It seems like Mendi works like a pedometer for your brain, measuring blood flow to your frontal cortex during concentration tasks, such as tracking a moving ball. While Mendi can motivate cognitive engagement, the real benefits come from the activities themselves. To boost blood flow to your frontal cortex, engage in mentally stimulating tasks like playing chess, drawing, or using a simple app. Essentially, you don't need Mendi, just as you don't need a pedometer to benefit from walking.

@CodyRallMD So i suppose that an experienced meditator could achieve easily 90-100 score, the first time using mendi without playing the game, just focusing in meditation, isn't it? Can this be proved?

@AnotherCoyote 2 ай бұрын

You'll know it REALLY works if you can achieve a Jhana state during meditation with it, which is an altered state of consciousness much like an out of body experience. I've experienced one of these so far and would love to find a brain computer interface that helps me get back to achieving these states again.

@avatar1867 Ай бұрын

I would suspect research grade equipment with this would work. I would love to have the "ball" that moves up hill when a pattern of brainwaves emerges. This way I could record, find, set certain patterns and play the game with those patters or types of activity.

I’m so sorry you and your son are going through this. It is truly gut-wrenching to read! I don’t know if it’s feasible but I would suggest looking into equitherapy or equine-therapy for your son. I had a friend who had a massive brain aneurysm and I brought him to equitherapy all summer and he improved dramatically! I saw all kinds of people there with varying injuries and/or emotional issues improve. Horses don’t judge! This was just the thought that jumped into my head while reading your post. Prayers for you and your precious son! BTW, my son and I are trying out the Mendi headband for ADHD. Too soon to tell.

Muse gave 95 percent calm. I thought it might be fluke so again yesterday and 3 times today I did the same and with the same result (89-95%) calm along with tingling sensation.

I'd like to see similar tests for other groups that have diminished cerebral blood flow and HRV. Patients with ME/POTS/Long Covid would be interesting to study. In such groups concentration falls post exertion and even when just standing in the case of POTS. Using the Mendi with Long Covid confirmed to me there's a big difference in prefrontal blood flow after exercise.

@excel04 6 күн бұрын

@@ajsanchez-o7i for me, not yet. I found it helped when I modified my approach and ignored the ball game and wore the Mendi whilst doing Qi Gong. I got good scores but I was more focused on calming my internal physiological processes than an exterior video game simulation. Calming the nervous system out of fight or flight is key. What has helped Long Covid is IHE (intermittent hypoxia exposure or altitude training), red light, methylene blue, ozone therapy, breathworks and psychological support. If you're poorly I wish you well.

I'm not sure how tracking blood flow does anything to improve it. The claim is that by focusing on the game and practicing with it allows the user to willfully increase the blood flow. I say, prove it. I don't mean studies that are conducted to reinforce the product. I mean show me the before an after metrics of someone working in a distracting environment and the level of focus they have after months of use. This study would have to be performed without the subject's knowledge of the metrics you are measuring. If you tell them it's to help their ADHD, then they are likely to experience a placebo effect. I'm sure this is something that is corrupting the results of these so-called "studies".

@slmille4 4 ай бұрын

One problem with the cognitive load study is that it's the DLPFC which is associated with cognitive load and working memory. The MPFC, which Mendi measures, is associated with adding motivational and emotional context, making certain tasks more engaging or prioritized. These are related, which is why there was some effect for the working memory study, but also might explain why the Mendi showed a larger response for 1 Tetris game on 1 iPad, than 3. 1 iPad would involve deeper focus, while 3 would involve more cognitive load.

@pelletey 4 ай бұрын

yes, the areas being measured are used for different functions. ILF/SCP EEG could be a good cheaper alternative to fNIRS where the DC field changes also correspond to overall activity changes in the brain. If classical EEG neurofeedback is used it is a bit questionable as to how the increase in activity will be measured.

I would think the Muse. Mendi takes a lot of work to see results and this is going to frustrate a lot of users who are not willing to commit. I think Muse will give you the want to continue using it and also if you were to get the muse s then you would have the ability to track your sleep. So, in ending the think Muse first, Mendi as you get more advanced.

So Mendi can track the blood Flow. But Still It doesn't do anything. It Just measures if you are concentrating. The Mandy app game is very boring. So why not concentrate on something else like reading a book och playing a fun computer game. It's not Mendi Who does anything to your brain it just measure is it. The game is so very boring I Used it for three weeks then I quit totally pointless in my opinion

@CodyRallMD 4 ай бұрын

I mean, ideally the game is not supposed to entertain you but I can see what you are saying. I know they are adding more and more features for more variable training. That's why I like to use it as a primer to more mental training, rather than the entire mental exercise for my morning routine.

@johnconnolly512 4 ай бұрын

With respect, I think that you are missing the point. Mendi is a simple tool, but the basic idea behind all biofeedback is to visualize (or sonify) normally unconscious phenomena such as autonomic arousal, and allow the user to learn to associate subjective states and sensations with desired target states. As they train, this gives them a degree of volitional control over formerly unmanageable aspects of themselves. As far as Mendi is concerned, a lot of people with concentration issues don't really know what it feels like to be in a state of relaxed concentration and a tool that allows them to visualize this state, and then eventually learn how to self-induce it, could be quite useful. If you already know how to concentrate properly, I can see it being a bit less compelling.

@gimmeadollr 4 ай бұрын

Adding on to John's answer, I went into Mendi believing that focusing meant pushing harder with my mind, like the mental version of squeezing my hand as hard as possible. The Mendi game responded best when I was "squeezing" somewhere between as forcefully as possible and as relaxed as possible, and not just anywhere in between. It helps me identify that sweet spot.
