Brainwave Abnormality Could Be Common to Parkinson’s Disease, Tinnitus, Depression
Vanneste and his colleagues—Dr Jae-Jin Song of South Korea’s Seoul National University and Dr Dirk De Ridder of New Zealand’s University of Otago—analyzed electroencephalograph (EEG) and functional brain mapping data from more than 500 people to create what Vanneste believes is the largest experimental evaluation of TCD, which was first proposed in a paper published in 1996.
“We fed all the data into the computer model, which picked up the brain signals that TCD says would predict if someone has a particular disorder,” Vanneste said. “Not only did the program provide the results TCD predicted, we also added a spatial feature to it. Depending on the disease, different areas of the brain become involved.”
“The strength of our paper is that we have a large enough data sample to show that TCD could be an explanation for several neurological diseases.”
Brainwaves are the rapid-fire rhythmic fluctuations of electric voltage between parts of the brain. The defining characteristics of TCD begin with a drop in brainwave frequency—from alpha waves to theta waves when the subject is at rest—in the thalamus, one of two regions of the brain that relays sensory impulses to the cerebral cortex, which then processes those impulses as touch, pain, or temperature.
A key property of alpha waves is to induce thalamic lateral inhibition, which means that specific neurons can quiet the activity of adjacent neurons. Slower theta waves lack this muting effect, leaving neighboring cells able to be more active. This activity level creates the characteristic abnormal rhythm of TCD.
“Because you have less input, the area surrounding these neurons becomes a halo of gamma hyperactivity that projects to the cortex, which is what we pick up in the brain mapping,” Vanneste said.
While the signature alpha reduction to theta is present in each disorder examined in the study—Parkinson’s, pain, tinnitus, and depression—the location of the anomaly indicates which disorder is occurring.
“If it’s in the auditory cortex, it’s going to be tinnitus; if it’s in the somatosensory cortex, it will be pain,” Vanneste explained. “If it’s in the motor cortex, it could be Parkinson’s; if it’s in deeper layers, it could be depression. In each case, the data show the exact same wavelength variation—that’s what these pathologies have in common. You always see the same pattern.”
EEG data from 541 subjects was used. About half were healthy control subjects, while the remainder were patients with tinnitus, chronic pain, Parkinson’s disease, or major depression. The scale and diversity of this study’s data set are what set it apart from prior research efforts.
“Over the past 20 years, there have been pain researchers observing a pattern for pain, or tinnitus researchers doing the same for tinnitus,” Vanneste said. “But no one combined the different disorders to say, ‘What’s the difference between these diseases in terms of brainwaves, and what do they have in common?’ The strength of our paper is that we have a large enough data sample to show that TCD could be an explanation for several neurological diseases.”
With these results in hand, the next step could be a treatment study based on vagus nerve stimulation—a therapy being pioneered by Vanneste and his colleagues at the Texas Biomedical Device Center at UT Dallas. A different follow-up study will examine a new range of psychiatric diseases to see if they could also be tied to TCD.
For now, Vanneste is glad to see this decades-old idea coming into focus.
“More and more people agree that something like thalamocortical dysrhythmia exists,” he said. “From here, we hope to stimulate specific brain areas involved in these diseases at alpha frequencies to normalize the brainwaves again. We have a rationale that we believe will make this type of therapy work.”

New Hearing Devices in Development May Expand Range of Human Hearing
Researchers at Case Western Reserve University are developing atomically thin ‘drumheads’ able to receive and transmit signals across a radio frequency range far greater than what we can hear with the human ear, the University announced in a press release.
But the drumhead is tens of trillions times (10 followed by 13 zeros) smaller in volume and 100,000 times thinner than the human eardrum.
It’s been said that the advances will likely contribute to making the next generation of ultralow-power communications and sensory devices smaller and with greater detection and tuning ranges.
“Sensing and communication are key to a connected world,” said Philip Feng, an associate professor of electrical engineering and computer science and corresponding author on a paper about the work published March 30 in the journal Science Advances. “In recent decades, we have been connected with highly miniaturized devices and systems, and we have been pursuing ever-shrinking sizes for those devices.”
