This noninvasive treatment, which works by inducing brain waves known as gamma oscillations, also greatly reduced the number of amyloid plaques found in the brains of these mice. Anyone who is as interested as I was in this device might find this pdf (“New Hope for Alzheimer’s” by Dr. lee Bartel)– which I just found the same day I found Tomasz’s excellent blog — useful: https://www.room217.ca/sites/default/files/media/uploaded/pdf/room-217-downloadables/Room217%20Webinar%20%20Feb%2014%202018%20New%20Hope%20for%20Alzheimer%27s%20-%20Dr%20Lee%20Bartel.pdf, Tomasz P. Szynalski 40 Hz LIGHT THERAPY Exposure to light pulsing at 40Hz appears to boost the activity of the brain’s immune cells and slow down neurodegenerative diseases such as Alzhaimer’s. They can sometimes be taped back together and work OK. * Very comfortable with puffy leatherette cushions for a good seal on the ears. I live in Australia so hope you wouldn’t mind sending them Downunder. gamma sound and vibratory stimulation to treat Alzheimer’s, among other diseases. With headphones, the effect is strictly auditory. Tablets typically have screens that refresh at 60 Hz or 120 Hz (iPad Pro). I am touched to read about so many personal stories. evoced electrical signals). I’m listening to the the 40 Hz on my iMac with a set of plug-in ear buds that used to come with Apple products. 40hz becomes the dominant frequency of these monks while meditating and it is also the frequency that the core of Earth resonates to. Thank you. Because they are the 'fastest' brain wave activity, they also have the smallest amplitude on an E.E.G. Don, Tomasz P. Szynalski I have been using the 40 hz tone to treat my wife. The low E note of a bass guitar is 41 hz for reference. I have not seen any indications as to what volume these tests are being conducted at. My husband likes the sound to be on, but he can’t do it when he’s meditating, he says it interferes with the waves he’s trying to generate when in meditation. The tACS administrator and participants will be blinded to the stimulation type. (I don’t know how the NYT and Boston Globe managed to mangle the files so badly, but it’s not because of compression – I tried it on the same encoder and the same parameters that were used by the NYT and it did not distort the signal very much at all.). Mar 11, 2020 at 3:42 am. Introduction The accumulation of amyloid-beta (Aβ) is one of the neuropathologic hallmarks of Alzheimer’s disease (AD) and abnormal gamma band oscillations and brain connectivity have been observed. You will need decent speakers. So there´s no need for a Cheers. Hi, Are you still making the 40 Hz sound and LED glasses? frequency generator using the sawtooth wave form. This article discusses the work of a colleague of Dr. Bartel, Dr. Amy Clements-Cortes; in the article she mentions a patient with early signs of dementia who used a device at home for three years and whose cognition stayed the same during that time. You may not alter the images provided, other than to crop them to size. So I have continued to use your tone generator using a 40Hz sine wave for about an hour each day. the base control completely. showed that a ring of 10 white-light LEDs flickering at 40 Hz was effective for modulating 40 Hz brain activity in healthy participants. Introduction. Clicks played at 40 Hz an hour a day for a week reduced levels of beta-amyloid in the auditory cortex and nearby hippocampus, a part of the brain responsible for learning and memory. the brain. After an hour of stimulation at 40 hertz, the researchers found a 40 to 50 percent reduction in the … Yes, that I what I understood from the article. Sep 26, 2020 at 10:53 pm, If people Google”40Hz Alzheimer’s”, you can find a number of studies that are not behind a paywall, such as: Noninvasive treatment improves memory and reduces amyloid plaques in mice. Antiphasic 40 Hz Oscillatory Current Stimulation Affects Bistable Motion Perception ... noninvasive human brain stimulation are now available that allow for driving brain oscillations within the range of observable, physiologically relevant frequencies (Thut et al. The brain tries to adapt to a given external to the harmonics, the higher frequencies. I’d still say give it a try – it costs nothing. So now 7 weeks on the improvement in her awareness has continued to the point where she is starting to be able to put a few words together and to respond to questions neither of which she has been able to do for nearly a year. A short-duration intervention with 40 Hz light flicker has been shown to reduce brain Aβ load in transgenic mice. In order to understand the nature of these spontaneous creative visions and whether their content could be modulated by brain stimulation, we performed three brain stimulation conditions during the meditation of L.C. Creative Commons Attribution Non-Commercial No Derivatives license. (Please note I do not take responsibility for the purity of the produced tone, as it is generated by your Web browser – though I think it should be fine. It looks like the backrest of a chair and it has built-in speakers (in an interview also available on youtube Dr. Bartel says it is like “sitting on a subwoofer”). 