Excellent - thank you for reviewing!

Ive been using Mendi for a few weeks now. Originally just got it to improve my adhd issues. Since Ive been using it, Ive noticed patterns in my thinking during the sessions that are related to some of my mental health issues. My thought patterns have become a bit easier to manage since I started. I typically do four of the five minute sessions per week, but I felt enough confidence to do a 10 min session today! Im feeling pretty excited about this thing right now! Im really grateful these guys have put this thing together!

Thank you a lot !

Dr. Roll, Did you receive any compensation for this or the more recent Mendi video?

I will buy this! Thanks for the review. Will come back with my results.

your link still works. im going to order it.

I'll be keeping my eye in this product. And when they make the improvements you suggest, I'll think about getting one. Right now, my Muse S is doing the job.

I'm buying one of these to mostly use as it is intended but also to experiment with. Also, I do a slightly modified wim hof breathing exercise every morning and my main objective when holding my breath is to maintain focus on the light that I usually see. i've been doing this for a while and have begun to be able to feel my heart beat in my forehead but as I hold my breath after exhale it becomes harder and harder to maintain that focus and to keep my eyes closed. Interestingly I noticed I could hold my breath much longer, on both exhale and inhale, when focusing on something like that light or the heart beat than if I just sit there. So maybe an objective for this device as it relates to wim hof would be to decrease the size of the drop in oxygen levels when holding the breath and maybe at an advanced level even maintain the high oxygen levels

Hi Dr. Cody, thanks very much for Mendi Review. It would be great if you can cover the comparison between Mendi and FocusCalm some time soon.

I appt all of the honest feedback you are sharing. I didn’t see a link from you to purchase. Wondering if you are going to do a video comparing mendi & focus calm?

Can you review the Vielight? Also discuss neurowearables for thought disorganization like in schizophrenia?

Some in-depth review with hints how to improve results will be help-full. It was interesting video thanx !

I also had my wife purchase one for herself she's dealing with PTSD from a very young child age and she's also getting counseling therapy but only computers can do what computers can do so seeing what the brain is doing it's an incredible thing it takes all the guesswork out then the computer already knows what it needs to do when it sees things out of whack it's not your mind it's your brain this is definitely high-tech science for the human race

Hey Cody, working with the Mendi on your suggestion. And, since you have an inside connection there, maybe talk to them about their support. Many people chatting online about not getting replies after weeks of trying. They have a reddit, too, and nobody seems to respond there either often. I know they have a FB but not everyone cares to be in the Zuck universe so at least email support should be more efficient. OTOH, keep up your good work.

Thanks for the review!! I am really interested in purchasing. Just wondering if we should be concerned about radiation since this is a wireless device? I never put my cell against my head for this reason, use speaker phone most of the time.

This is just to give you a big hug. I have had to step away from neurohacking for a couple of years due to needing to heal some very old childhood trauma that I was only vaguely aware of. I'm still in the trenches here but like the story of being stuck down a hole & asking for help from a doctor (prescription) & a priest (prayer) I've been down here before so it's only a matter of when I get out! So it's good to see you have been covering this field & as soon as I get capable of reliably using my muse etc I will be back at it again. Sadly according to recent videos that some of the tech I have bought to help me you do not have good opinions of but I guess that's a risk you take at the leading edge! If hadn't been you my life could have been a lot worse. So this is just to give you as a big hugs & I hope to be back more in the future

My Mendi just came in yesterday and it’s cool. Still very confused on how to make the ball move so any advice on this would be great!

Can someone explain to me, why there were uptrends in blood flow over time for EVERY situation tested? Surely the trend for a nap would be a DOWN trend over the 5 minutes? As frontal lobe activity decreases? And tracking blood flow on his leg while NOT moving the leg, can anyone explain why the blood flow increased slowly over the 5 minutes from him just sitting there? I was expecting a flat graph for that.

I love mendi and use it everyday! I've noticed, when doing the eco meditation before from dawson church that transforms your brain completely, I have a 5-8 fold better outcome. It's part of my morning routine to do 20min Eco meditation, and then 10min Mendi. My record is 87% with 16,843p (10min)

