Wireless Device Transmits Brain Signals

Exercise Plays Vital Role Maintaining Brain HealthTechnology that allows paralyzed people to use thought commands to manipulate computers already exists. However, it is not practical for everyday use: the design is complicated and messy, involving many wires and laboratory environments. In a consortium called BrainGate, researchers from Brown University and Blackrock Microsystems invented a wireless device that can potentially bring mind-control technology out of the labs and into people’s homes.

Here’s how the technology works:

  1. A small device attaches to a person’s skull and is wired to electrodes inside the brain.
  2. A brain implant collects electrical signals that are emitted by neurons inside the cortex.
  3. The skull device contains a processor that amplifies the electrical signals and digitizes the information. It also has a radio that beams the information to a receiver a few feet away.
  4. Then the information is available as a control signal which can, for example, move a cursor across a computer screen.

The device, called Cereplex-W will work at a rate of 48 MB per second, which is about the speed of a home internet connection. It only requires 30 milliwatts of battery power. It is currently being sold to laboratories for primate testing at $15,000 each. Plans for human testing are coming soon.
