Cyberkinetics, Case to develop system to help restore extremity function

n experiments using monkeys. Together, the team has the potential to advance cortical interfaces into the world of restorative rehabilitation as a "brain-body interface" (BBI).

About the BrainGateTM System
The BrainGate Neural Interface System is a proprietary brain-computer interface (BCI). BrainGate is an investigational device currently in pilot clinical trials that consists of an internal sensor to detect brain cell activity and external processors that convert these brain signals into a computer-mediated output under the person's own control. The sensor is a tiny silicon chip about the size of a baby aspirin with one hundred electrodes, each thinner than a human hair, that can detect the electrical activity of neurons. The sensor is implanted on the surface of the area of the brain responsible for movement, the motor cortex. A small wire connects the sensor to a pedestal that is placed on the skull, extending through the scalp. An external cable connects the pedestal to a cart containing computers, signal processors and monitors that enable the study operators to determine how well study participants can control devices driven by their neural output ? that is, by thought alone. The ultimate goal of the BrainGate System development program is to create a safe, effective and unobtrusive universal operating system that will enable those with motor impairments resulting from a variety of causes to quickly and reliably control a wide range of devices, including computers, assistive technologies and medical devices, and in this implementation (project) the muscles of a person with paralysis, simply by using their thoughts.

Cyberkinetics is currently conducting two pilot clinical trials of the BrainGateTM System. In its first pilot clinical trial currently underway, clinical researchers are testing the safety and feasibility of the BrainGate in those with severe paralysis resulting from spinal cord injury (SCI), muscu
