"That study raised a few eyebrows..." Guess they had the electrodes in the wrong place.
LOL. Liked this smartass comment.
Lame joke m8
Nice joke
That's methed up bruh
Struggled with severe anxiety since I was about 6, completely inhibited my life, yeah, so this works immediately. No need to have a sceptical voice and try to debunk it, I am a living example - it works, it is a life changer.
RIGHT? It’s ALL about money!!
2:34 "One study in 2016, used a cadaver to measure how much current..."
And the name of this doctor who applied electricity to dead bodies: Victor Frankenstein.
Shhhh igor.
turn on the svitch!
He tried it out on the brain of a fellow named Abby. What could go wrong?
CAPSLOCKPUNDIT Wait, Abby... Abby Normal?
Don't forget the sed-a-give! :o)
Positive electrodes boost neural function. And inserting a stick of DDR3 RAM into my skull will improve my memory.
Well the latter is true
Combat King 0
Just one stick?
You need two of your brain won't boot properly :P
but how do I download a stick of RAM?
One stick goes in through each nostril. Once you hear a click, the RAM has seated properly and you can go ahead and restart. Simple.
plebs, use ddr5 for faster and better memory!
The US Army is using this to increase the performance of combat soldiers. The Airforce also uses it for pilots. It works extremely well.
How helps? Like increasing performance? How about chronic illness like Parkinson epilepsy neurological disorder 😉any info about it
@@altunga8849 MIT posted a study a few days ago about improving short term memory. I know the concept of plaques causing Alzheimer's is now changing. Not sure if there is any legit medication ready for market now
@@davidhasselhoff619 what about Parkinson disease treatment
Why isn't this being studied more rigorously? As inexpensive as the actual treatment is, any potential benefit, however small, should be worth the research, shouldn't it?
Government is conspiracy is why. Military has no problem studying it quietly.
selling medicine is more profitable
Actually, it is being studied by Mayo Clinic. However, no conclusions have been reached yet.
Ethical reasons. Dont want permanent damage to people, and it’s hard to test it on animals.

No mention of TMS (Transcranial Magnetic Stimulation)?? Differences between tDCS and TMS?? Same/similar effects?? Would love to see a vid about this as well. Thanks SciShow!!
From a consultation, TMS is more like an MRI than ECT. It uses magnetism to create a current.
YES! I've been waiting for them to do TMS! I did it and it successfully gave me remission from depression, and it's much more scientifically proven then tDCS. It's FDA approved and it literally saves lives! I'm always trying to spread the word about because not many people know that it exists.
And for the other commentor, yes, it is kind of like MRIs, except instead of just scanning your brain, it actually sends magnetic pulses, treating the brain for various things. And you don't have to go in a giant tube to do TMS, unlike MRI scans.
The "OMNI stimulator" is the least expensive. Less than a hundred. I've been using one DAILY for 8 months now to treat depression. I'm off meds and I feel NORMAL. It works for me.
As an engineer student this issue makes me cringe so hard. If companies can't define exactly how it helps someone, what region of the brain it is working, how it is working and what are the exact effects and downsides of this "treatment" it is not science. If it's just a bunch of people that released "a study" that says it might work, without pointing out the exact nature of it, it is just as valid as putting a bible under someone's pillow to avoid demons from giving a child's nightmares. Because someone said it works, not because of how it works. Humans are very complicated subjects, and we adults need to be more responsible about these stuff.
its just greedy companies in capitalist countries that try to make money off people who cant see or think about things any further than what's advertised
Nice comment
Well, welcome to the world of psychology! You know that how and why almost all psychiatric medication works exactly still is a mystery right?
That's psychology, unfortunately! Though the statistics give us an idea of how likely an effect is to be chance, knowledge about mechanisms is hard won. Hell, we don't even know how paracetamol works yet.

I remember making a tDCS device after I saw an episode of through the wormhole with Morgan Freeman back in late 2012. In the episode the technique was being tested for military application, and was showing that people under stimulation were significantly cutting learning curbs. They were performing at almost the same level as those that were experienced without having all the practice hours. I was trying to increase the activity in the right prefrontal lobe, and used it only a couple of times. I decided that the whole thing was still premature and I'd be better off waiting for proven research before I continued.
Will this give you super intelligence?
hey wassup what do you think about tDCS now?
making? how did you make one?
Psychology video on why sports superstitions are so common please!