The challenge with miniaturization: Also achieving a broader dynamic range of detection, for small signals, such as sound, vibration, and radio waves.
“In the end, we need transducers that can handle signals without losing or compromising information at both the ‘signal ceiling’ (the highest level of an undistorted signal) and the ‘noise floor’ (the lowest detectable level),” Feng said.
While this work was not geared toward specific devices currently on the market, researchers said, it was focused on measurements, limits, and scaling which would be important for essentially all transducers.
Those transducers may be developed over the next decade, but for now, Feng and his team have already demonstrated the capability of their key components—the atomic layer drumheads or resonators—at the smallest scale yet.
The work represents the highest reported dynamic range for vibrating transducers of their type. To date, that range had only been attained by much larger transducers operating at much lower frequencies—like the human eardrum, for example.
“What we’ve done here is to show that some ultimately miniaturized, atomically thin electromechanical drumhead resonators can offer remarkably broad dynamic range, up to ~110dB, at radio frequencies (RF) up to over 120MHz,” Feng said. “These dynamic ranges at RF are comparable to the broad dynamic range of human hearing capability in the audio bands.”
New dynamic standard
Feng said the key to all sensory systems, from naturally occurring sensory functions in animals to sophisticated devices in engineering, is that desired dynamic range.
Dynamic range is the ratio between the signal ceiling over the noise floor and is usually measured in decibels (dB).
Human eardrums normally have dynamic range of about 60 to 100dB in the range of 10Hz to 10kHz, and our hearing quickly decreases outside this frequency range. Other animals, such as the common house cat or beluga whale, can have comparable or even wider dynamic ranges in higher frequency bands.
The vibrating nanoscale drumheads developed by Feng and his team are made of atomic layers of semiconductor crystals (single-, bi-, tri-, and four-layer MoS2 flakes, with thickness of 0.7, 1.4, 2.1, and 2.8 nanometers), with diameters only about 1 micron.
They construct them by exfoliating individual atomic layers from the bulk semiconductor crystal and using a combination of nanofabrication and micromanipulation techniques to suspend the atomic layers over microcavities predefined on a silicon wafer, and then making electrical contacts to the devices.
Further, these atomically thin RF resonators being tested at Case Western Reserve show excellent frequency ‘tunability,’ meaning their tones can be manipulated by stretching the drumhead membranes using electrostatic forces, similar to the sound tuning in much larger musical instruments in an orchestra, Feng said.
The study also reveals that these incredibly small drumheads only need picoWatt (pW, 10^-12 Watt) up to nanoWatt (nW, 10^-9 Watt) level of RF power to sustain their high frequency oscillations.
“Not only having surprisingly large dynamic range with such tiny volume and mass, they are also energy-efficient and very ‘quiet’ devices,” Feng said. “We ‘listen’ to them very carefully and ‘talk’ to them very gently.”

Visual Cues May Help Amplify Sound, University College London Researchers Find
Looking at someone’s lips is good for listening in noisy environments because it helps our brains amplify the sounds we’re hearing in time with what we’re seeing, finds a new University College London (UCL)-led study, the school announced on its website.
The researchers say their findings, published in Neuron, could be relevant to people with hearing aids or cochlear implants, as they tend to struggle hearing conversations in noisy places like a pub or restaurant.
The researchers found that visual information is integrated with auditory information at an earlier, more basic level than previously believed, independent of any conscious or attention-driven processes. When information from the eyes and ears is temporally coherent, the auditory cortex —the part of the brain responsible for interpreting what we hear—boosts the relevant sounds that tie in with what we’re looking at.
“While the auditory cortex is focused on processing sounds, roughly a quarter of its neurons respond to light—we helped discover that a decade ago, and we’ve been trying to figure out why that’s the case ever since,” said the study’s lead author, Dr Jennifer Bizley, UCL Ear Institute.
