I greatly appreciate you included the part about having issues troubleshooting the device. It's nice to see that I'm not alone in getting stressed out when things don't go according to plan.
You're definitely not alone. I spend a lot of my time at work stressing about things not going according to plan (I'm learning to just go along with it)

Many of the papers and reviews have Colzato as an author or coauthor.
The 2017 Colzato paper was retracted in 2021:
"The Editors-in-Chief have retracted this original article following an investigation by Universiteit Leiden providing evidence of manipulated data. The investigation concluded that the authors originally tested 88 participants but only data of 40 participants was included in the analysis, without adequate or transparent explanation in the article why participants were excluded from the analysis.L. Steenbergen and R. Sellaro agree to this retraction, L. Colzato does not agree to this retraction "
we love the good ol psychology replication crisis
I always think "replication crisis" is an incredibly polite way of describing what is actually happening.
The Dr Becky jumpscare was so unexpected, it's always a surprise to know that disconnected science communicators talk to eachother
Surprise! 😅
@@DrBecky Aaaaah! Another one! :D
Yeah! I was all, "what is this, Lateral? Are Tom Scott and Matt Parker going to be in this too?"
I struggled with intermittent insomnia in my 20s and 30s, but since I started doing binaural beats/brainwave entrainment when I go to bed in my early 40s, I have pretty much eliminated the insomnia completely. It might still get me a few nights per year, but I have never slept better and more consistently as an adult. If it's a placebo, so be it. I also use ASMR leading up to bedtime to help calm my mind and get me drowsy. Where once it might take me half an hour or longer to drift off, it's normal for me to fall asleep within 10 minutes.
The frequencies don't need to be binaural (in different ears) for you to hear a beat.
When you're tuning an instrument, you can play the same note on 2 different strings at the same time, and you will hear the difference in the frequencies as a "beating".
The slower that beating is, the closer the frequencies are, so you can keep tuning one of the strings until you can no longer hear the beating.
Musicians also used to use this to tune their instruments to a tonefork
I think that would be called a monaural beat.
Great to see two of my favourite science communicators come together. Fascinating topic but definitely seems as with most scientific research, we still need more data!
Is it possible that the brainwave monitor you were using was merely measuring facial muscle movement rather than brainwaves? That may explain the spike on the graph when you started talking, rather than when you were sat in silence. I ask, because I'd be surprised if the device's claims are legitimate.
Yes definitely!
@@braincraftAre you willing to do a follow-up video about a side related topic on this as I got a question relating to the different types of brainwaves . ♑️✍️🇳🇴🇦🇺
I think the term "brainwaves" makes them seem like something they aren't. There is some level of tangibitily to "waves" and that leaves the impression that they are something physical you can interact with. In reality brainwaves are more similar to an EKG, in that they are just a representation of the electrical activity of the brain. When you are awake and active your neurons are constantly firing as they are needed, and that looks almost like static on the EEG. When you stop demanding your neurons fire is when Alpha Waves start appearing, and you can think of it as sort of the default state when you're not busy thinking about something. Neurons start having a coordinated activation and deactivation pattern that forms an actual wave on the EEG. The hypothesis is interesting, but sound wave frequency doesn't get translated as neurons activating at the frequency of the sound, rather you have constant activation of the neurons that detect that specific tone, meaning there is no real way for a physical sound wave to start influencing the neural pattern to reflect it.
Fun fact: Brainwaves and VHF are around the same frequency. Broadcasters found that out back in the 40s. Technician s standing next the "LIVE broadcast camera", would see the image in their heads. It's not really practical. If you move your head, the image disappears.
@@grant9214would that not be because they were looking at the same thing as the camera?
Which EEG systems were used, and how many channels were recorded? 32 channels used to be standard for in-patient studies, and as many as 128+ for intracranial studies.
25 years ago I would put "cartoon network" at a low volume as background noise. Today I listen to audiobooks with a shutoff timer.
11:27 - To that end, I have found that using a red eye/night flight video... say SFO to JFK on a 777, or BOS to KEK on a 787... or even just the 737 Max 8 from OGG to HNL... Put me right to comfortable sleep. However, the shorter flights, I tend to wake up, the longer flights, I just sleep. So yay, I've found mine! :)
One of my favorites is a Hawaiian A330 from Tokyo to Honolulu. By the time it's arriving in HNL, I'm about ready to get up seems... and a nice visual to wake up to it is. :)
I hope any who have trouble sleeping through find their 'fix'. It took so long for me, but I get sleep now, and that's the thing.
