Brain Gate Technology

Brain Gate is a brain implant system built and previously owned by Cyber kinetics, currently under development and in clinical trials, designed to help those who have lost control of their limbs, or other bodily functions, such as patients with amyotrophic lateral sclerosis (ALS) or spinal cord injury. The Brain gate technology and related Cyber kinetic’s assets are now owned by privately held Brain gate, LLC. The sensor, which is implanted into the brain, monitors brain activity in the patient and converts the intention of the user into computer commands

In its current form, Brain Gate consists of a sensor implanted in the brain and an external decoder device, which connects to some kind of prosthetic or other external object. The sensor uses 100 hair-thin electrodes that sense the electromagnetic signature of neurons firing in specific areas of the brain, for example, the area that controls arm movement. The sensor translates that activity into electrically charged signals, which are then sent to an external device and decoded in software. The decoder connects to and can use the brain signals to control an external device, such as a robotic arm, a computer cursor, or even a wheelchair. In essence, Brain Gate allows a person to manipulate objects in the world using only the mind.

In addition to real-time analysis of neuron patterns to relay movement, the Brain Gate array is also capable of recording electrical data for later analysis. A potential use of this feature would be for a neurologist to study seizure patterns in a patient with epilepsy.

Brain Gate was originally developed by researchers in the Department of Neuroscience at Brown University in conjunction with bio-tech company Cyber kinetics, Inc.. Cyber kinetics later spun off the device manufacturing to Black rock Micro systems, who now manufactures the sensors and the data acquisition hardware. The Brain Gate Company purchased the intellectual property and related technology from Cyber kinetics and continues to own the intellectual property related to Brain Gate.