In a 2015 study, she and her team found that people can pick apart two different sounds more easily if the one they’re trying to focus on happens in time with a visual cue. For this latest study, the researchers presented the same auditory and visual stimuli to ferrets while recording their neural activity. When one of the auditory streams changed in amplitude in conjunction with changes in luminance of the visual stimulus, more of the neurons in the auditory cortex reacted to that sound.
“Looking at someone when they’re speaking doesn’t just help us hear because of our ability to recognize lip movements—we’ve shown it’s beneficial at a lower level than that, as the timing of the movements aligned with the timing of the sounds tells our auditory neurons which sounds to represent more strongly. If you’re trying to pick someone’s voice out of background noise, that could be really helpful,” said Bizley.
The researchers say their findings could help develop training strategies for people with hearing loss, as they have had early success in helping people tap into their brain’s ability to link up sound and sight. The findings could also help hearing aid and cochlear implant manufacturers develop smarter ways to amplify sound by linking it to the person’s gaze direction.
The paper adds to evidence that people who are having trouble hearing should get their eyes tested as well.
The study was led by Bizley and PhD student Huriye Atilgan, UCL Ear Institute, alongside researchers from UCL, the University of Rochester, and the University of Washington, and was funded by Wellcome, the Royal Society; the Biotechnology and Biological Sciences Research Council (BBSRC); Action on Hearing Loss; the National Institutes of Health (NIH), and the Hearing Health Foundation.

ADM Tronics Unlimited, Inc (OTCQB: ADMT), a technology-based developer and manufacturer of innovative technologies, has authorized its subsidiary, Aurex International Corporation (“AIC”) to begin advertising its new hearing protection product, Tinnitus Shield™ in Tinnitus Today, the official publication of the American Tinnitus Association, ADM announced.
Tinnitus Shield™ has been designed to protect against damaging sounds shown to cause tinnitus for individuals at risk of acquiring this condition, according to the company’s announcement. These include military, police, musicians, construction workers, and many other occupations subject to Noise-Induced Hearing Loss (NIHL).
The US Veterans Health Administration (VA) reports that tinnitus is the most prevalent combat-related disability affecting veterans, making it a high-priority healthcare issue facing the military and the VA.
While Tinnitus Shield™ has been specifically engineered to protect against the sounds which may cause tinnitus, AIC also plans to bring to market Aurex-3®, a patented, non-invasive therapy technology for the treatment and control of tinnitus.
Heading up AIC is CEO Mark Brenner, BSc, PhD, who draws upon years of experience serving the tinnitus market in the United Kingdom. Brenner brings with him the vision and resources necessary to set in motion the launching and distribution of Aurex-3 throughout the US and Europe. For these reasons, the company believes that under Brenner’s leadership and guidance, both AIC technologies can effectively penetrate this burgeoning market.
“The potential market for effective technologies that addresses the tinnitus marketplace is significant, considering the millions and millions of sufferers in the US and worldwide,” said Andre’ DiMino, president of ADMT.
Brenner commented, “AIC is now able to offer the full spectrum of support to the worldwide tinnitus community with its Tinnitus Shield, providing protection from noise-induced tinnitus, and the Aurex-3, as an active treatment and management system for those who have developed tinnitus. This is receiving great interest in the UK where we are actively working with The Tinnitus Clinic, a group of specialist tinnitus clinics. In the US we have active discussions with the American Tinnitus Association.”

Want to know what A.I. Hell is like?
How about interacting with a machine that repeatedly professes stupefaction when you just know it should know what you’re talking about?
I was excited when I heard last fall that Alphabet’s (GOOGL) Google’s new wireless ear pieces would perform a kind of “real time” translation of languages, as it was billed.
The ear pieces, “Pixel Buds,” which arrived in the mail the other day, turn out to be rather limited and somewhat frustrating.
They are in a sense just a new way to be annoyed by the shortcomings of Google’s A.I., Google Assistant.
The devices were unveiled at Google’s “Made By Google” hardware press conference in early October, where it debuted its new Pixel 2 smartphone, which I’ve positively reviewed in this space, and its new “mini” version of the “Google Home” appliance.