Neuro-therapy, of which tDCS is just one application (or "modality"), is still in its infancy, but it is understood well enough to be useful if its application is being guided by a certified therapist. Sure, you can try it on your own, but that's like using a shotgun while you're blindfolded. The odds of obtaining the results you're looking for are pretty slim, and you may make yourself worse instead of better. I have kidney disease, I've been through dialysis, and now have a kidney transplant. I had read that kidney disease causes "cognitive degradation," but that's too vague of a description to be useful. What I did know was that over a 5-year period my kidney disease took me from being a competent aerospace engineer to making me worry that I was getting dementia. I could no longer function as an engineer. I saw a competent neuro-therapist. Three months later I had my much of my engineer mojo back. Even my boss saw the difference it made. My neuro-therapist began with giving me an EEG. The EEG revealed what part of my brain functions had been degraded, which knowledge she then used to tailor my therapy to correcting my brain function. You can't just go at it haphazardly and get the benefit you're looking for.
@@Darenz-cg9zg I had the same boss for about 10 years. he knew the good work I was capable of, and was patient while I worked my way through my health issues. Not every boss would have done that, but he did. Golden.
You tried so hard to debunk this that I know it has to work!
Randomly messing with your brain, without knowing what it does. What could possibly go wrong?
matthe ai LMAO right
It works.. CES is less invasive.. but tdcs has also worked. I am off ssri's and thought I never would
interesting...which one has been more effective for you?
That's good to hear! How often do you do tdcs a day? As someone on ssri's myself (switched from daily kratom use to help anxiety) rn 😪 this would be great 👍 I also use L Tyrosine and notice it helps quite a bit

Yeah... it is not a scam.
These damn closed minded internet morons!
How is such a small current even getting to the brain? Would it take the path of least resistance and just travel through the skin? I imagine that bone isn't very conductive.
while the path of least resistance is a good rule of thumb it isn't actually true. Electricity travels through all paths however how the current is divided between them is inversly proportional to the amount of resistance each path has.
bone is probably more conductive than skin with the amount of fat in it
...Not to mention the [conductive] saline content of bodily fluids, in all tissues including bone.
I'm looking into getting TMS therapy for severe deppression. It would be awesome if you guys could do a video on it. If it's anywhere near as effective as claimed it could completely change lives for people like me who have no choice but to suffer from and medicate severe clinical deppression
It's effective. Studied it in psychology classes in college.
I do remember a study where humans were turned into human calculators using magnetic fields.
find it and put the link.
@@ras573 Do a TH-cam search for "Roi Cohen Kadosh," he gives a Ted talk about his research. He speaks rather slowly, so speeding the audio up to 1.25 would help. (On cellphone; copying the link won't work).
I've had them. ElectroConvulsive Therapy. 14 in total. It was because of the psychosis I suffered from. It has probably been two years and I can say that I feel good now. I lost an immense amount of experience in skiing and my first time on a hoaverboard was like I had the legs of a lamb. But it has all been for a greater goal.
Ruben Aders You may want to check out TMS (Transcranial Magnetic Stimulation) instead. I don't know exactly what you were treating when you underwent ECT, but TMS is painless (minus maybe a headache) and there no anesthesia or hospitalization. You can drive yourself to and from treatment and be active afterwards as much as you want. Plus, it doesn't have the side effects normally discussed with ECT, such as memory loss. They're still learning what TMS can treat, but so far it can treat depression, anxiety, PTSD (if I remember correctly), etc.
you guys dont know what you are talking about. taping a aaa battery to my forehead has raised my iq by 60%. everywhere i go people are intimidated because of my superior intelligence.
Daniel90mm I don't believe you due to your improper sentences.

sausage4mash has a run on sentence.
+sausage4mash I misread neck ache as neck acne. Just thought you'd like to know.
Daniel90mm Damn! You're IQ is near good enough to understand Rick and Morty.
Can you do an updated video on this please? I’m now using the Flow Neuroscience headset to treat my treatment resistant depression and I’ve actually seen really good results despite having low expectations going into it. I’d love to see what newer research says.
So I've just completed a three-week session of tdcs at Johns Hopkins Hospital in Baltimore. I'm being treated for a traumatic brain injury affecting my left leg. I am much better at discharge then when I went in.
@HiddenLeafShinobi I’m not surprised . This is just one of the many channels that has fallen victim to the culture of layman shaming, gaslighting, and humiliation.
These channels don’t want you to have a contrarian opinion to what is being embraced by the media of people who think they represent the voice of science.
