OBELISK is a needle-form, depth neural probe designed for minimally-invasive precise intracerebral recording and stimulation.
The details
Pick from our standard set (cross-section 50 um x 5 um) or ask for custom design.
Standard design starts at 5'000$, custom designs at 25'000$.
OBELISK is a needle-form depth neural probe intended for intracerebral recording and stimulation in research experiments. The probe provides 16 longitudinally distributed channels, enabling simultaneous access to neural activity and stimulation sites along a single insertion trajectory. Both recording and stimulation are supported in monopolar and bipolar configurations.
Electrodes are coated with proprietary stimulation-grade surface coatings to achieve high charge injection capacity and low impedance, supporting repeatable stimulation within established electrochemical safety limits and stable recording performance across channels.
Insertion is performed using a dedicated mechanical shuttle, supplied with the probe, which provides temporary stiffness during implantation and enables accurate targeting of deep brain structures. After insertion, the shuttle is withdrawn, leaving only the flexible probe in place. Thin film implants such as OBELISK reduce foreign body reaction after implantation by matching the brain's mechanical stiffness. The shuttle-based approach improves insertion reliability while minimizing probe cross-section and tissue disruption during chronic or acute experiments.
OBELISK is compatible with standard stereotaxic workflows and interfaces with commonly used neural acquisition and stimulation systems via standardized connectors or using our own headstage. The probe is suitable for studies involving depth recordings, circuit mapping, causal perturbation, and preclinical neuromodulation research where controlled access to deep brain regions is required.
Not for human use.
