- Neuroengineer Rajesh Rao of the University of Washington is developing brain-computer interfaces, devices that can monitor and extract brain activity to enable a machine or computer to accomplish tasks, from playing video games to controlling a prosthetic arm. "Mysteries of the Brain" is produced by NBC Learn in partnership with the NSF.
Good luck on your exams...
Thanks
I would've never thought someone would make a device where we have to actively engage with it instead of other technologies of today that make us more lazy. This is so cool!
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?
You'd need a headset unless you were willing to mount the micro-TMS loops inside the bone of the skull to maintain their fixed position. But a headset would work equally well non-invasively. Predicting areas of stimulation and inhibition would simply be a matter of superposition and cancellation of fields from each mTMS loop. I don't have actual code dev'd for it, but it's not extremely difficult mathematically.
Sara Danhoff nice wiki info. thanks for sharing!
Understood about 10% of the words used, anyone else?
You're forgetting that the reintegration tangent recalibrates on a microsecond interval, thus leading to microelectronic erosion.

WHO truly controls it?
can it be hacked?
can it be overriden?
Goes to show that our brains are super powerful bio computers.
A thought to text interface coupled with pre-recorded voices using Lyrebird AI could help those who can no longer speak.
Why isn't it incorporated in my VR headset yet.
Any side effects? Short-term and long term and across generational side effects? How would this impact epigenetics?
How does it affect mitochondria?
Likely no side effects. This is because your brain is just sending signals to the computer, it is perfectly safe.
maybe we will be able to play SAO when hes done whit this Brain Computer Interface
yesss
just hope no evil hacker traps us in the game LOL.
@@masonreppeto882 Too Late! (wake-up) haaa!
what if were already in full dive vr and we just dont know?
@@zyon4531 oh. maybe.
Awesome work, I request you if you do something about targeting individuals who's facing electronic harassment. Something like shield to body
I wonder what will happen if BCI and machine learning is combined
BCIs will be able to control any device they encounter

Amazing. Now Imagine a hoverbike or a jetpack controlled with the brain.

" Brainstorm " movie, Christopher Walken
Yes please.
I. Have. An idea for an experiment it goes like this..see if a person. Can play gustav holst. Planet suite on an electric organ useing only there human brain
Is that SwaggerSouls?
That's what I was saying to my self! If it's not him then all my life was a lie.
Excelente
sir i want to know the eeg amplifier
I love psychology, my fav school subject, since I can watch this kind of videos :P
But this is neuroscience, psychology is pseudoscience.
Badum tsss
can a brain-to-brain communication be done through BCI?
Yes, Stocco and Rao did so in their experiment in 2013, and it was replicated by the University of Washington later, via the use of transcranial magnetic stimulation.
Love Hurt's, Together we can brake these chains of love. Hahaha or Make it Stronger
I can contact u but how do contact u?
it is good
Siemens should develope this technology
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.
house?
“….Devil up menT….”
What about their hairdo? Heir don't! AAAHahahaha...
brain controlled interface BCI
Brain Computer Interface BCI
Are we going to release any Hormones by the year 2050 !?
focus on cbi not bci
Brain computer interface gives an advertising lifestyle.....
hey me
We are on the Verge of Becoming God's, so the Gods Are coming to stop Us , We cannot allow them to interfere with our Becoming, I want memory to memory.
my brain thinks lots of stuff lol
According to the Laboratory of Neuro Imaging at the University of Southern California an avarage person has 48.6 thoughts per second on avarage.

It's official there is no soul
Unless you want to count the electomagnetic field produced by your brain and likely responsible for the phenomenon of consciousness according to the latest revision of CEMI theory. I mean, you could reasonably argue it's a soul, I guess? Won't stop us from doing Science! on it though, lol.
Correction: you are, not your
Lmao what is the soul? Its the “energy body”
So then youre being wrong peopled .
So then its your neighborhood ...
Wrong issues
Science says there is no God yet always playing God.....
Cason Tha Commentator idiots
This makes no sense
There is no god, humans are not “playing god”. Humans are simply developing new tech to improve lives.
are they doing human experiment ?
illegal
Sunny Jacob incorrect. We have had BCI tech for decades. We have just began to scratch the surface of what it's capable of...
Siemens should develope this technology