Their default will always be to passive aggressively humiliate people for thinking outside the box or having a contrarian opinion.
Their arguments, often times, are that people are stupid for thinking x, y, z, and here is how all you dumb adults are trying to kill yourselves.
It’s depressing. I watch this content very sparingly because it makes me loathe what the medical industry has done to the minds of the people in the US. We don’t have freedom of scientific exploration, and we’re going back to the dark ages in terms of making science into something that is self-correcting.
I wish there were some place people like you could speak so we could hear from real people. If you find one, let me know.
Love your videos SciShow Psych! Keep up the great work!
Oh boy, I can't wait for more videos from this channel, a new one every twice a week!
I hope one day we will be able to stimulate our brains in any way we desire. I would love to temporarily experience the worst pain without any physical consequence for the body.
Bro that'd be awesome, ive always wondered if Id be able to handle that
Question: is this the same as TMS treatment (transcranial magnetic stimulation)? I’m getting that done right now and it seems more intense than this. Would you ever maybe do a video on TMS? I’d love to hear your perspective on it!
It's not the same, but I'm sure you already got it in the last 7 months.
Btw, I'm just curious. What did they use it for, and what were the effects?
all this video did was give me an idea for the next big jumpscare style horror flick involving tDCS and ghosts trying to drag the protagonist through the mouth of hell.
AnimeShinigami13 I like how you think, my friend.
Can we have an update on this video now that it is 5 years later. We should know more about if this really works or not
Ah, the wonderful world of unregulated health claims.
andrew zuo Copper bracelets, anyone?
BigBen Hebdomadarius could use some more cowbell.
BigBen Hebdomadarius Sure, thanks, but only if there's an iron one for my other wrist.
See books.google.com.au/books?id=8iIlDwAAQBAJ&printsec=frontcover#v=onepage&q&f=false
So we should only accept "regulated" health claims ? Tcdcs devices can be bought for less than $100. This cost is equivalent to 5 weeks supply of anti-depressant medications, most of which show a superiority of only 10-20% above placebo. Individuals can use tcdcs at home & instructions are readily available. If it works - you've got your life back. If it doesn't work - you've lost some small change.
Meeeh, something tells me blasting electric currents through you brain on your own ain't that bright of an idea in the first place.
I'm quite skeptical, but plenty of advances have occurred from people doing not-so-bright-idea activities. Wanna go fly a kite in a thunderstorm? :)
I'm a bit wary of doing anything to my brain that isn't clinically proven...
You mean like the alcohol, trans fats and fluoride you all don't mind consuming?
You might want to actually do some research instead of trusting your typical fake science ridicule program ;-) The current is less than 2 MILIamps.
I wouldn't shock my brain like this without knowing its effects...
I'm using one right now and it's helping me.
A few years back, saw a counselor who let me try something like a tDCS for a few sessions, only his used a very low voltage, high frequency, alternating current, and the contacts were clipped on to the earlobes. It SEEMED like I got substantially better sleep quality the night of the treatment - but that may have well been wishful thinking.
just thinking about this made me feel tingling in my head
i actually did tdcs to myself using a homemade device. i used 2 ma to 3 ma. i had acne at the time and it stung. i cant really say it worked. i did it while doing 30 min language learning exercises and it didnt seem to make it easier. it may have even been worse because the slight sting and all the wires were very distracting

can the Placebo effect help with depression
Gary Marrufo to an extend yes, it really is depend on the cause and how severe the depression is
no scishow pysch actually has a vid on this
Only if you think it can.
4:57 - "Hey folks, our conclusion is simply this: Touch a nine volt battery to your tongue instead, and give the rest of your money to us."
* I love SciShow, and I support this agenda! *
Are you saying I should stop running house current through my brain? Next you'll be saying that self trepanation is a bad thing as well.
This is super exciting to me as a stroke survivor. Being able to possibly regain back usable motor function in my left arm/hand would be amazing.
It makes sense that only 90% (or whatever) gets through. That implies a lot of energy is being USED in some way, expended. Like when you power a light bulb or computer, less than 100% of the electricity it draws is feee to use for something else afterward. JFC what a daft thing to propose as a flaw.
There's something like this being "sold" as a way to help fibromyalgia sufferers. I looked into it. Costs a hell of a lot and the idea of having some random person sticking electrodes on my head and sending electricity through it made me think I'd rather put up with the pain. lol
What a *SHOCKING* video, this really *STRUCK* me
rarest pepe but it's a bright idea isn't it? Currently I'd like to try it
A HUGE bolt of wisdom.. Eureka!! XD
After Faraday discovered electricity, people in the 19th century fell for the same sort of hype & wasted money on machines that also zapped you!
