Scientists Have Connected The Brains of 3 People, Enabling Them to Share Thoughts

This is fancy as one science fiction coming reality!
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.
It works through a combination of electroencephalograms (EEGs), for recording the electrical impulses that indicate brain activity, and transcranial magnetic stimulation (TMS), where neurons are stimulated using magnetic fields.

    At a demo with live pigs, Elon Musk announced that his company Neuralink had built a self-contained neural implant that can transmit detailed brain activity without the aid of external hardware. “It’s like a Fitbit in your skull with tiny wires,” Musk said.

    Elon Musk Announces Neuralink Advance Toward Syncing Our Brains With AI

    Celebrity engineer Elon Musk today announced a breakthrough in his endeavor to sync the human brain with artificial intelligence. During a live-streamed demonstration involving farm animals and a stage, Musk said that his company Neuralink had built a self-contained neural implant that can wirelessly transmit detailed brain activity without the aid of external hardware.

    Musk demonstrated the device with live pigs, one of which had the implant in its brain. A screen above the pig streamed the electrical brain activity being registered by the device. “It’s like a Fitbit in your skull with tiny wires,” Musk said in his presentation. “You need an electrical thing to solve an electrical problem.”

    Take a closer look at Elon Musk’s Neuralink surgical robot

    While the science was front-and-center in Elon Musk’s presentation about Neuralink, his human brain computer inference company, the surgical robot the company debuted made a splash of its own. The rounded polycarbonate sci-fi design of the brain surgeon bot looks like something out of the Portal franchise, but it’s actually the creation of Vancouver-based industrial design firm Woke Studio. To be clear, Musk’s engineers and scientists have created the underlying technology, but Woke built the robot’s look and user experience, as well as the behind-the-ear communication end piece that Neuralink has shown in prior presentations.

    “Ultimately you could potentially download [your memories] into a new body or a robot body.”

    Elon Musk Compares Neuralink to “a ‘Black Mirror’ Episode”

    During Elon Musk’s live event about his secretive startup Neuralink on Friday night, the eccentric billionaire made a surprising comparison — invoking the dystopian science fiction show “Black Mirror.”

    The remark came when he was replying to an audience question about whether the technology could eventually allow users to save and replay memories.

    The inventor of optogenetics, which lets you control neurons with light, has now demonstrated it can work deep into brain tissue, even without implants

    No Implants Needed For Precise Control Deep Into The Brain

    The first time Karl Deisseroth used light to control brain cells in a dish, people had a lot of questions, three in particular. Can the technique be used in living animals? Can it target different cell types? Can it work without implanting a light source into the brain?

    In the years since that initial groundbreaking 2004 experiment, Deisseroth’s team and others found the answers to the first two questions: yes and yes. This month they answered the third question with another yes, successfully introducing an implant-free version of the technique. It is the first demonstration that optogenetics—which uses a combination of light and genetic engineering to control brain cells—can accurately switch the cells on and off without surgery.

    Optogenetics involves genetically engineering animal brains to express light-sensitive proteins—called opsins—in the membranes of neurons. The opsins’ reactions to pulses of light can either induce a neuron to “fire” or suppress its ability to fire. Optogenetics has been used to map brain pathways, identify how complex behaviors are regulated, create false memories in mice, and much more. It’s also been used to develop an optogenetic pacemaker, among other technologies.

    Most of the time, getting the pulses of light inside the brain to control cells has required invasive implants: from tethered optical fibers, to peppercorn-sized wireless implants, to stretchy spinal implants.

    In April, Guoping Feng and colleagues at MIT, along with Deisseroth, demonstrated a minimally invasive optogenetic system that required drilling a small hole in the skull, then being able to control opsin-expressing neurons six millimeters deep into the brain using blue light. This approach used of a type of opsin that slowly activates neurons in a step-wise manner.