160 Hz would be ideal. I was researching the work of Dr. Tsai at MIT when I came across an article related to the University of Toronto research titled “How flashing lights could treat Alzheimer’s disease,” available at this link: https://www.bbc.com/future/article/20200519-alzheimers-can-flashing-lights-provide-a-new-treatment. A multidisciplinary neuroscience study using rare, intraoperative brain recordings suggests that low frequency stimulation of a deep brain region may … On the other hand, it appears that the most recently published MIT study used series of clicks (despite previous reports) rather than a tone. These waves indicate the brain is working “at full speed”, activating different brain regions. Thanks in advance (and crossing my fingers…! (Dementia sufferers get very fidgety!). A further possibility would be, to applicate a 40 Hz signal Dennis seems to have had great results with cheap computer speakers. The setup used by Dennis. They are conducting. Considering these previous data, the main objective was to compare the effects of 130 Hz EPN-DBS with stimulations at 40 Hz and 15 Hz on the severity of dystonia in the present study. It´s short pulses. I don’t have Alzheimer’s Disease, but I have noticed my brain works better. Of course I expect there to be a limit to this progress as in the 8 years since my wife was first diagnosed her brain will have shrunk considerably so I do not expect her memory to return but on the other hand my wife’s quality of life has been improved. Almost like using a dimmer switch up and down, rather than an on/off switch. Meanwhile, I’m listening to 40 Hz signal at szynalski’s. I have no trouble hearing the sound – these are good speakers – but I also feel it, as well. Please let me know if you could make me a pair of the glasses. So are you seeing positive results in your wife? I was planning on buying the device anyway after reading the BBC article. Her odd physical habits have not been changed so far but she is definitely walking better and not shuffling her feet as she used to. Hi Steve – I would be very interested exploring the device you made for my family. 41 instead of 40 Hertz! Simple. Nov 9, 2019 at 4:59 pm. Since 40 Hz seems generally implicated in intra-brain communication , may stimulate neural outgrowth , shows a decrease with the onset of AD, and has the potential to drive gamma response with auditory or somatosensory stimulation , 40 Hz appears to be a logical frequency for brain stimulation in AD patients and this study provides some evidence of its effect. The black box on the left is the external speaker. Higher than that reflected by beta waves, which are those present when a person is deep in thought. To read more on the published research, follow the link below. It is not known to what extent the therapeutic effect depends on volume or the presence of distortion. I have tried listening to the 40hz clicks vs the 40hz tone that you made and I cannot tolerate the clicks at all using my headphone with my iPhone. Here is his response: I reached a point when I knew that my wife’s condition was worsening so after [about 8 months] I gave up using the sound treatment. I am very interested to discover that you can build a product that may help me with my brain. “sawtooth” in the online sound generator. Hello, And your loudspeaker in your "We found an increase in cytokines after an hour of stimulation," Garza said. Gamma brain waves are a frequency pattern of normal brain activity that measures between 25 and 100 Hz, with around 40 Hz being typical in humans.. Gamma waves were essentially unknown before the development of digital EEG (electroencephalography) recorders since analog electroencephalography could not measure brain waves at that high frequency (their upper limit is about 25 Hz). We used functional brain imaging with positron emission tomography (PET)-H2 15O to study a remarkable neurophysiological finding in the normal brain. 1Khz would be 1ms long, i.e. If you are an electronics technician or radio amateur, Hi, In my first session my 33 year old brain brain could only handle 14 minutes . Wide-ranging contributions over a span of seven decades advanced nuclear waste disposal and fuel cycle development. Amazingly, when the brain was stimulated with a current frequency of 25 or 40 Hz, similar to that of gamma waves, the volunteers reported an increase in lucidity compared to other stimulation frequencies. I am currently ‘testing’ on my father-in-law, after 1 week of 1 hour a day sessions he and others have noticed improvements. “These microglia just pile on top of one another around the plaques,” Tsai says. I just saw your post from some months ago in the archives. Thank you very much! The results have been very positive, but, the number to participants has very been small. “It’s stunning that the intervention had beneficial effects on so many different aspects of Alzheimer-like pathology,” said Dr. Lennart Mucke, director of the Gladstone Institute of Neurological Disease. I would also be interested in purchasing your device. oscillating between 40 Hz and 100 Hz. I am UK based and my father is suffering from memory issues after 3 strokes. Dr. Bartel and others at the University of Toronto have conducted research using 40 Hz. Because the ear is more sensitive to high frequencies, the distortion may be subjectively louder than the fundamental 40 Hz tone, and may make the sound harder to tolerate, thus limiting the volume (and possibly the therapeutic effect). A 40 Hz sine wave is a very deep tone. My hearing is zip in that range. If anyone is interested in a device, I can make them to order (UK). 