Advanced Platform Technology Center
Neural Interfaces
APT Center research and development projects are related to new ways of interfacing with the central nervous system will focus primarily on methods of extracting signals from the cortex for controlling assistive devices or detecting and diagnosing dysfunctional cortical activity, as well as microsystems designed to promote cortical rewiring and facilitate adaptive neural plasticity. In the peripheral nervous system, we will continue to optimize the design of high density flat nerve interface electrodes (FINEs) for selectively activating the human femoral and sciatic nerves in motor system neuroprostheses for standing and walking, as well as the sensory nerves of the brachial plexus to provide natural sensory feedback to upper extremity amputees.
From the Dynamic Intracortical Probes project: (a) Four-contact NC probe next to a penny, as a size reference. The large rectangular contact pads are at the top of the device, and the electrode contacts are near the tip of the narrow shank. (b) Close-up view of the shank of a two-contact NC probe, with the gold traces and electrode contacts visible.
