Wireless brain signals

In a breakthrough for people with paralysis, scientists at Brown University in the US have devised a system that can, for the first time, transmit brain signals to a computer wirelessly.

A clinical trial of BrainGate, a small transmitter that connects to the motor cortex of users' brains, allowed participants to control a tablet computer with similar typing speeds and accuracy as they achieved with wired systems, but without being tethered to their equipment.
