Scientists Connect the Brains of Three People, Allowing Thought-Sharing (sciencealert.com)
An anonymous reader quotes ScienceAlert:
Neuroscientists have successfully hooked up a three-way brain connection to allow three people share their thoughts -- and in this case, play a Tetris-style game. The team thinks this wild experiment could be scaled up to connect whole networks of people, and yes, it's as weird as it sounds. It works through a combination of electroencephalograms (EEGs), for recording the electrical impulses that indicate brain activity, and transcranial magnetic stimulation, where neurons are stimulated using magnetic fields.
The researchers behind the new system have dubbed it BrainNet, and say it could eventually be used to connect many different minds together, even across the web.... For now it's very slow and not fully reliable, and this work has yet to be peer-reviewed by the neuroscience community, but it's a glimpse at some fanciful ways we could be getting our thoughts across to each other in the future -- maybe even pooling mental resources to try and tackle major problems. "Our results raise the possibility of future brain-to-brain interfaces that enable cooperative problem solving by humans using a 'social network' of connected brains," writes the team.

Also, brains are only superficially alike in structure. Fine details differ from person to person, so you can't just copy a thought from one brain to another. The only way to do this is to set up a communication channel, and then the two brains practice to convert their thoughts into a mutually agreed upon signalling system and back.
A few comments back I was saying that we already have this, and it's called "talking". It got moderated funny, but I was actually serious.
