Neural Prosthesis Development

Previously-Completed Contracts

NIDCD no longer posts Quarterly Progress Reports (QPRs) for new contract awards. Principal Investigators may provide QPRs on their own Web sites, in addition to publishing their work in peer-reviewed manuscripts. This page lists previously-completed contracts and, when available, their QPRs. All reports are in PDF format (get Adobe Reader).
