“Vitamin D + Autism symptoms

Vitamin D is not really a vitamin at all – it is a pre-hormone that’s produced in your skin in response to sunlight exposure. As such, it is an integral part of human health and longevity.

Dr. Cannell answers reader’s questions and sheds light on some of the latest papers on

vitamin D. 

On Autism

Dear Dr. Cannell:
My son James weighs 48lb, he is 7 yrs old. He had autistic symptoms for almost 5 years (first noticed when he was 2 yrs old). I initially started him on 2,000 IU last November after he caught the flu. Two weeks later, I noticed improvements in areas of social interaction, verbalization. I then increased his dosage to 5,000 IU per your recommendation, and he got better.

His progress has been so great that his kindergarten teacher and Speech Therapist have recommended that he exit the Early Intervention Program.

He is more social, making friends easily, participating in cooperative play, and soon to be in a regular classroom. I think it might be bad luck to say he is cured. Is that possible in a genetic disease? A friend told me he must never have had autism but whatever it was, I don’t want it back. I remember what he was like, and me, too. No thanks.

I’m writing because my son’s pediatrician just called and told me James’s 25(OH) level was 122. He believes he must be toxic because of that level and wants me to stop giving him all vitamin D supplements and recheck his vitamin D level next month. James feels great and shows no signs of toxicity.

What should I do?
Mary, New York

Dear Mary:
That is wonderful news about your son. He is not toxic. However, he should reduce his vitamin D to 2,000 IU/day and recheck his blood level in a month. Some of his symptoms may come back; I don’t know but do not fear, if the symptoms return the vitamin D will take care of them. It appears to me that high dose vitamin D controls, rather than “cures,” some cases of autism. If his level in a month is below 100 ng/ml, the pediatrician will be happy as that is the upper range of normal vitamin D levels.

Yes, autism is a genetic disease, so how can vitamin D treat it? I suspect that one of vitamin D’s many duties in the body is to protect your genome from mutations, organizing the correction of random and point mutations when they occur. Think of your son as having DNA that is unlikely to function properly with lower levels of vitamin D. How long his DNA will be sensitive to low vitamin D, I don’t know.

An immediate question is how much vitamin D to give him now. You want to give him the lowest dose that controls his symptoms. I suspect that he will end up needing 3,000 to 4,000 IU per day to maintain his 25(OH)D around 80-90 ng/ml.

“Want fried glucose in your brain?”

Do you want to serve yourself up some” fried glucose” in your brain? Just use your cell phone for 50 minutes at a time while holding it against your ear. The brain glucose metabolism in the region closest to the phone’s antenna is effected.

What is glucose?   Glucose, blood sugar, the major energy source for brain energy enters the brain from the arterial side and is absorbed by astrocytes, which then transform glucose to lactate. Lactate exchange occurs with neurons, which oxidize it to CO2 and H2O drained by the venous blood. The increase in lactate levels and the uncoupling between oxygen consumption and glucose uptake revealed by PET at the early stages of activation, cause lactate fluxes between astrocytes and neurons.

When you hold a cell phone to your ear in an on position for 50 minutes or more it changes the way glucose moves through the brain cells. The area begins to heat only after 5 minutes and changes the biochemistry as proven by PET scans.
During cell phone use in the on and then off positions and found that although whole-brain metabolism was not affected, metabolism was increased in the orbitofrontal cortex and the temporal pole areas of the brain while the cell phone was on, areas that are close to where phone’s antenna meets the head.(brain energy metabolism).
  
Blood-borne glucose is the brain’s fuel and is needed to supply the moment-to-moment changes in energy demand during information processing, the local rates of blood flow and glucose utilization are closely linked to the activities of brain cells. Because the blood-brain barrier restricts transfer of material from blood into brain, many compounds that are readily metabolized by cultured brain cells or brain slices, including lactate, cannot be transported into adult brain in vivo in sufficient quantities to compensate for inadequate levels of glucose and support the brain’s high and continuous energy demand.
Nora D. Volkow, MD, from the National Institute on Drug Abuse in Bethesda, Maryland Hands-free devices or speaker-phone mode should be used to avoid direct contact of the telephone with the head. Previous work suggests that if the phone is a foot or more away it is very unlikely to have any effects, she said.
Caution may be particularly necessary for children and adolescents whose neural tissue is still developing, Dr. Volkow noted.

