The Vector Array™ is optimized for large animal deep brain applications, utilizing NeuroNexus silicon microelectrode technology with added length and strength. Choose the Vector Array™ for repeated acute use or chronic implantation recording in targets multiple centimeters deep in tissue.
The Vector Array™ combines a high-resolution silicon probe with a rigid stainless steel support body. This arrangement provides strength where needed while minimizing tissue damage at the recording sites.
World class performance – Attain the excellent signal quality and minimal insertion profile of our premium silicon neural probe in a longer, more versatile form factor for deep brain applications.
Compatible with existing workflows – Industry-standard dimensions and connector options allow the vector to be swapped into your existing experimental paradigm with minimal effort or added expense.
Reach deep targets – Available in implantable lengths up to 110 mm, enabling precise targeting of deep brain structures in large animal models.
Durable and reusable – With proper care and handling , a Vector Array can be reused in 50+ times without compromise in performance.
Optogenetics compatible – Optional optical fiber integration offers straightforward and simple compatability with your preferred optogenetics solution.
Microfluidic drug delivery capablity – Electrophysiology recording before, during and after drug/fluid delivery.
Adaptability – Choose from laminar or polytrode site layouts or design your own custom Vector Array to meet specific research needs.
Chronic options – Flex-cable versions available for chronic implantation.
Smart investment for high-density NHP research – Vector delivers uncompromising performance with exceptional cost efficiency (leading value per channel in the NHP probe market!)
Expanded channel count – Record and/or stimulate from up to 128 channels in acute or chronic experiments while maintaining the same precise electrode geometry and contact density trusted across NeuroNexus arrays.
Acute Vector ArraysTM
The Acute Vector ArrayTM is optimized for acute deep brain applications, utilizing NeuroNexus microelectrode technology to record and stimulate high resolution in hard-to-reach structures.
Chronic Vector ArraysTM
The Chronic Vector ArrayTM enables access to deep brain structures (> 10 mm deep) during chronic applications. Request VC-series connector packages.
Chronic Vector ArraysTM can be configured with implantable lengths from 30 – 55 mm. Please factor in implantation hardware (clamps, etc.) when configuring your probe.
Opto Vector ArraysTM
Acute Vector Array™ can be configured with a 50µm- or 105µm-core optical fiber on the silicon shank. Request OV-series connector packages.
