Motor neural prostheses, also termed Brain Machine Interfaces (BMIs), have the potential to help restore motor functionality for patients suffering from a wide range of neurological injuries and disorders. These systems convert the electrical activity measured from neurons into control signals, which can then be used to guide assistive technologies, such as prosthetic arms. A variety of designs have been attempted for these systems, but they share the basic form shown in Figure 1. The electrical activity of neurons can be acquired from a variety of electrodes. These signals are acquired using custom electronics. Neural “decoder” algorithms are then applied to neural activity to estimate movement commands. These commands can be used to attempt a wide variety of tasks, and performance can be measured with a number of common metrics.