It is not strong enough to go INTO the head, it is called trans cranial, and therefore goes across the scalp. However, in acupuncture there is lots of evidence of brain function change with needles, so it may cause some change with electrical stimulation. Must really consider placebo and other issues.
That 2016 study with the cadaver doesn't seem like the controversial hottake it was supposed to be. Without the active ebb and flow of living neurons it makes sense that small mA wouldn't get through the skull as the low mA is meant to influence neuronal activity and not outright force performance. The Air Force studies demonstrating increased myelinatiin seem more significant than a cadaver study.
I have found tdcs to be very helpful with depression. Much better than medication. Just my experience.
Hi iam also suffering with depression
Sounds like Dr. Lous Holter's "Electrical Chair" in Garrison Keillor's book "Lake Wobegon Days."
_"Rather then spend your money on something stupid, why not give it to us?"_
Subtle. xD
Brought to you by the people who provide copper bracelets that will cure your arthritis . . . .
That's an old wives tail, this is an actual technology that has support from different organisations, including the U.S.A.F.
Actually, if you think it works, there's a good chance that it will.
I have been using a TCDC device of my own making for about six years. It certainly has boosted my cognitive abilities. I use a basic small volume control to address controlling the intensity. As a side note, I would add that it seems to actually help with manifesting things. In other words, they say that your thoughts have power. In my case, I give more power to my thoughts. Whether it's related to the documented effect that thoughts seem to have at the Quantum level of reality or not, my attainment of things that I want to bring into my life seems to be related to the use of TCDS. Consider that possibility. Prayer, meditation, etc. all brought up to another level with the addition of more power...So, be careful what you wish for.
That's crazy!
Can't wait to try it
Were you actively trying to do it or you just noticed these effects passively?
If you change the membrane potentials of neurons to make them fire easier, that's actually a serious problem. That's exactly the type of thing that causes seizures--the threshold for signal propagation being too low so you end up causing a sort of positive-feedback electrical storm.
That's also how therapeutic marijuana for seizures works; it dampens neuron signal propagation so the rolling signal waves of seizures can't get rolling.
The unit I have if you pick up the cathode and place it back down semi quickly you will see a flash of light. Also you will get a taste in your mouth as if it was full of copper pennies.
Loved this from years ago. Any chance there are new updates?
There are already two proven methods to boost the performance and health of your brain:
Changing your diet and exercising, preferably outside.
And as a nice side effect: the rest of your body will benefit as well.
Been doing those two for years. Sometimes it’s not enough
Isn't caffeine much more effective?
I'm really curious about the depression applications 🤔
Go read some actual information instead of listening to these typical phony "science" debunkers. These devices have helped alot of people with PTSD, and stroke paralyzed people. The ridicule is sponsored by big pharma. They want you on toxic drugs instead of extremely cheap devices that actually DO help many people.Just take a look at the cancer industry. There are and have been hundreds of actual cancer cures that cost literally nothing, they want to kill you with toxic drugs and radiation before you die because this makes trillions of dollars for the death industry.
I want to stimulate my pain receptors to experience the worst pain possible without causing any damage to my body. Only to my mind.
Due to neural plasticity, it doesn't really surprise me that it has such a wide range of effects, or lack thereof. Even for conditions like depression exist for different reasons and to different levels, which is why there isn't a single medication that applies to everyone.
dont need tDCS, SciShow stimulates enough neurons for me XD
Isn't tDSC essentially what Clifford Devoe did in season 4 of The Flash?
It's been a good minute since I've seen this guy!!!!
I was medically treated with this at a headache clinic, after a severe Traumatic Brain Injury - All i ever got out of it was: sick to my stomach.
May I ask, please that you share, what, if anything you’ve tried that has helped with your TBI?
Loved hank in this. *Every - twice a week*
*Hanks kids watch his videos* "but you are my dad wtf?".
Could you trigger a high with this technology?
you, my dude, are asking all the right questions, this needs to be bumped higher, WE NEED ANSWERS !
Barnard Rabenold the paces youd have to be stimulating (brainstem and core brain) are deep inside and hard to reach, and also are right next to important stuff like breathing
of course not.
everybody would be doing it if it would trigger a high.
