Biocompatible multichannel electrodes for long-term neurophysiological studies and clinical therapy--novel concepts and design.

Chronic neural interfaces that are both structurally and functionally stable inside the brain over long time periods and that have minimal effects on the physiological conditions of the neural tissue to be studied hold great promise to become invaluable research and clinical tool in the near future. In this chapter, I will briefly review the state of the art of neural interfaces and the concepts behind our recent research and development of ultrathin multichannel electrodes.
