N-Form® Array

Plexon Inc and Modular Bionics™ Inc. have partnered to offer the N-Form®, a customizable 3D neural probe for chronic in vivo electrophysiology. The customizable N-Form® design allows for targeting large volumes of neurons across layers and columns of cortex. The high-density design and floating interface allows for long-term, chronic recordings.

The illustration below depicts the anatomy of a 4-shank N-Form® Array.
