BrainGate – Control The World Through Your Brain


Okay, I want you to imagine something. What if you just thought that you want to lift your arm and grab the glass of water which is on the table in front of you? AND like “wish granted”, it just happens! Wouldn’t it be just amazing?

Well, a group of erudite researchers from the Brown University have something for you here. These experts have launched the very first human use of a high-width wireless brain-computer interference (BCI) with a human. The application enables people afflicted with tetraplegia to type on a computer and manipulate their robotic prostheses just by thinking in their brains.

The structure of BCI compromises transmitting brain signals at single-neuron and in broadband fidelity by physically knotting the user to the decoding system. The cables are substituted by a small transmitter about 2 inches in its dimension and weighing about over 1.5 ounces. The unit of the system sits on the top of the user’s head and connects to an electrode array within the brain’s motor cortex through the same port previously used by the wired system.

Recently an experiment was conducted on two paralyzed patients, the two patients used the BCI wireless transmitter to click, point and type efficiently on a tablet computer.

Wireless BCI

Physically wiring these systems limits their production levels. It reduces the researcher’s ability to test them for a long time and in different settings. But now, the Brown University has demonstrated that a wireless BCI can record brain signals at the same rate as a wired device for up to 24 hours in a patient’s home. Simeral said, “Miscellaneous companies have entered the BCI field, and some have implanted low-bandwidth wireless systems. We are thrilled to have a high-bandwidth wireless system that advances in the scientific and clinical capabilities for future systems”.

According to the researchers of BCI, the study of the system represents an indispensable step toward a major initiative that aids to restore the independence of those people who are unable to move independently. Studies have been conducted on wireless devices with lower bandwidth which can deftly transmit full spectrum of signals recorded by an intracortical sensor.

“We’ve represented the wireless systems that is equivalent to the wired system that have been gold standard in BCI performance for last few years”. Study leader, John Simeral from Brown University. The only difference between a wireless and wired system is that people are not supposed to tether physically by the decoding system.
