♪ MUSIC ♪ TOM COSTELLO: Imagine moving a mechanical arm by just thinking about it. Or playing a video game using only your mind. Although it may seem like science fiction, scientists and engineers have been developing this technology for decades: it’s called brain-computer interface, or BCI. RAJESH RAO: The field of brain-computer interfaces relies on the ability of the brain to be able to generate certain types of responses that can then be harnessed by computers, to be able to be interpreted by computers. COSTELLO: Doctor Rajesh Rao is a neuroengineer and director of the Center for Sensorimotor Neural Engineering at the University of Washington, and is funded by the National Science Foundation. He is developing safe, non-invasive devices that can connect to the brain to accomplish things like controlling a prosthetic arm, or sending commands to a computer. RAO: Looking at the development of this whole field of brain-computer interfaces is to think of it in terms of studying how the brain controls the body. COSTELLO: Whether it’s telling the legs to jump in the air, or activating glands to produce sweat, the body’s actions and functions are controlled by neurons. They communicate information to and from the brain and the rest of the nervous system using chemical and electrical signals. RAO: And so they’re sending these electrical pulses to each other and eventually to the muscles that are then controlling my body. COSTELLO: Much like how the brain controls muscles, researchers can use new technologies to tap into these signals to control machines. RAO: The understanding of how the brain controls movement led to the development of devices and algorithms – that can be implemented on a computer that recognize these patterns in the activity of brain cells and then correspondingly move an artificial device. COSTELLO: To demonstrate how this technology works, Rao and his team of students use a BCI that allows them to study nonverbal communication. First, the student is fitted with an electroencephalogram or EEG cap, which is a series of electrodes placed on the scalp to record brain signals. COSTELLO: When a question appears on the monitor, the student answers “yes” or “no” by looking at one of the flashing lights, which are blinking at different frequencies. When the subject’s eyes focus on one of the response lights, the frequency of that specific light is picked up by the visual cortex in the brain, and measured by the EEG cap. 12 hertz represents a “yes” frequency, while a “no” is at a frequency of 13 hertz. STUDENT: Now you can see it peak here at around 12 hertz because no is for 12 hertz. COSTELLO: The computer interprets this signal and moves the cursor in the direction of the response. Using an EEG cap isn’t the only way to measure brain activity. Some BCI’s use a method called electrocorticography. It also records brain activity but unlike the EEG cap, it is surgically placed directly on the surface of the brain, providing a clearer signal and more precise information. RAO: For example, they can imagine moving their hand. And we use a computer to extract the patterns that correspond to imagined movement of the hand compared to, for example, not imagining and just resting. COSTELLO: From there, the computer can distinguish the two types of brain activity: imagining movement and not imagining movement, then use that information to enable hand control by mental activity. RAO: Given the right kinds of information and the right kinds of devices that are useful for the animal or for the human, the brain can start to adapt. COSTELLO: With practice, the brain can learn to do something it’s never done before, like control a prosthetic it’s not familiar with. But the key is to understand how these neural networks communicate between the brain and the body. RAO: If you’re able to understand the brain better, then you’re also able to build better brain-computer interfaces, because they can use those signals that are responsible for different kinds of movements. COSTELLO: As Rao continues to collaborate with engineers, neuroscientists, and neurosurgeons to develop more BCI devices, he is working toward a future where the brain and technology come together seamlessly. ♪ MUSIC ♪

    Map the human brain. Use particles like computer transistors (14 nanometers) placed into harmless bacteria that can pass the blood-brain barrier. Get billions of these particles into the brain. Do this on
    rats and chicken at first.

    EEG nodes + frequency/amplitude modulated wire loops, designed to
    produce magnetic fields of modulated field intensity and size (I assume
    everyone reading this is familiar with transcranial magnetic
    stimulation). Due to the mathematical behavior of this, we can utilize
    the formulas involving Columb and Lorenz forces to predict the spatial
    distribution spikes in energy that form bands in the magnetic field
    produced. Utilizing these principles, we can then take advantage of the
    principles of superposition and cancellation when multiple such
    modulated fields are produced to increase or decrease the intense the
    charge passing through the neurons in the regions of overlap.

    Similarly, we are also able to predict the skew such signals will cause
    in nearby EEG nodes, also in fixed spatial positions. This would allow
    for fine resolution activation of groups of neurons, as well as
    suppression of existing neural firing via interactions between membrane
    polarization and intersecting 'troughs' in the wave patterns' spatial
    positions.

    This is merely a refinement of the low resolution proof of concept
    performed by Stocco and Rao (2013), and later replicated by others at
    the University of Washington.

