The benchmark for multichannel, high-density neural recording

The Utah Array has become the industry benchmark for recording large populations of neurons. Over the past two decades, this patented microelectrode array technology has undergone numerous refinements and repeated validations in a variety of species including humans, monkeys, birds, rodents, felines and fish—both in-vitro and in-vivo.

These extensive efforts have delivered proven, well-documented methods to obtain stable and long-term neural recordings of action potentials (spikes) and local field potentials in brain and peripheral-nerve tissue. Because the array can be wired to various connector types, researchers can choose a connector that is optimal for chronic or acute recordings—from small to large subjects as well as from slice and cell culture preparations.

Pneumatic inserter
Electrode array insertion system for the Utah array.

The Blackrock pneumatically actuated inserter implants microelectrode arrays into brain, spinal cord and peripheral-nerve tissue. Its high-speed, momentum-impulse insertion mechanism facilitates complete array implantation with minimal tissue damage. Adjustable insertion speed and implantation depth allows researchers to optimize device settings for different electrode configurations and tissue preparations.

Key features

  • High-speed pneumatic insertion
  • Adjustable implantation depth
  • Minimal tissue insult
  • In-vivo or in-vitro preparations
  • Sterilizable
