Typing with the Brain

A journal article on a new Brain-Computer Interface describes a system allowing paralyzed people to type.  That is darn cool.  It would be even better if researchers knew how to restore brain function, but even this is amazingly helpful. Eight words per minute may not sound like an impressive rate, because it isn't for somebody whose hands work, but for somebody who is paralyzed it could make all the difference in the world.  Kudos to the researchers who accomplished this, and to those who were willing to try it out.