40 Hz is a physically long wavelength, the full wave is 28 feet long. It would be very interesting to know what sort of tones are being used in the now ongoing human trials. And secondly, this auditory-stimulation-induced gamma can reduce amyloid and Tau pathology in not just the sensory cortex but also in the hippocampus,” says Tsai, who is a founding member of MIT’s Aging Brain Initiative. Jon Ahlquist https://drive.google.com/open?id=1QIddtKGOYx9BO5visNPKc9EkjjiwPkYY, Mikko Rantalainen (electroencephalogram) in comparison to the other major ranges of brain wave frequencies. In this case no connection to the mains is allowed, only Interested, I contacted Dr. Clements-Cortes to inquire whether the device is available to consumers. When this auditory treatment was combined with light pulses at 40 Hz, Cognito Therapeutics are now trying to commercialize their early findings by developing a device (called “GammaSense”) that combines visual and auditory stimulation. SWE members develop innovative and creative ways to maintain programming during the pandemic. cannot reproduce this at all! Many thanks! This leads to the question, how to applicate this 40 Hz? Do you have an opinion or information on this: Steve, how much do you charge for the device? Sep 9, 2019 at 6:55 pm. This training is permanent and much much stronger then just audio signals. What is distortion? Worked nicely. 10 Khz would be 0.1ms long right? When that happens, it creates alterations in consciousness itself and promote altered states of consciousness. You would need expensive sawtooth generator add a further so called RC-derivative However, the precise molecular and cellular mechanisms by which gamma … Put in "computerese," 40-Hz may be the brain's "operating system" frequency [GIA via DW] Involved In The Processing Of Psi Information (see note) [EMC] Study shows reversed signs of Alzheimer's in mice. The researchers have already performed some preliminary safety tests of this type of stimulation in healthy human subjects. We have added 40hz brain stimulation. They found that after one week of treatment, the mice performed much better when navigating a maze requiring them to remember key landmarks. Compare the right 40 Hz frequency with the online 40 Hz acoustic stimulation decreases amyloid beta and modulates brain rhythms in a mouse model of Alzheimers disease. The beat frequencies of 40 Hz and 16.3 Hz were chosen for experimental conditions with strong and weaker entrainment of 40-Hz oscillations, respectively. Intracranial AC stimulation and the estimated current distribution. We tested units over several years hundreds of users who reported mood brightening, improved concentration, clarity of thought, assistance in meditation and the stopping of circular thoughts which aided sleep. (A) Frequency spectra of auditory cortex responses to beat stimulation between 3 Hz and 60 Hz.The beat frequencies of 40 Hz and 16.3 Hz were chosen for experimental conditions with strong and weaker entrainment of 40-Hz oscillations, respectively.B accoustic and vibration stimulation. oscillating between 40 Hz and 100 Hz. To date I have not gone public on this and only close family have known but by the end of another week when it will be 8 weeks since we started I think I would like to spread the word and hopefully prompt a few professionals to do more proper research. Magic of 40 Hertz Stimulation This brain research article shows that 40 Hertz brainwaves are associated with meditation, clarity of thought and optimal brain functioning. Put in "computerese," 40-Hz may be the brain's "operating system" frequency [GIA via DW] Involved In The Processing Of Psi Information (see note) [EMC] Study shows reversed signs of Alzheimer's in mice. If you’re still making these devices, please send me information about how to purchase one. Previous studies have suggested that Alzheimer’s patients have impairments of their gamma-frequency oscillations, which range from 25 to 80 hertz (cycles per second) and are believed to contribute to brain functions such as attention, perception, and memory. It makes a very clear good sounding sine wave. 120 Hz screens will sort of do it, but not accurately. Aylene Bowman It regards and treats Alzheimer as a muli-factor lifestyle disease – with the ketoflex diet being the most important intervention. I’m in the US. Optoceutics is currently planning clinical trials on the potential effect of masked 40 Hz light on Alzheimer’s Disease patients. Higher than that reflected by beta waves, which are those present when a person is deep in thought. We both tolerate the sound very well. August 20, 2018. Also, since I have an I phone, the headphones you recommended do not work with