My hypothesis is that the entry level eeg devices do not measure minute electromagnetic waves emanating from the brain. I speculate that rather they measure skin resistance which fluctuates as affected by neural electric activity. To this end I used an ohmmeter to measure the resistance between the points of contact on my head where the eeg device would normally contact my skin. Then I simply replaced my head with an appropriate value of a electronic resistor. The reading and display I observed were identical to the readings seen when the device was attached to my head.

10:24 It looks like the underlying issue is an inability to control your thoughts, and this might be a key to addressing your anxiety.
Does anyone know what brainwaves we have when we are in a fifth completely different state? Sheer panic and distress? I don't know how to ethically experiment that. But I am suuuuuper curious.
On a common meditation app, they offer different binaural beats as meditations. I’ve never seen instruction for using headphones. If I listen to it without, then how would the sound be different to each ear?
@Ankush , Hi is it possible to learn while sleeping and listening to audiobook at the same time , I don't think so, is it ??
if we shift the frequency of what we hear left and right in our headset, can it work with normal videos too instead of beats? Also I am pretty sceptical about this all and am pretty sure this is placebo only
Who did the art for the brainwave frequencies starting around 3:06? Those are beautiful sketches.
Is it kind of like when 2 people whistle realy loud and it makes this weird 'tearing noise/feeling'
Oh wow! Dr. Becky is your friend! Awesome!
Having Ness as a friend is more awesome 🤗 especially when I pepper her with neuroscience questions I’ve always been curious about and then she makes a video about one hehe
Audio illusions are something I was not aware of an hour ago.
my cousin in Christ, _yanny laurel_ 🤌🏾
Assuming the testing methodology is sound; if a proposed effect is still difficult to detect/measure -then it's likely negligible; at best.
I don't know what was wrong with this video, but it gave me a headache... not the tone section, but it started pretty early in... :\ interesting stuff though. How did that headset work for you(after troubleshooting)? how expensive is that?
The audio illusion can't control my mind. You can't have your mind-controlled if you've already lost it. Checkmate.
same energy as "brain eating ameoba? poor fella going to die of starvation"
I think you could definitely model for pseudoscientific medical devices and move units so you should use that power wisely
The look of those EEG(?) headsets reminds me of tDCS "at-home" headsets, I see you made a video 9 years ago but I'm really curious if there is some new data/research/info on tDCS especially the DIY stuff, are people thriving or die-wing? (oof sorry, was that even "a" wordplay)
I also wonder if there's some variables like different people have different thresholds for brain waves or different responses to the beats that create different brain waves or something else entirely like diet or idk. We're going to need a lot more research and I don't expect the funding for that exists, there's not enough profit in it.
I used to LOVE binaural beats - I used them to relax/fall asleep and I found them really effective. The one day I was listening to them when studying, and when I took the headphones off my ears were ringing... and remaining ringing for months. Perhaps I had them on too loud, or for too long, but please approach with caution. (For context: I had also previously experienced viral labyrinthitis, so that might have also been a factor).
That is a very cool shirt 🧡
(upon observing any unexpected, fun effect) THIS IS MEDICINE
For total brain control just listen to (for starters): The Beatles, Rolling Stones, Santana, John McLaughlin, Led Zeppelin, Cream, The Dead Daisies, Black Sabbath, Jimi Hendrix. It's really that easy. Peace out!
Regarding the video descrtiption: It looks like you've put the wrong link after "New systematic review" because it goes to the same paper as the link after "2023 study on binaural beats worsening cognitive performance".
Dunno if I can post this link, but the link to the review is pubmed.ncbi.nlm.nih.gov/37205669/ .
Welcome to Minnesota!
I had no idea that home eeg rigs were available. Time to indulge my inner mad scientist!
Has anybody studied binaural beats in a single ear? That’s a very different phenomenon, I’d guess. (I ask because my left ear doesn’t work, so truly binaural beats aren’t a thing for me.)
0:12
-Of course it can, it is called music.-
Also, speaking of EEGs, there is a museum I have been to called the Museum of Science and Industry located in Chicago that has a section on the human body and one of the...experiences I guess you would call it has you and another person put EEGs on and there is a ball in the centre of a table and to get the ball to the other person's side and therefore win you have to have a lower brain activity. Genuinely interesting, when I was younger I was always confused how it worked. I also used to be really bad at it, I could not use it the last time I was there because it is a rather popular activity there.
