The BrainGate Company is a privately-held firm focused on the creation of technology that will allow severely disabled individuals, including those with traumatic spinal cord injury and loss of limbs, to communicate and control common everyday functions by thought alone.

The BrainGate neural interface system consists of a sensor to monitor brain signals together with computer software and hardware, which turns brain signals into digital commands for external devices. This is a type of brain-computer interface intended to put robotics and other assistive technology under the brain’s control. The size of a baby aspirin, the sensor contains 100 hair-thin electrodes that can record the activity of small groups of brain cells. It is implanted into the motor cortex, a part of the brain that directs movement.