Thanks Doc thanks for the response wow I just did a Mendy session and I've been taking really good notes all through my training I have a training background in different arenas and so today's training it literally wore me out I was able to do a focusing session that literally I'm starting to come back from now 10 minutes after 15 minutes after but wow when you really start learning how to work that muscle wow I don't want to tell you my numbers because those are my numbers and everybody's numbers are different and everybody's work is different and the Mendy is doing incredible things individually very specifically it takes calculations and then it tweaks the program to strengthen you in the categories that need to be strengthened and from what I have learned if I'm not mistaken doc The Mindy the AI is constantly tweaking what it does so that it strengthens the areas that it is focusing on at the beginning of the session before it starts it does a calculation and from what I've read and learned it's always doing calculations and what your mind does what your brain does and it monitors all that to adjust the program to tighten up the things that are less tight in the brain so it changes what it looks at and focuses on to tighten up in your brain and so your numbers are always going to be a bit different they can be the same but they may be totally different because of what the computer software is doing to strengthen up the brain it's like sort of like tuning in a guitar you tune in certain parts of the guitar and then other parts of the guitar become a little Out Of Tune so you go over and you tune up those strings and so you have to find the tuning and that's what the Mandy does it turns your brain to be in tune the more you tune it with the MENDI. the more in tune it will be what do you think of that analogy doc

i got to find your vid you did on how to use it for beginners.

Did the light issue get resolved yet?

Hey Dr. Cody! Love your content (AND this thumbnail is intense) QUESTION: I really want to be able to measure my meditations. Specifically when I’m in coherent alpha/theta/gamma brain waves. You’re an expert in this field. Can you tell me if the Muse can do this??

does it have live audio feedback so i can use it while meditating and checking if i can keep my attention in front?

@Dr. Cody - Muse, Neurosity, Focus Calm, iSyncwave or now Mendi? It would really help if there was a side by side comparison table that showed not just technical aspects, but clinical physical benefits.

Are there any third party apps like what mind monitor is to the muse headband? Is there any practical use for the raw data of fnirs devices?

Great video, as usual. Helped me a lot to figure out how Medni actuakky works.

Hi Dr. Cody, thank you for your great channel and reviews... Is there a way that I can have the data from Mendi on my laptop (work under windows)?

Second! Thanks for the great video!

What is your opinion about using neuro feedback on FTD patients?

What's your thoughts on the beddr sleep tuner?

Hi Dr. Cody just wondering if one was training, lets say for a marathon and they start using this product when they cannot run a mile and then use it again 12 months later after a strict training regimen.... would there be, potentially a large change due to the (assume this a fact) increased health of their cardiovascular system and weight loss?

Still not sure. Does it measure blood flow only or gives you exercises to increase it?

Is it good if the ball keeps going up?

You are the only KZfaqr who has done a review of this product. Since you seem to have financial relations with mendi it is hard to decide whether your review is objective or not.

I'm wondering if Mendi use and training would improve sleep.

Greetings, Dr. Rall I'm interested in "Mind Monitor", but it seems that Realtime Neurofeedback for Meditation would be hindered by looking at Waveforms and .CSV, since the voltages produced are higher with your eyes CLOSED. By this reasoning, Sound would be better. For MY purpose, the ideal Program, SO simple, would be individual Musical Notes which vary, in volume, with the Voltages of the alpha, theta, beta, etc., Wavebands. Does such a program exist?

My sister just sent me a Mindy for my son I'm highly excited for the possibilities for my son

Hello Is this device ok to use by a dementia/Alzheimer’s patient? If so, how could it help? Thanks, Dalia Gonzalez

Hi Dr. Cody, thank you for your review. A question I had was how do you think this compares with meditating on one's breathing for 30 minutes a day? Is there really any advantage in your opinion? Thanks again.

Why not use with with Muse? I dont get it. That was the best way to validate the findings, gamma should be up if blood flow is increasesd.

I’m curious if you’ve noticed any practical improvement in your life over time. I haven’t found much info on this anywhere other than on the actual company website and I’d like to see some kind of unbiased testimonial to it’s actual effectiveness for improving focus, sleep, emotional stability… etc. Increasing the score with the ball is one thing, but have you noticed any differences in your life and well-being?

Is there any data showing how useful this is for ADHD and executive function issues?

Would this harm the pineal gland? A red light pointed at my pineal gland kinda freaks me out. I already avoid fluoridated water bc of the pineal gland calcification

will this work for memory ?

Hi! I´ve been trying a lot of different things to calm my nervous system(PTSD) and trying to calm my mind. I`m now trying to find a device to help my mind calm down and help with sleep, do you have any favourite or which would be better Mendi or Neorhytm?

How does this compare to an HEG? I have an HEG with the neurofeedback package I have. Thank you

Are any of the wearables currently on the market high enough quality for remote patient monitoring?

Hello Cody, Did you test the Mendi with the roxiva ?

Would like to get one...but it feels like the moment when a version 2 may be just around the corner? Hmm... 😜

I love my Mendi except 15 minutes maximum is not working well with meditation and I WANT MY DATA to use for better insights. It is my brain, after all.

Is an internet connection needed in order to use this device?

