B2B - BrainToBrain: A BCI Experiment - May 2009

This is a BCI experiment whereby one person uses BCI to transmit a series of digits over the internet to another person whos computer receives the digits and transmits them to the second users through flashing an LED array. The encoded information is extracted from the brain activity of the second user. This shows true brain-to-brain activity. This is done as a proof of concept - to show that B2B *is* possible - which it is, as we show here. The first person uses motor imagery to generate the digits and the flashing LEDS generate steady-state visual evoked potentials in the brain of the second person - the PCs read these data from the electroencephalograms of EEG person.

Also any b2b is going to involve technology to facilitate - from Reading, transmitting and writing information.

[Christopher James]

Nobody said anything about conscious thought, you might call that mind-to-mind, whether one uses the senses or stimulates the brain directly both result in brain stimulation.

[Christopher James]

Remember this is a proof of concept trial meant to try and start doing BCI both ways, "from little acorns ..." :)

As for what constitutes "true" brain to brain - you tell me. The information is being read from the visual cortex of the receIver using standard SSVEPs.

[metsesell]

"True" B2B would be decoding information directly from brain signals (any cortex you like) and "writing" them directly into the brain without the need of intermediate perception organs like eyes, ears etc. In this experiment there was two different types of readings done from brain (from sender's and receiver's brain) but the information was sent into receivers brain through visual stimuli - so this demonstrates "brain -> pc -> eye -> brain -> pc" communication not "brain -> pc -> brain".

So, like I said then, this experiment describes brain-to- brain! However circuitous the route! There is no escaping that fact, whichever way you look at it.

Tinfoil a bit tight?

[csguy12]

Actually, binaural beats could be used for that instead of light then.

[Lluis Nieto Soler]

so kids, start learning binary code!

[GenoSkill]

with BLIND people it didn't work. Brain to Brain concept FAIL.

[WALTKRIEG]

Wrong ! All the brain cells are used. By exemple, a man who suffured of brain dammages, may probably recuperate because other cells take the places of the destroyed cells.

[viperior]

We must use this to train AI to our own brain workings.

Once they learn how to be more like us, perhaps they can surpass our intelligence and spark the singularity.

I'm hungry!

[pinkubento]

Wrong.

[CatharticWeek]

Aaaaaaweeeeeeeeesome!

[LaserGoPEWPEW]

5% of our brain is used. The other 95% = possibilities

[MsVader]

I find this v exciting - but at what point will we have communication with BtB/HCI that is more than left or right, on or off, 1 or 0, . or -? At what point can we convey more complex data/emotion and how? And will that require "training" to decode it?Having the pc/internet to convey information isn't such a bad thing, it means that this can be done with 2 parties anywhere in the world where there is a network connection.Can this be measured in a more direct way bet 2 people in adjoining rooms?
