depth Access
Reach deep brain targets in primates and large animals.
Chronic Implantable
Designed for long-term recording in freely moving animals.

Fusion Probes
Double-sided silicon probes with 360° electrode coverage and integrated optical waveguides for simultaneous optogenetic stimulation and electrical recording. Available in 32, 64, and 128 channel configurations.Fusion probes eliminate the need for separate optical fibers and recording electrodes — reducing surgical complexity and improving spatial co-registration between stimulation and recording sites.
360° Electrode Coverage
Double-sided site placement captures activity from all directions around the shank.
Integrated Optogenetics
Built-in optical waveguides for precise light delivery at recording sites.
Acute & Chronic
Available in both acute reusable and chronic implantable form factors.
Finding the Right Probe

Request ConsultationEvery NeuroNexus probe is fabricated, assembled, and electrically characterized in our own facility — the same facility where the Michigan probe was first manufactured. No third-party fabrication. Full traceability from wafer to packaged device. Acute probes are validated for 50+ reuses.
Your probe determines which headstage and DAQ you need. Every NeuroNexus probe includes a headstage compatibility specification — connector type, channel count, and impedance range are matched at the design stage. Need help building the recording chain? Start with your probe and we'll recommend the rest.
Better Data Starts at the Electrode
Radiens knows your probe — its geometry, channel map, and expected electrical characteristics. When you record with a NeuroNexus probe through Radiens, you get real-time signal quality assessment tuned to the specific device in your experiment.That's the advantage of vertical integration: the company that fabricated the electrode also wrote the software that evaluates its performance.
