Some BCIs made of silicon pierce through and damage brain tissue during implantation.

Primarily, BCIs based on electrophysiological measures have been developed and applied with remarkable success.

Cyberkinetics is leading research on BCIs in the private sector.

But other researchers are working on simpler, noninvasive BCIs.

BCIs can be used to manipulate... or kill.

Consumer BCIs use noninvasive electroencephalogram (EEG) sensors attached to the scalp to detect brain-wave patterns.

Brain-computer interfaces (BCIs) provide a way for the brain to interface directly with a computer.

And it is here that military researchers need to harden the systems that enable military application of BCIs.

BCIs can allow game players to move around and manipulate objects within virtual game environments, using thought alone.

This survey demonstrates the interest of individuals with SCI in receiving and contributing to the design of BCIs.

However, current microelectrode arrays for BCIs lose the ability to record high-quality neural signals in the months-to-years following implantation.

Brain-computer interfaces (BCIs) can reanimate paralyzed muscles after SCI, but whether they can restore touch was unknown.

ECoG-based BCIs are being developed to provide increased options for treatment and assistive devices for patients who have functional limitations.

Wolpaw makes the point that BCIs provide new output pathways for the brain, but the brain has to learn them.

Background: Non-invasive brain-computer interfaces (BCIs) have been developed for realizing natural bi-directional interaction between users and external robotic systems.

We need to prevent BCIs from being disrupted or manipulated, and safeguard against the ability of the enemy to hack an individual's brain.
