CMOS-based flexible-arrange distributed neural interface system for wide-area BMI

We propose and demonstrate distributed CMOS-based neural interface system with flexible placement. The target application of the device is BMI covering wide area of animal brain. It consists of small-sized, probe-shaped neural interface devices and wiring network based on coaxial cables. The significant feature of the system is that placement of the multiple probe-shaped devices can be determined in the surgical operation on the applicant animal. It gives a large advantage in flexibility and usability for various types of animal BMI experiments.