Other studies have shown that the effects of radio frequency-modulated electromagnetic fields (RF-EMFs), particularly carcinogenic effects show some relationship between cell phones and the risk of brain tumor development.
Dr. Volkow’s studies over the past 15 years have shown:

  •  the the brain’s function is affected by brain imaging technologies, including PET and magnetic resonance imaging (MRI) these magnetic fields affect brain glucose metabolism,
  •  static magnetic field of a 4-T MRI does not affect brain metabolism
  • when magnetic fields were changed rapidly, which produces electrical currents, there was a significant increase in glucose metabolism in the brain. They wondered whether the RF-EMFs produced by cell phones might do the same thing.

 metabolism in the regions closest to the antenna, the orbitofrontal cortex (the thinking and decision-making area of the  brain) and temporal pole (part of the temporal lobe). The temporal lobe is involved in auditory perception and is home to the primary auditory cortex. It is also important for the processing of semantics in both speech and vision. The temporal lobe contains the hippocampus and plays a key role in the formation of long-term memory. was significantly higher when the cell phone was on.
Henry Lai, PhD, from the Department of Bioengineering at the University of Washington, Seattle, and Lennart Hardell, MD, PhD, from the Department of Oncology at University Hospital, Orebro, Sweden, point out that this is the first investigation in humans of glucose metabolism in the brain after cell phone use.
”The results by Volkow et al add to the concern about possible acute and long-term health effects of radiofrequency emissions from wireless phones, including both mobile and cordless desktop phones,” they write.
”Although the biological significance, if any, of increased glucose metabolism from acute cell phone exposure is unknown, the results warrant further investigation.
“
The effects are unlikely to be mediated by the substantial increase in temperature seen with cell phones given the activation was “quite distant” from where the cell phone made contact, they speculate. Further, since the subjects were only listening rather than talking on the phone, “the effect observed could thus potentially be more pronounced in normal-use situations.”
Another major concern is the effects of unmonitored cell phone towers that spider web across the US each one producing many thousands of times higher EMF’s radiation than a cell phone.

“Last antibiotic standing-losing to Gonorrhea”

The last line of defense for treating gonorrhea is crumbling, according to an article published in the July 8 issue of the Centers for Disease Control and Prevention’s (CDC’s) Morbidity and Mortality Weekly Report.

Cephalosporins, the last class of antibiotics that treat gonorrhea, seem to be losing their effectiveness as the pathogen quickly evolves to bypass the antibiotic.

After 10 years of study, the CDC researchers studying gonorrhea cultures show that higher doses of antibiotics are needed to inhibit growth in the lab The gonorrhea samples collected through the CDC’s Gonococcal Isolate Surveillance Project from male patients in 30 US cities. Close to 6000 isolates were collected each year.

A pattern of emerging resistance is developing says Gail Bolan, MD, director of CDC’s Division of Sexually Transmitted Disease Prevention.

Although no treatment failures have been reported yet in the United States, there have been reports from Asia and other parts of the world suggesting gonorrhea’s declining susceptibility to cephalosporin, said Hillard Weinstock, MD, MPH, from the same division.

At an Impasse

Historically, since the 1930s and 1940s, antibiotics have treated gonorrhea. However, during the past 40 years, the bacteria Neisseria gonorrhoeae has developed resistance to several drugs, including sulfonamides, penicillin, and tetracycline. As recently as 2007, the CDC stopped recommending any fluoroquinolone regimens to treat gonorrhea, leaving cephalosporins the last class of antibiotics standing.

The CDC is down to recommending a cephalosporin (cefixime or ceftriaxone), along with a macrolide antibiotic, preferably azithromycin. Ceftriaxone is the most effective cephalosporin for treating gonorrhea, and azithromycin is better than doxycycline for dual therapy with ceftriaxone, the CDC notes. (Dosing recommendations are available in the article.)

Gonorrhea is one of the most common sexually transmitted diseases. Among serious health consequences, it can lead to infertility in women and increase a person’s risk of acquiring HIV.

Given the possibility of rising resistance, clinicians should be on the lookout for treatment failures, Dr. Bolan said, which will show up as persistent symptoms or a positive follow-up test despite treatment with CDC-recommended antibiotics. Clinicians should also obtain specimens for gonococcal culture from patients whose treatments may have failed. “You need to find labs that are still doing the [gonococcal] culture,” she said.

