I came across this and thought we might be able to discuss it here.

Scientists Demonstrate Direct Brain-to-Brain Communication in Humans

"In a new study, technology replaces language as a means of communicating by directly linking the activity of human brains. Electrical activity from the brains of a pair of human subjects was transmitted to the brain of a third individual in the form of magnetic signals, which conveyed an instruction to perform a task in a particular manner. This study opens the door to extraordinary new means of human collaboration while, at the same time, blurring fundamental notions about individual identity and autonomy in disconcerting ways."

BrainNet: A Multi-Person Brain-to-Brain Interface for Direct Collaboration Between Brains

"We present BrainNet which, to our knowledge, is the first multi-person non-invasive direct brain-to-brain interface for collaborative problem solving. The interface combines electroencephalography (EEG) to record brain signals and transcranial magnetic stimulation (TMS) to deliver information noninvasively to the brain. The interface allows three human subjects to collaborate and solve a task using direct brain-to-brain communication. Two of the three subjects are designated as “Senders” whose brain signals are decoded using real-time EEG data analysis. The decoding process extracts each Sender’s decision about whether to rotate a block in a Tetris-like game before it is dropped to fill a line. The Senders’ decisions are transmitted via the Internet to the brain of a third subject, the “Receiver,” who cannot see the game screen. The Senders’ decisions are delivered to the Receiver’s brain via magnetic stimulation of the occipital cortex. The Receiver integrates the information received from the two Senders and uses an EEG interface to make a decision about either turning the block or keeping it in the same orientation. A second round of the game provides an additional chance for the Senders to evaluate the Receiver’s decision and send feedback to the Receiver’s brain, and for the Receiver to rectify a possible incorrect decision made in the first round. We evaluated the performance of BrainNet in terms of (1) Group-level performance during the game, (2) True/False positive rates of subjects’ decisions, and (3) Mutual information between subjects. Five groups, each with three human subjects, successfully used BrainNet to perform the collaborative task, with an average accuracy of 81.25%. Furthermore, by varying the information reliability of the Senders by artificially injecting noise into one Sender’s signal, we investigated how the Receiver learns to integrate noisy signals in order to make a correct decision. We found that like conventional social networks, BrainNet allows Receivers to learn to trust the Sender who is more reliable, in this case, based solely on the information transmitted directly to their brains. Our results point the way to future brain-to-brain interfaces that enable cooperative problem solving by humans using a “social network” of connected brains."

Personally I have mixed feelings about this , in one way it can help people with handicaps who can't speak or people who had an accident that made it harder for them to speak with this technology it will help them which is a good thing but on the other hand the most private thing we have is our personal thoughts and with this technology our thoughts can be known and even hacked in a way which is bad . So if there is a safeguard against this technology being hacked then I am for it . But sadly major companies can use this and even bribe the makers for sensitive data like our personal thoughts to advertise , send us spam , get personal information like bank accounts , social security numbers , and even know if you hid treasure anywhere . Also data taken by this could be used in a criminal case basically demeaning the 5th amendment .

One step closer to the Matrix

I have a feeling my cat is trying to use this all the time and then meows in aggravation when I don't get the direct brain-to-brain communication that she's hungry.