it. I turn the sound on every morning at the sine wave setting and leave it on all day. Amazingly, when the brain was stimulated with a current frequency of 25 or 40 Hz, similar to that of gamma waves, the volunteers reported an increase in lucidity compared to other stimulation frequencies.. If you are thinking about using clicks rather than pure tones, I would not recommend using 10 kHz clicks because human ears are not very sensitive to that range of the spectrum. He is no longer sleeping during the day and his mood has improved, he seems more alert. battery supply! That´s what we need! the idea is that your body works in the area of 40-100hz and if you listen to the sound somehow your body begins to tune itself to the same frequency. Nerve cells do not generate Prof. Li-Huei Tsai speaks with Anthony Everett of WCVB-TV’s Chronicle about her work developing a non-invasive technique that uses the power of light and sound and could potentially help treat or even cure Alzheimer’s disease. Since then, I have heard from people using my generator to teach physics, practice violin, drive away carpenter bees, tune DIY speakers, analyze room acoustics, calibrate vintage synthesizers, cause mischief in class with frequencies the teacher can’t hear, and even open a portal to Sedona, AZ. I am not convinced one needs to “hear” the tone. It feels like a rumbling of thunder in my chest. The researchers found that if they treated the mice for one week, then waited another week to perform the tests, many of the positive effects had faded, suggesting that the treatment would need to be given continually to maintain the benefits. We definitely intend to continue using the device after the study ends, and we are thinking about adding 40 hz flickering light if there are no contraindications. What is Deep Brain Stimulation (DBS) Deep brain stimulation (DBS) is a neurosurgical therapy in which a thin lead with a number of electrode contacts at the tip is chronically implanted in deep brain structures, and delivers electrical pulses (60-200 μs duration, 1-5 V amplitude) at high frequency (typically > 130 Hz) to surrounding brain tissue through one or a combination of electrode contacts. sound, vibration and light in combination. So you will Dennis, the reader from the UK who piqued my interest in this subject, used a pure 40 Hz tone. 40 Hz is a very deep bass tone – the kind of rumbling tone that you feel in your body as much as you hear it. Over the last century people have used various frequencies for these devices. “When we combine visual and auditory stimulation for a week, we see the engagement of the prefrontal cortex and a very dramatic reduction of amyloid,” says Li-Huei Tsai, director of MIT’s Picower Institute for Learning and Memory and the senior author of the study. Hello Steve! Our Gamma 40 Hz Light & Sound Therapy Devices are made to address the growing need for alternative therapies for those looking to promote gamma brain wave activity. Can you check it fits the researchers’ specs after being compressed for mp3 etc.? Please let me know as I am in the US but also have family in the UK. my $39 20hz-20khz headphones reproduce it super cleanly no issue and the sternum does respond aka the bones do vibrate regardless. The model nuber is the VTS1000. I haven’t read all of it yet, but one big takeaway from the BBC article (if it is accurate) is that Dr. Tsai uses a series of clicks rather than a 40 Hz tone. In the link at the very bottom of my comments above, Dr. Bartel mentions small studies using 40 Hz. The clicks in the published samples are smeared in time (closer to 2 ms) and are not pure 10 kHz tones. In order to understand the nature of these spontaneous creative visions and whether their content could be modulated by brain stimulation, we performed three brain stimulation conditions during the meditation of L.C. Here are my personal experiences with a 40hz tone. How to prevent back problems – FAQ for computer workers, It has been known since at least the 1980s that, In 1991, researchers from the NYU Medical Center discovered that, In 2016, MIT’s Alzheimer’s group did experiments on, In March 2016, scientists at the University of Toronto published the results of a small, placebo-controlled pilot study (. I’m in the US. A neat trick to amplify the bass output of any speaker is to place it against as many walls as possible. AD pathology is characterized by abnormal aggregation of the proteins amyloid-β (Aβ) and hyperphosphorylated tau. All devices used in trials are considerd investigational devices and limited to investigational use only. (I do understand that any experimentation I choose to do on myself …is of course my own decision and my responsibility). If you or your loved one has Alzheimer’s disease and you have tried 40 Hz sound therapy, please share your experiences – whether positive or negative – in the comments section below. Don’t experiment with people with those tones. I’ve been using 40hz sine wave with headphones for 3o minutes a day three times a week for a couple of months. "Parts of the brain appear to need to be at the same communication frequency, and that frequency is about 40 Hz," said Bartel. []. It is not offensive at that low frequency. Also, the click should start and end with a short fade to avoid high frequency artifacts. Very intriguing work. A short-duration intervention with 40 Hz light flicker has been shown to reduce brain Aβ load in transgenic mice. But this is for experts, only. In Frequency Specific Microcurrent therapy, 40 Hz is used for lowering inflammation. The treatment also stimulated the activity of debris-clearing immune cells known as microglia. My wife’s uncle has alzheimers and may be able to benefit from your device. , Gerhard Umlandt A recent study by Jones, et al. I get dizzy and beryls uncomfortable even after just a few minutes. 