"Although still largely experimental, devices that decipher brain
signals are advancing quickly and allowing some fully paralyzed people
to interact with the world Amyotrophic lateral sclerosis (ALS) can
trap the mind inside an immobile body. It destroys the nerves that
control muscles, eventually leaving patients without the ability to
speak or even flick their eyes to one side. In the past few years,
however, researchers have started to equip a few such "locked-in"
patients, including those paralyzed by stroke or other diseases, with
communication devices that unlock their minds.
For decades, science-fiction writers have envisioned computers that
communicate directly with the brain. Now a rapidly expanding clique of
researchers is making it a reality. A few laboratories started
developing these so-called brain-computer interfaces (BCIs) in the
1980s and have been refining them since then (Science, 29 October
1999, p. 888). Now several dozen teams have entered the field.
Together they're improving upon early BCI models and coming up with
new ways to read brain signals. According to BCI pioneer Jonathan
Wolpaw of the Wadsworth Center, part of the New York State Department
of Health in Albany, "it's a very exciting time; a lot of people are
getting involved."
Most BCIs read brain waves, the electrical impulses created by neural
activity that can be detected--albeit fuzzily--through the scalp. By
diligently controlling their mental activity, patients can choose
letters to spell words, guide a cursor, or direct crude robots. But a
rival circle of scientists is rapidly advancing a type of BCI that is
implanted inside the brain. Such devices tap into the more detailed
neural signals relayed by individual neurons. The most sophisticated
of these implanted BCIs have recently enabled monkeys to play video
games and even manipulate robotic arms. Whether the implanted devices
will actually lead to more versatile and workable BCIs than the
external type is a matter of fierce debate.
In the past few years, brain-wave BCI technologies have been advancing
rapidly, providing faster spelling, better cursor control, and headway
into prosthetics, environmental-control devices, and smart
wheelchairs. The advances are fueled in part by cheaper and more
sophisticated computer hardware and software, which has given BCI
researchers access to portable machines that perform complex
mathematical manipulations on the fly. Good old-fashioned funding
helps, too: The National Institutes of Health awarded $3.3 million in
late 2002 to a partnership headed by the Wadsworth group to further
develop software that can test several BCI systems to see which is
best for a patient. Researchers can also use the software to build and
test their own brain-tapping technologies."

The basic framework for BCI2000 is now complete, and Wolpaw expects
details to be published soon. It has four easily adaptable modules
that handle the four essential functions of a BCI. One takes the raw
brain signal, amplifies it, and encodes it digitally. Another extracts
the desired features of the brain signal, such as a mu rhythm or P300
signal, and translates that signal into a command, such as movement of
a cursor in a certain direction. The third controls a device, say, one
that navigates the Internet or operates a prosthetic arm. And the
fourth allows a user to start and stop the BCI and to specify details,
such as the speed, of its operation.
The software has already had an impact on the field. In spring 2002,
South Florida's Donchin needed to upgrade his BCI, which was
incompatible with state-of-the-art PCs, so he could start testing
disabled patients. Donchin met with Wolpaw and Schalk at a BCI
conference in Rensselaerville, New York, in June 2002 and described
his predicament. Schalk volunteered to do the necessary programming on
BCI2000. Within 2 weeks, Schalk managed to get Donchin's BCI up and
running, enabling Donchin to bring it to New York City to test it on
his first patient (this author's father) in September.
Georgia State's Moore and her colleagues are using BCI2000 to develop
an environmental-control system that allows a user to turn on and off
lights, a television set, and a radio with brain waves. They've also
built a communication system in which a person can select words from a
list of nouns, verbs, and objects, and that will predict words and
even conversations, potentially providing faster communication than
traditional spellers allow. Their Web browser causes a cursor to hop
from one Web link to the next in response to altered brain signals.
So far these prototype applications have been largely tested on
simulated brain signals, but Moore has just started testing them on
healthy volunteers and will soon include patients with spinal cord
injuries or early-stage ALS. Eventually, Moore plans to run all of
these applications on a laptop mounted to a smart wheelchair under
development that will also be controlled by brain waves.

The other point is that it can create opinions, change them, make one
hate or love.
For example, one may start loving China or Hate it based on this
experiment. The same is true for Musical and any other religion,
community, civilizations and far more that words do not allow.
It has brought all human values, ethics and philosophical thinking to
collapse in the laboratories. The terrorism in the world, wars, and
all that we see, hear or view in media is just hiding this grave
experimentation leading to extinction of human wisdom.
We need to pay attention to it lest it is too late. Please pray or
seek that this global and thus universal suffering must come to an end
as soon as possible. Thanks!