Fun fact: the Minnesota Mining and Manufacturing Company produces all of its tape in a small town in Minnesota called Hutchinson.
Okay, bye.
The problem with "debunking" studies in matters of productivity and focus is that usually they don't bother with taking the original claim seriously. Are these the correct binaural frequencies to achieve the intended effect? Do the headphones work as expected? etc etc. I have seen many studies debunking strawmen, which, in turn, make me feel unsatisfied and prone to believing the original claim, even if it is a placebo effect.
Of course, in science, the claims need rigorous proof, but the replicability crisis in these fields doesn't help us much.
Perhaps you need some control runs to compare against.
Lol, great way to write off your vacation. And now you have evidence for the tax man. 😂👏
Could this illusion be used by hearing aids for people who have lost the ability to hear certain frequencies?
Waiting to see binaural beats by dre
It was popular around 2008 - every banner was trying to sell you some magical binaural waves music for $5.95/month. Every teaser ad had at least one offer to buy this stuff. There were different tracks - to help you sleep or study, or promised some magical pleasant experience. Obviously, it was fake, it did nothing
YT videos help me sleep too. I get desensitized to ASMR quickly though.
I think it's important to distinguish what a binaural beat actually is, from the "brain entrainment" effects that some people claim binaural beats have. I'm sorry if I missed it, but you did not seem to make this distinction and are conflating the two things. You are not "debunking binaural beats", you're debunking the "brain entrainment" claim.
Ah yes, sleep. That's totally what the recommended binaural beats are promising me too, yup...nothing else.
Just handsfree...sleep.
Controlling for individual neurodiversity seems like a necessity for this type of experiment. The single tone makes me anxious, and the bi-neural thing was even worse. I just wanted to turn it off when you played the short example. It feels like I'm stuck in some compactor and it's slowly crushing me.
💯
Well its a part of a system not a whole system you know like wood planing you need the motions you need the tool and you need to have a un even pice of wood you know ?
To just ues binerl beats is not enough the breath work the point of trama your tryng to manage or the sleep you trying to induces is the wave function your trying to alter ... it's a catalyst that needs a arc of dissequallibrem.. you know ?
Ah!! Relaxiation!!
Have you heard the joke "the nothing box"?
wasn't there a connection between 3M and forever chemicals
WRT noise inside the airplane, first class is on the front, and the middle and back parts of the airplane are nearer the turbines. Furthermore, the cruise speed causes a significant Doppler effect on the frequency of the turbine noise
Binaural beats - tech bros acting like they invented the harmonies that have existed as long as humans have been making music just so they can sell you headphones.
Well, with Ryanair (low cost airline with only one class configuration) you can notice quite a lot that the noise in the first rows is much lower than at the back. And I bet it doesn't have to do with the insulation but with the position of the engines. Most of the noise in an airplane goes backwards, that's why first and business class are at the front, because naturally the noise is much lower. If specific insulation helps a bit more, that could be. But most of the reduction is not because of it.
Thank you for calling out for Hubberman's Lab bs content
Personally I have experienced effects
ASMR, Hypnosis, and Binaural Beats. The Unholy Trinity of the scientific grey area!
Man, that second EEG is rather reminiscent of the DC Mini device in the movie Paprika that let people interact with other people's dreams...
A lot of your audio is "muddy." A low cut filter should clear that up.
huber man is the worst. he’s the embodiment of those 5pm videos of life hacks (where it’s all bullshit)
3rd comment. First time for me. 😁

I tried this like 20 years ago. I generated sine waves with 1-5 Hz difference in the different ears. There was not even amazon to order an EEG from, much less affordable EEGs that were not a scam, so I had to go off of just my state of mind when using it. And my conclusion was: it's snake oil.
First
try 2nd ya fool

Get your bag I love your videos but it is odd that a science channel is doing an ad for the company responsible for the human race and animal kingdom being part Teflon.
3M and DuPont are different things, you know this, right?
@@Gusto20000 No need to be condescending, they are both horrible companies with Teflon scandals. Maybe do a quick google before defending a billion dollar corporation next time. Oh would you look at that I’m condescending now too!