40 Hz Doorway to all other frequencies Gamma brainwaves are usually very weak in normal people but have recently been found to be very strong in Tibetan monks while doing a Loving Kindness meditation. The clicks were 10 kHz waves, 1 millisecond long, repeated 40 times a second (each cycle had a 1 ms tone followed by 24 ms of silence). gamma activity is largely a product of glial cell activity. 30 seconds after that, the volunteers were woken up and asked questions about their dreams. Forty--Hz pulses are thought to lead to synchronization + coordination of neurons assigned to the processing of incoming sensory stimulation. Play nice tones instead, calming nature sounds or music from their youth. 40 Hz foundamental sine wave, but harmonic waves with produces needle pulses or sawtooth wave form with I mention this, because that fact might have some bearing on the effectiveness of sound therapy. Gamma is thought to act as a binding mechanism that holographically synthesizes and unifies data throughout the brain, analogous to the 'oil in an engine' integrating other functions. professional loudspeakers, if you want to perform a pure AD pathology is characterized by abnormal aggregation of the proteins amyloid- β (A β ) and hyperphosphorylated tau. In the lore of fibromyalgia, we have this thing we call “fibro fog” which makes it hard to concentrate sometimes. I’ve gotten in touch with Dennis Tuffin to ask about his long-term experiences with 40 Hz therapy. Selasie Agbavor https://www.nia.nih.gov/news/noninvasive-brain-wave-treatment-reduces-alzheimers-pathology-improves-memory-mice he said that 40hz didn’t just help alzheimer’s but also helped a woman with fibromyalgia get off of all of her medications. For the maximum boost, put the speaker(s) on the floor, in a 3-way corner between two walls and the floor – that way, it will be adjacent to three surfaces. She said it was, and she asked whether we were interested in taking part in a study using the device (I am helping to care for a relative with clear symptoms of dementia but with no pathological diagnosis). The 40 Hz stimulation did not need long to trigger the cytokine surge. Alzheimer’s disease (AD) is a progressive neurodegenerative disorder. I am looking for some kind of 40 Hz lighting device to add to the 40 Hz. If you want to try some kind of do-it-yourself auditory therapy, it’s not clear what kind of tones you should use. I’m interested in getting one of your devices. I am interested in knowing more about your product. The New York Times quotes Dr. Tsai, who worked on that study, as saying “your brain seems to be able to perceive clicks more than a tone”, which would seem to indicate a preference that’s not exclusive to mice. It can’t hurt anything! If the UK to US shipping (and electric plug) make it impractical to sell to me in the US, perhaps you could share info and my husband could build it for me? Patrick VeVea After an hour of stimulation at 40 hertz, the researchers found a 40 to 50 percent reduction in the levels of beta amyloid proteins in the hippocampus. To get a beat frequency of 40 Hz, just play 2 tones that are 40 Hz apart in frequency, e.g. Thank you for posting all this information. They have surprising sound quality, a hint that they may be culls from expensive driver production lines. All participants will receive all three stimulation types during separate visits. These waves indicate the brain is working “at full speed”, activating different brain regions. What´s our aim? HeadRoom has a database of frequency response graphs for high-quality headphones, so you can check how loud a given model is at 40 Hz. We utilized a Light Emitting Diode (LED) light bulb with … [here Dennis is referring to this paywalled article]. While this doesn’t mean you need to be in a large room to hear it it does mean that much of the bodies ‘awareness’ of the sound is distributed across more than just the ears. In a study reported in Cell April 4, MIT researchers further explored the effects of gamma wave stimulation using sound in Alzheimer’s mouse models. Maybe you know the allows to pass through higher frequencies, only, so that a laptop or pc with such a simple task). No effective disease modifying therapies are currently available. “The study’s central finding — that inducing electrical synchrony touched off such a widespread range of effects — suggests there might be a single key lever that can preserve or restore order in brains made 'noisy' by age and disease,” Healy explains.
