- Want to know how brain-computer interfaces actually work? This video goes over the methods that neurotechnologists use to turn brain data into commands a computer or a machine can understand. We cover data collection, processing, filtering, analysis, how to generate an action in a device, asynchronous BCIs that use population encoding, and synchronous BCIs that use P300, SSVEP, N100, and N400 signals. A little unsure of what all those terms actually mean? No worries! That is what the video is for :)
Harrison and Colin (The BCI Guys) are neurotech researchers and entrepreneurs dedicated to creating a brain-controlled future! Neurotechnology and brain-computer interfaces are devices that allow users to control machines with their thoughts and interact with technology in new ways. This revolutionary technology will change life as we know it, and soon will be as common as the touchscreen on your smartphone. Join us in learning about the brain-controlled future!

When I entered the video, I did not expect to cry because of the amazement
🥲
Fascinating. Thanks for the video.
Greetings from Brazil! You guys r doing such a great job on this course. Keep it up!
Greetings! Thank you thank you!
Habe ich für einen Vortrag genutzt, besten Dank!
awesome explaining !
great videos
Thanks!
fantastic, it's not really imagining, the brain is the source of the signals (or transmitter) and the missing limbs are equivalent to receivers. Connect an artificial arm closes the circuit. you may be able to emulate sensing from the artificial limbs back to the brain and create a feedback link and a fully integrated system. The synchronisation aspect is fascinating. It seems the signalling protocol is far simpler than what comms systems use today, perhaps compensated by the number of neurons to keep the brain fast and efficient, any thoughts? Would love to explore more ideas with you guys if possible, spent many years working on dsp and comms system
How can I get text of this video?
Many thanks Sir
Most welcome thank YOU
when someone adjusts their brain wave to use their brain wave to accomplish some tasks like the monkey game you mentioned, is it called neurofeedback?
Hi! Does BM-BCI help optic nerve to regenerate? Thank you!
There are Retinal implants and v1 cortical implants that are being produced to make visual prosthetics!
I'm currently taking my Masters in mechatronics/mechanical engineering in the UK, I'm looking to get into a career of research into BCI for prosthetic/exosuit applications and would liked to take a PhD relating to it. Do you guys have any tips or advice regarding this as well as what content to study and learn whilst I still possess my student e-library access. My Supervisor has suggested I write a review paper but I'm stumped on where to start.
Amazing 🤩
Which university 🎓 ?
Why does desynchronization of neurons signal movement and not the synchronization of them. Shouldn't it be the other way around?
Synchronization produces bigger oscillations because neurons are firing together - if they are all during at the same time it is likely that they are not actively working on a task. When the wave is depressed (higher hz faster oscillations) the neurons are all working very quickly on all different tasks indicating high activity. So desync usually means activity and sync means it's in an idle state
How can baby detected or found if you were implanted
Hey came across you guys lately but was worth it. What major would be best for undergraduates to start a career in BCI?
Neuro engineering if you can swing it. Neuroscience ofc, software engineering and electrical engineering can work too
@@BCIGuy How about computer science in undergraduate and then AI in masters?
Will it do?
Hey ,i am a medicine specialist . Will do my superspeciality in neurology. Can u guide how can choose a career option as ai research ,or bci ,neuromorphic computing etc?
Your mail please?
I would take another approach to accomplish a task. There are muscles and nerves that still exist before the amputation. Those muscles are controla le simple and direct. They can also correlate to normal body movement. Has anyone tried using existing muscles to activate a motion.
Can you pls share the source material used for making this video? Thanks in advance :)