I wonder if the current's modulated to induce specific brain-wave patterns. If so, yeah you could get high on it [or at least cheerful and/or deeply relaxed and/or very alert, depending *which* waveforms you're modulating for].
Digital Trips?
What about the tDCS (I think it’s also called CES for cerebro electric stimulator) that have certain wavelengths (subdelta, delta, theta, gamma, etc.) Also, I saw this thing called ICES from a company from micropulse that uses strong magnetic fields instead of electricity.
just lick one of those brick bateries you put in your fire alarm if you want to shock your self safely
I do know when I grabbed an electrified fence that I suddenly clearly knew to remove myself from it.
You are indeed a genius!
The cadaver used in the study showed distinct homicidal tendencies, but a marked improvement in language utilisation. He was later trapped in a mill and burned by an angry crowd of villagers.
Nice a non lethal version of electric shock therapy XD
Thank You for the info. I was looking into this.
good job keeping your hard movements mostly in front of your body, Hank! 💚
You guys should do an episode about lucid dreaming
Funny to think how knowledge is carried throughout spacetime
Smart inclusion of the patreon note. This time it was actually tied to the subject in the video. And. Well. Got me actually thinking about helping the channel. I have a really tight budget, so i have to choose carefully what channels i give my money.
The point i was making; The tDCS has no evidence of making me/you any smarter. Though, the SciShow already has. I usually google a lot of things mid-video, i get just the pointers on what to search for from these. And, some videos have taught me a lot.
How does this stimulate the brain when the path of least resistance is across the scalp where there is soft tissue?
I've been using it and a believe it's been a game changer
th-cam.com/video/Lv1fFcrveqY/w-d-xo.html
Older Hank to his son:"Don't do that! It shown to be useless! And I'm your father!"
I was literally JUST TODAY wondering what would happen if you sent current though someone's brain (Don't ask). How handy!
Wouldn't most of the current just flow around the skull through the skin?
I'd imagine so. Cytoplasm makes for a far better conductor than bone.
There's something actually called "the skin effect"
I'd guess that's where they pointed out the figure of some 90% of the current actually NOT getting through...
Though, I'd wonder if that was precise, exactly, or just a ballpark figure... Yes, they pointed out someone generated it by electrocuting the head of a cadaver to test... But under what conditions?
My skin is considerably more conductive after sweating (salty water added)... And even between the skin and bone of the scalp, there's some subcutaneous fat and connective tissue... Granted, not much, which is why it's so easy to rip a scalp off in a single piece... but...
Most bodily fluids also have a saline content, making them better conductors than bone or probably brain tissue...
Somehow, this whole process seems dubious at best. :o)
I think the idea is that however much does get through is 'enough', as, at least on dead people, studies to show that *some* gets through.
It "MIGHT"
So now how can we know if it's not placebo?
And then it's the use benefits where one says it amps or sedates or treats ... Idk
There have been placebo controlled studies with a tCDS device also tested by the NHS in the UK and reports are that it is helpful in may cases at reducing depression.
"every.....um twice a week"
"shut up and take my money! "
I have a tDCS unit that I've used a handful of times, it's an interesting experience
Well I'm intrigued to see what becomes of this, but I'm definitely not going to be messing around with this. I'd rather not mess up my brain further.
I think you should be careful with making your neurons fire more as this is pretty much what happens in the brains of epileptic and schizophrenic people.
5 years later.. airforce lab is even training pilot brains , to learn more in shorter time. so does it work or not ?
We love you HANK!
it sounds like the current will stay mostly on the skin, where coincidentally your hair follicles are. maybe it can help with male pattern baldness by stimulating them?
...This is like the old weight loss belt. Instead of becoming a jock without working out, it's becoming a nerd without studying.
I saw an episode of Through the Wormhole with Morgan Freeman about this. They actually used the device and showed how and why it works. No need to speculate when you can do the research.
SO WHAT IF THEY PUT IT IN THE MIDDLE PART? Since in life everything requires balance like neutral positive and negative, what if they put it in the middle the place between the hemispheres, Im sure many other things may show up for further studies
But what about habituation? And wouldn't discontinued use lead to a drop in normal electrochemical activity?
It sounds sort of similar to the idea behind rTMS treatment except rTMS is done by professionals and has evidence behind it.
This feels a lot more like the YIAY comment section than a SciShow comment section
Lol, I saw this and was like, "oh this is why they used the shock chair back then"
Ooh! Overvolting and overclocking a brain!
