Paralyzed Man Uses Thoughts Alone to Control Robot Arm, Touch Friend's Hand, After Seven Years
With brain-computer interface (BCI) technology, the thoughts of Tim Hemmes, who sustained a spinal cord injury that left him unable to move his body below the shoulders, were interpreted by computer algorithms and translated into intended movement of a computer cursor and, later, a robot arm, explained lead investigator Wei Wang, Ph.D., assistant professor, Department of Physical Medicine and Rehabilitation, Pitt School of Medicine.

"When Tim reached out to high-five me with the robotic arm, we knew this technology had the potential to help people who cannot move their own arms achieve greater independence," said Dr. Wang, reflecting on a memorable scene from September 2011 that was re-told in stories around the world. "It's very important that we continue this effort to fulfill the promise we saw that day."

Six weeks before the implantation surgery, the team conducted functional magnetic resonance imaging (fMRI) of Mr. Hemmes' brain while he watched videos of arm movement. They used that information to place a postage stamp-size electrocortigraphy (ECoG) grid of 28 recording electrodes on the surface of the brain region that fMRI showed controlled right arm and hand movement. Wires from the device were tunneled under the skin of his neck to emerge from his chest where they could be connected to computer cables as necessary.

For 12 days at his home and nine days in the research lab, Mr. Hemmes began the testing protocol by watching a virtual arm move, which triggered neural signals that were sensed by the electrodes. Distinct signal patterns for particular observed movements were used to guide the up and down motion of a ball on a computer screen. Soon after mastering movement of the ball in two dimensions, namely up/down and right/left, he was able to also move it in/out with accuracy on a 3-dimensional display.

To all you damn fools. BCI tech has been around much longer than any of you idiots were even born. THAT'S RIGHT!

Also the reason this shit is so primitive is because no one gives two shits about what they are doing here other than those who need it or know someone who need it.

The truth, the real BCI tech was made ages ago and is far superior than anything around today. It was made long ago from backward engineering the symbiotic tech of real out of this world origins.

We are currently around 50 years set back today from what our secret technology is capable of.

Since these guys can't backward engineer, they are going to take a lot longer in progression with this technology. It will remain primitive for years to come, this is for certain.