Would you recommend mendi over muse s (with Myndlift) for adhd and anxiety? Also do I need premium subscription with muse to use Myndlift?

Hey doctor I had my sister purchase this one for my son and I had my wife purchase one because I saw your KZfaq website but I don't think I heard the 10% off if I purchase a third one and we can link them all together as far as purchases that I actually purchased two before and this one to make three can I get some kind of a discount on the third one

Hi Cody, I love your reviews are always very complete! I have been wanting to buy a Mendi but I ahve a question? How many times a week do you need to use the device to see any benefits? Also, I want to share the device with my parents but I cannot use their cellphone to install the app to create different users, because they have very old phones. Could I recalibrate each time I start a session with a new "user" in order to lend the Mendi to my parents? Thank you for your help!

I'm willing to try it as an affiliate

CAN SOMEONE PLEASE EXPLAIN DOES MENDI ONLY MEASURE THE PREFRONTAL CORTEX OR DOES THE SAME AS MUSE? EVERYONE KEEPS TALKING ABOUT THE MENDI IS JUST FOR FOCUS NOT HELPJNG IT STSY CALM??

Are they sending to israel? i didnt see in their sit posiiblity shipping to israek

Is mendi dead? I dont see any firmware or app updates

anything that can help with my ADHD?

Do you need to pay a subscription?

Even after using it for a few weeks I’m still a little unclear of the “proper” mental technique used to influence the ball. Are you thinking “up up up” as if you were trying to Jedi push it? Other times I’ve tried repeatedly trying to be present and hyper focused on the ball, and returning when I’ve been distracted. And I’ve tried other methods…. I wish there was clear instruction on what you need to do for optimal improvements

8:20 so the same wavelength as sunlight, but how powerful ...... or are we saying that sunlight shines into my frontal lobe ? Focus is attention but for longer. Unfortunately a lot of energy is needed for that and that is probably why we need rest between high intensity attention or log time focus requiring activity. I have brain fog and it's probably the lack of energy. Also new research on red blood cells not being able to take the oxygen to the cells. No attention because of too much stimulus is a different problem. Also if you get more blood to that area, the chances are it will grow or the blood vessels will grow in trying to adjust, now your head needs to get more blood or it might starves other area?!

@14:00 Awww Snap! Don't tell me that I spent $300 on the NeoRhythm for less effect on my brain than a NAP!!!

What eeg product has the most accurate data.

Hey, thanks for your content. Its been inspiring. I´d like to ask you if you know of anyone working on merging neurofeedback devices that incorporate AI-based coaching, looking to provide guidance and support to people improve our cognitive function or manage symptoms of mental health conditions, etc

does this thing actually do anything of value or are they sponsoring your videos? I can't find any good information or experiences on the device except from your channel.. just trying to get information

Hello I'm from India how to purchase mendi and what's the price in India rupees can please help me

How can it mesure bloodflow through you skull? It makes no sense to me

Does this work to ADHD patients?

Does it make you more biased if you have a promotion link in the description - I thought that idea of the channel is "Scientific reviews"? And don't you need to disclose that you are getting paid for that type of review?

Maybe v2.0 would be something worth spending money on.

The Mendi feedback when using the Neorythm isn’t what you would hope.

I would rather take a modafinil

ADHA REAL BAD DOES THIS HELP

I have tried Mendi and found it not usable at all. The app where you suppose to train your brain and control the ball is just a joke.

When I see an affiliate link for the very product being reviewed, the review loses all credibility….

Just bought this. I’m a sleep doc. And subscribed. Like the channel. Thanks for the “heads up” on the light. But wondering if you wore a baseball cap. EEG: when I teach students about EEG and fellows in sleep. This is my analogy, imagine you are at a a stadium packed with 84,000 people. I lower a microphone down into the center of the field. I want to find a specific person shouting from that position. Almost impossible, BUT I can tell when the crowd is a doing “a wave “ and if I know where the wave started I can approximate the location in the stadium not by seat or row but by section if we are lucky.

actually sorry

That head band is total scam. Maybe idea behind it is great, probably is. But you’ll get same results starring at the apple for 5 minutes. I just put Mendi over a pillow and app did all the up and downs and give bunch of stars. On the freaking pillow

This is a long promotion; it’s ok to make money from promotion. But at least don’t try to pretend it’s to be true or real just because you have a YT account with followers. Have some responsibilities. These people are vulnerable having a mental disorder and you are just after their money taking advantage of their situation promoting various new products everyday. It’s cruel.

It sounds like you proved that playing guitar is 100 times better for your brain then sitting with this device? How is this device useful? Maybe if you track your blood flow all day every day for a week, and you can see when your brain has peak energy, then that is when you should do your studying.