    Due to the necessity of fixed spatial position for reliably calculating
    overlapping superposition and cancellation of the electromagnetic fields
    within the brain (linked to the particular effects of cellular
    structure on the field produced by it's cell body polarization),
    intracranial implantation of EEG and magnetic induction loops would be
    ideal. However the shifting position of the brain within the skull would
    ultimately necessitate the use of algorithms interpreting the shape of
    the field as perceived by EEG nodes regardless, in order to have a
    meaningful map on which to project changes via magnetic stimulation.

    This technique would allow for a high amount of resolution with limited
    stimulation sources of relatively lower individual intensity, with
    exponential gain in resolution and for each interacting magnetic
    stimulation node influencing a region. From this point, it becomes a
    matter of software, rather than hardware.

    Similarly this relationship between cell membrane polarization, combined
    with spikes from potentiation, upon the EMF (electromagnetic field) of
    the individual neurons is also, by its nature, a product of these
    patters of calculable superposition and cancellation. Operating from
    this model, the intensity in the fields perceived via EEG must also,
    according to our current understanding of the EMF fields involved, carry
    calculable information regarding the base polarization, and specific
    firing activity, that may be mathematically reduced via the spatial
    positions of cancellation and superposition, and their electromagnetic
    intensity.

    This isn't old information. These are things we already know. Am I
    missing some critical issue?

    This mind reading technology is more advanced and sophisticated than this speaker lets on. At the moment there is thousands of non-consensual victims being targeted with this neuro-technology in the USA. The NSA, Darpa, Navy, CIA, DOD, Universities, Hospitals and other military agencies have been working around the clock for years trying to hack the human brain and have been successful. The human target ingests highly conductive nanoparticles which become imbedded in the human brain and his blood stream, extremely covert and highly effective. No wires or chips attached to your head. The perpetrator is able to send and receive radiowaves (electrical activity) coming from the human brain or body. Any physiological setting in your body and brain can be manipulated remotely from hundreds of miles away. Brain to Brain telepathy is possible (no wires or chips attached to the head) , seeing through the eyes of the human target, seeing the images in the brain of the target on a computer screen, dream recording and inception, remote neural monitoring, covertly manipulating a human brain through radiowaves. Look up 'Targeted Individual' on Youtube, look up 'Remote Neural Monitoring' on Youtube hundreds of victims. Vulnerable victims are chosen carefully who can be discredited. The FBI refuses to acknowledge this technology exists, the Mainstream News Media refuses to report it due to lack of proof and how covert it is & the general public refuses to listen to the targeted individuals who are being harrased daily with radiowaves. New laws and Neuro Ethics need to be put in place to protect your family from this form of radiowave/covert harrasment. The future is already here.

    Computer Brain Interface is more logical terminology or a CBI yet BCI is not a surprise to me by a species that thinks that they used to be fish. The Computer must learn to Read the Humans thoughts, the Human does not learn to Tell the Computer what to do. Derp.

    There are two types of world-wide-civilizations upon Earth:
    The main branch sees stuff like this and think “WOW!” and don’t bother to research anything on their own.
    The other, secret branch, have had their wireless hivemind up and running for decades. I call it their “Tower-of-Babel” where they all think they are heading off to a kind of god-hood. Actually, these secretive monsters or network-of-thugs have not figured out that this reality is a sort-of spiritual training-grounds that manifest into the physical to test out social behaviourisms within multiple probabilities. (Study Seth-Books)
    These thugs have been tricked into creating their own path towards social self-destruction while they treat the rest of mankind with a greedy and hateful self-defeating idealism or rather, tyrannical egoism as they pretend they are “evolving,” haa! I guess they taught that self-defeating moral-philosophy in college even though they know it doesn’t work because the world-wide-Cult uses egoism to exist without “good-will.”

    They make crop-circles everywhere with their brainchips and they then gloat that that is Homo sapiens evolving… I would say good luck with your brainchips, microwave light, AILucifer, and rising phoenix, but luck actually does not exist… the thug-network is on the path of learning from failure. Failure to listen to their true inner-voice, not their fake AI-voices developed through hate, greed, and of course, their self-righteousness.

    The ends never, ever justifies the means… that is true Nature and monsters are so named because they will likely end up consuming themselves. The hidden ruling-class knows their utopia is fake and is just lip-service to cokes their brainwashed minions into participating in their fraud. A civilization with a foundation of murderous thugs and assassins will psychologically end up that way as their ill-farted “utopia” reveals itself.
