Wireless EEG invasive electrode

One more (BIG) step to Brain-Computer Interfaces: Australian researchers at the Royal Melbourne Hospital and the University of Melbourne have developed an electrode that can record brain activity from the motor cortex, without the need for invasive brain surgery. 

The electrode, called a stentrode, is implanted into a blood vessel in the brain using minimally invasive surgical techniques. The electrode can record signals from the motor cortex and transmit them wirelessly through the skin to a device outside the body.

Noninvasive EEG Based Control of a Robotic Arm for Reach and Grasp Tasks

A team at University of Minnesota has created a control system that relies non-invasive electroencephalography (EEG) to allow people to use a robotic arm to move objects.

One more long step in brain-computer interfaces that can be used to control the complex motion of powered robotic arms. More information here.