The Buds retail for $159 and can be ordered from Google’s online store.
Getting the things to pair with the Pixel 2 Plus that I use was problematic at first, but eventually succeeded after a series of attempts. I’ve noticed some similar issues with other Bluetooth-based devices, so I soldiered on and got it to work.
The sound quality and the fit is fine. The device is very lightweight, and the tether that connects the two ear pieces — they are not completely wireless like Apple’s (AAPL) AirPods — snakes around the back of one’s neck and is not uncomfortable.
The adjustable loops on each ear piece made the buds fit in my ears comfortably and stay there while I moved around. So, good job, Google, on industrial design.
Translating was another story.
One has to first install Google Translate, an application from Google of which I’m generally a big fan. Google supports translation in the app of 40 languages initially.
You invoke the app by putting your finger to the touch-sensitive spot on the right ear piece and saying something like, “Help me to speak Greek.” When you lift your finger, it invokes the Google Assistant on the Pixel 2 phone, who tells you in the default female voice that she will launch the Translate app.
Several times, however, the assistant told me she had no idea how to help. Sometimes she understood the request the second time around. It seemed to be hit or miss whether my command was understood or was valid. On a number of other occasions, she told me she couldn’t yet help with a particular language, even though the language was among the 40 offered. It seemed like more common languages, such as French and Spanish, elicited little protest. But asking for, say, the Georgian language to be translated stumped her, even though Georgian is in the set of supported tongues.
This dialogue with the machine to get my basic wishes fulfilled fell very far below the Turing Test:
Me: “Help me to speak Greek.”
Google: “Sorry, I’m not sure how to help with that yet.”
Me: “Help me to translate Greek.”
Google: “Sure, opening Google Translate.”
Me: “Help me to speak Georgian.”
Google: “Sorry, I’m not sure how to help with that.”
Me: “Help me to speak Georgian.”
Google: “Sorry, I don’t understand.”
Me: “Help me to speak Georgian.”
Google: “Sorry, I can’t help with that yet, but I’m always learning.”
Me: “Help me to translate Georgian.”
Google: “Sorry, I don’t know how to help with that.”
In answer to Thomas Friedman of The New York Times, who writes of a new era of “continuous learning” for humans, I would like all humans to tell their future robot masters, “Sorry, I can’t help with that yet, but I’m always learning.”
When it does work, the process of translating is a little underwhelming. The app launches, and you touch the right ear piece’s touch-sensitive area, and speak your phrase in your native language. As you’re speaking, Google Translate is turning that into transcribed text on the screen, in the foreign script. When you are fully done speaking, the entire phrase is played back in the foreign language through the phone’s speaker for your interlocutor to hear. That person can then press an icon in the Translate app and speak to you in their native tongue, and their phrase is played for you, translated, through your ear piece.
Even this doesn’t always go smoothly. Sometimes, after asking for help with one language, the Google Assistant would launch the Translate app and the app would be stuck on the previously used language. At other times, it was just fine. In the worst instances, the application would tell me it was having audio issues when I would tap the ear piece to speak, requiring me to kill the app and start again.
This is all rather cumbersome.
I went and tried Translate on my iPhone 7 Plus, using Apple’s AirPods, and had pretty much an equivalent experience, with somewhat less frustration. All I had to do was to double-tap the AirPods and say, “Launch Google Translate,” and then continue from there as normal. It’s slightly more limited in that the iPhone’s speaker is not playing back the translation for my interlocutor; that plays through the AirPods. But on the flip side, it’s actually a little easier to use the app because one can maintain a kind of “open mic” by pressing the microphone icon. The app will then continuously listen for whichever language is spoken, translating back and forth between the two constantly, rather than having to tell it at each turn who’s speaking.
All in all, then, Pixel Buds are just a fancy interface to Google Translate, which doesn’t seem to me revolutionary, and is rather less than what I’d hoped for, and very kludgy. It’s a shame, because I like Google Translate, and I like the whole premise of this enterprise.
At any rate, back to school, Google, keep learning.