What are the most underground, secretly developed methods in place? I have been outfitted with either an unknown no-touch bci or discrete device without my knowledge. Subvocalization and EEG is interpreted with accuracy on the primary vocalization level. I'm a victim of targeting and I'm not joking nor a mental health patient.
As an FYI, a long period of conditioning went on before I was let know about it. My thought processes were manipulated to better accommodate the interpretation technology
am going thru this as well, and so much more. I dunno if I can find any help. It's ruining my life. I went thru years of harassment before it got to this point...
May I ask which subspecialty of neurology is most applicable to work with BCI both invasive and non invasive?
Is it possible to be set up with a bci or brain to brain without consent or contact?
I'm desperate for some answers
Check out the comment I left on our most recent video
Yes
Epic
Can Anyone suggest me final year collage project around this ?
Build your own EEG - there are tutorials. If you can get access to a commercial headset there is a lot you can do with p300 based control systems. Depending on your technical capabilities you could do some assistive software for typing or control a robot thing
@@BCIGuy You meant own EEG devices from scratch or use existing headset and build something on top of it, I am 4th year computer engineering student and thanks for replying
are there any that improve iq or focus like magnetically shutting down certain areas so others can function more optimally?
Im not sure you’d want to be shutting down certain areas of the brain without a medical need. Certainly for people with mental health challenges like depression there are devices that can enhance or inhibit certain areas to try to correct what’s going wrong there. Or course, for someone who had ADHD or depression these interventions can have great cognitive benefits. For others right now the benefits are minor but there are people working in ultrasound stimulation, TMS, and TDCS devices that do this to some level
@@BCIGuy Awesome! Thanks for the reply
Ive also been curious about how brain chips could enhance processing power. How would that work? The brain sends a signal to the chip which is decoded (i understand this part), but then in what way would it process that, and how would it send the information back? to specific neuronal regions or?
Like I can see images in my mind, but if i had a brain chip that enhanced visualization, then the signal would send from my mind to the chip, the chip would read that im likely thinking of a purple flower, and then it would process what a flower would look like and send back electric impulses to that neuronal region which produces a flower image in my mind, which would then enhance my visualization of it?
@@BCIGuy or maybe we could enhance intelligence by lightly stimulating the prefrontal cortex regions associated with impulse control and executive functioning.
though that would just seem to enliven the neuronal network we already have in that area, but i havent been able to understand yet how we could expand the neuro network without enhancing cranial capacity, but by chip alone.
BCI technology is still pretty terrible at "writing" information to the mind. The brain is just far too complicated for us to understand exact processes and change them. We are only able to process some basic patterns and regional activity and nudge them in a certain direction. So no, we currently don't have the knowledge or means to do that. Our best guess is a ton of artificial synapses and a very powerful ML model. Another challenge when it comes to "writing" to the brain is it's plasticity. The brain is an ever changing and evolving system. To accurately depict and decipher all current and new connections (and even new neurons that form through Neurogenesis) we would have some serious deep diving to do. @@williamdevonshire356

There is something wrong at 4:17. If it's not significant, there is no need to re-upload it.
Thank you. I think that's just a jump cut. We change the framing a lot through the videos but I agree this one felt a little too abrupt. Is that what you were talking about or is there something else? Also thanks for your continued feedback 😊
@@BCIGuy yeah that was it. I love what you guys are doing. Soon I have presentation about the BCI technology. I'm using lots of your contents, with reference of course. Keep up the good work. 😁👌👌👍🤟🤙
@@PedramNG aw thanks! Good luck on your presentation! send it if it is recorded
@@BCIGuy I will do an English version of it and upload it on my CZcams channel. 😁
@@PedramNG yay can't wait to see it :)
Please think happy thoughts to my atm😉

Somebody has been experimenting on me without my consent ailin hand crocj
And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
u guys go ahead and get microchiped,the LORD will burn u with fire and brimstone and worms will eat up ur flesh!!!
ALL PRAISES AND GLORY TO THE MOST HIGH!!!
you good bro?
@@BCIGuy am i good?u fucking joking?u people have no fear of god and u re all blind.Read the scriptures so that u might have understanding and realize where and when u live.
@@TheScabbage a reasonable person would never get a chip inside him.a reasonable person will never recieve the mark.
All this is profecy being fullfilled.u people are so ignorant and stupid that u reject the scriptures without even reading them.Read the book of enoch(the watchers) isnt it very similar to what is happening today?and remember what god did and Fear GOD u ungodly sinners for ur time is running out.
Face and that talk out my mouth cops won't help
