Scientists are on the brink of translating into words the thoughts of
a brain-damaged man who cannot speak. Scientists at Boston University
have implanted electrodes into the brain of Eric Ramsay, who has been
"locked in" after a car accident eight years ago --
conscious but completely paralysed. With the electrodes, they have
been recording pulses in the regions of the brain involved in speech.
"Conversation is what we're hoping for, but we're pretty far
from that," says Joe Wright, of Neural Signals, a company which
helped to develop the technology. However, researchers acknowledge
that they are very distant from mind-reading machines. "It's
very exciting that we are starting to be able to translate some basic
thoughts, but we are a lot further away from a universal mind reading
machine than some people hoped -- or feared -- five years ago,"
said Professor John Dylan Haynes, of the Max Planck Institute for
Human Cognitive and brain Science. ~ BBC,