Good research and presentation, Vanessa. Now, I don't want to brag, but I have done fairly extensive research in at least part of this area, meaning I have some expertise in this area. I'll start off by saying that I believe that binaural beats, at least at those frequencies is like the the crystal rocks you investigated. It's a bunch of gobbledygook mainly used in pseudo hypnotism, as opposed to real, guided hypnosis like telling you to relax and so on. The type of faux hypnosis has all sorts of claims, like being able to cure disease, sleep better, and manifest more money. In short it's sophistry. Part of this can be explained though simple science. Those wavelengths are so long that their direction cannot be determined by the human brain. Wavelength =speed of sound/frequency (divided by). So that means 1 wavelength=equals 343 meters per second (the speed of sound in air)/ hz. So 1hz would be 343 meters/1 or 343 meters long, for one sinusoidal wave (or cosine wave as some like to use). So let's make the other wave a 4 hz wave. That will be 343/4=85.75 meters. Well, imagine you are sitting in a room with two stereo speakers. If you played 1 or 4hz out of one speaker, you would not be able to determine which speaker it came from and you wouldn't even be able to determine if it came for in or behind you? Why? Because the wavelength is so large that one full one or cycle wouldn't be able to fit in the room unless it was a cathedra, and a very large cathedral at that. (Incomplete sentence there) See, the distance between your ears is only 30cm(10 in) if you cul it around the front of your head and nose. The left and the right ear can't tell the difference in the time of arrival at both ears because that is such small portions of either (fractions of either wavelengths, which are 343 meters or 85.75 meters. The sound is omnidirectional. Plus, we have a difficult time hearing below 20 hz. Goggle a free frequency generator and see if you can hear 10 or 5 hz. Now imagine that with yourheadphones your eardrums are even closer to the sound source. If the tones are being played real quickly in time after each other, there is no way you can the difference in them, and probably not even if they are slightly different in frequency? Now when you get up 250 hz or so, that is when you can hear the difference in arrival time. Science has known this for at least 70 and maybe over 100 years.
So what is going on with these binaural beats, which you can obviously hear? They are modulating these so-called magical frequencies with much higher audible frequencies, say 100 hz or 400 hz, and this gives a little difference in each ear because the lower frequencies intermodulate, or beat, with the higher frequencies. A 400 hz tone added to a 5 hz tone will give you side frequencies of 395 hz and 405 hz plus other lesser in loudness than that. That is what binaura beats are. And people who produce them often buy programs that produce them. I have hear a couple of very imaginative, complex, and creative instances of these, which are almost like compositions and are very soothing like any good music. I believe she is a creator from the UK, and her creations sound like she is creating her own tone and beats. But the vast majority of them and binaural beats about kundalini rising, Chakras, and so on, and they tout magical benefits. I don't see how any double-blind tests can be done because the user will always know when the headphones are on and the earphones are in, and that raises the placebo effect. If people anticipate something good might be going on, they might pay better attention or relax, as you alluded to, Vanessa.
However, all is not lost. Calm is an App, that provides various tones in in a manner that purports to have scientific research behind it. In the advertisement which I viewed, it demonstrated and talked about applying tones, not binaural beats to the left and then the right prefrontal lobes, it could be hemispheres (I hope my terminology is correct). Plus it goes outside the ears a little to the front. The assertion is that leisurely alternating left and right has been scientifically show to relax people. I can't really vouch for it, but it does seem to be a more scientific approach.
End of Part 1
But there is more that is very real, and you mentioned it in your last video--ASMR. But it's not ASMR, but where ASMR started--right here on RUclips. ASMR did not come from ASMR, at least as far as I know. It came from binaural sound, sometimes called 3D sound. And it started from one specific binaural sound demonstration. I'll try to pull the video up and link it, so I'll have to post and then edit. It's called Virtual Barber Shop. Okay, here is the link: m.ruclips.net/video/IUDTlvagjJA/видео.html This is what started ASMR. I didn't know it at the time. I was away from RUclips for some years. Then I came back and ASMR was all over the place, and Braincraft, and some other interesting content.
Binaural audio is what I have the most experience with in regards to this presentation by Vanessa. Binaural audio is where you place microphones, usually small and usually inside a dummy heads ear canals to record audio that sound incredibly spacious and lifelike. If you have ever hear an ASMR using a 3Dio microphone, that is a form of binaural audio. For me, audio using binaural audio is the most enjoyable. You can also get Dolby Headphone or DTX as apps for the pc and, I assume, Appl, and I forgot, Spatial Audio.. They have much the same effect using software. The University of Sydney (edit, oops) ,at least I believe that's the correct Australian university, has an anechoic chamber, purported to be one of the quietest places on earth, where some 3d sound research has been done. Happy listening.
Sorry if the are some typos. I typed this on my tablet.
