Science & Technology

Two human brains linked in guessing game

Scientists have succeeded in enabling brain-to-brain communication between two people over the Internet.
Mind-reading technology has been going from strength to strength lately and now researchers at the University of Washington have taken things one step further by making it possible for one person to determine what someone else is thinking through a special brain to brain interface.

During the experiment one person ( the respondent ) wore a cap connected to a machine that can read brain activity while a second participant ( the inquirer ), who was located in a separate room, was presented with a series of possible options relating to what their partner was looking at.
When the inquirer asked a question to narrow down the identity of the object the respondent was able to provide a 'yes' or 'no' answer by concentrating on one of two LEDs on their computer screen.

The response was then communicated to the inquirer who could use it to help identify the object.

It might not be quite on par with the sort of telepathy that you typically see in science fiction films and TV shows but the research does represent a stepping stone towards a future where brain interfaces like this one could enable us to better communicate with our computers and even with each other.

Agreed! I do not understand this witchcraft either. I remember a scene from "Demolition Man" where there was a virtual sex machine, and i remember thinking if that ever becomes reality i dont want to live in this world any more! It seems we are one step closer

I can totally see a future where we are all connected to a virtual world by a giant key stuck on the back of our heads.

Matrix is coming. I wonder if this too will be made to mass market without checking long-term consequences in use and not just theory.

"Scientists have succeeded in enabling brain-to-brain communication between two people over the Internet" We do it here everyday without a cap or giant magnet behind the head. Just replace the giant magnet and silly cap with a keyboard, no need to obfuscate basic communication. The technology is interesting, but brain-to-brain communication is a little misleading. The fact that it happened over the internet means nothing. They took a complicated way for a brain to respond to a question with a "yes" or "no" answer and paired it with a giant magnet making a suggestion in the brain of another per... [More]

That key....is it a wind-up key ? Interesting...

Doesn't a carny mind reader figure out what you're thinking by asking yes or no questions? There actually is an app for that on android phones.

So a different way to communicate other than cell phones. Basic stuff. Certainly wouldn't want to link up to someone and have all of my inner thoughts out there (as the technology develops to more than just yes or no lights).

So, they have a computer interpret a signal from a brain into a binary response, and then have a magnet on the other end induce a flash of light for the recipient depending on the answer. You might as well just have a RNG producing the answer the recipient receives, since they are just recieving a binary signal that has nearly nothing to do with the stimuli the computer processed. It isn't linking their minds anymore than a written message does, or verbal communication does. Basically I am saying this is just a novelty with no real value, and arguably their brains weren't really linked anymore... [More]