CDC Recommendations

The CDC recommends that individual providers:

  • promptly treat all patients diagnosed with gonorrhea according to CDC Treatment Guidelines,
  • obtain cultures to test for decreased susceptibility from any patients with suspected or documented gonorrhea treatment failures, and
  • report any suspected treatment failure to local or state public health officials within 24 hours, helping to ensure that any future resistance is recognized early.

Clinicians who care for patients with gonorrhea, especially men who have sex with men in the western United States, should consider having patients return 1 week after treatment for test-of-cure with culture, preferably, or with nucleic acid amplification tests. The CDC report notes that the pattern of cephalosporin susceptibility in the West and among men who have sex with men during 2009 to 2010 resembles the drop in effectiveness observed earlier when a fluoroquinolone-resistant N gonorrhoeae emerged in the United States.

Although Dr. Bolan said she was not aware of any new drug development in the pipeline, the CDC and the National Institutes of Health are running a treatment trial on existing drugs: gentamicin, azithromycin, and gemifloxacin. The trial is expected to yield results by late 2012, said Bob Kirkcaldy, MD, MPH, from the CDC’s Office of Workforce Development and Division of STD Prevention.

“We really do want to have more treatment trials so that we have more treatment options down the pike,” Dr. Bolan said.

However, the development of new antibiotics is unlikely, according to Brad Spellberg, MD, author of Rising Plague: The Global Threat from Deadly Bacteria and Our Dwindling Arsenal to Fight Them. A fellow of the Infectious Diseases Society of America who sits on its antimicrobial availability taskforce, Dr. Spellberg characterized the next several decades as “a very barren period of time” in terms of antibiotics development.

Dr. Spellberg offered 3 reasons to explain his outlook: First, there is a significant scientific challenge. After 60 years of antibiotic discovery, all the low-hanging fruit has been plucked, and developing new antibiotics would be difficult. Second, pharmaceutical companies have found that they make much more money off drugs that target chronic illnesses, not ones consumers will take for only 14 days. Third, “nobody even knows how to do drug trials for antibiotics anymore,” Dr. Spellberg said, and the US Food and Drug Administration’s requirements, he explained, are unclear, infeasible, and/or unreasonable.

“There’s never going to be an endgame to this,” he said. Industry, he predicted, will exit antibiotic development. “It doesn’t make enough money for them, and the regulatory morass exacerbates the problem.” Morb Mortal Wkly Rep. 2011:60;873-877. Full text

What are the signs and symptoms of gonorrhea?

Some men with gonorrhea may have no symptoms at all. However, some men have signs or symptoms that appear one to fourteen days after infection. Symptoms and signs include a burning sensation when urinating, or a white, yellow, or green discharge from the penis. Sometimes men with gonorrhea get painful or swollen testicles.

In women, the symptoms of gonorrhea are often mild, but most women who are infected have no symptoms. Even when a woman has symptoms, they can be so non-specific as to be mistaken for a bladder or vaginal infection. The initial symptoms and signs in women include a painful or burning sensation when urinating, increased vaginal discharge, or vaginal bleeding between periods. Women with gonorrhea are at risk of developing serious complications from the infection, regardless of the presence or severity of symptoms.

Symptoms of rectal infection in both men and women may include discharge, anal itching, soreness, bleeding, or painful bowel movements. Rectal infection also may cause no symptoms. Infections in the throat may cause a sore throat, but usually causes no symptoms.

What are the complications of gonorrhea?

Untreated gonorrhea can cause serious and permanent health problems in both women and men.

In women, gonorrhea is a common cause of pelvic inflammatory disease (PID). About 750,000 women each year in the United States develop PID. The symptoms may be quite mild or can be very severe and can include abdominal pain and fever. PID can lead to internal abscesses (pus-filled “pockets” that are hard to cure) and long-lasting, chronic pelvic pain. PID can damage the fallopian tubes enough to cause infertility or increase the risk of ectopic pregnancy. Ectopic pregnancy is a life-threatening condition in which a fertilized egg grows outside the uterus, usually in a fallopian tube.

In men, gonorrhea can cause epididymitis, a painful condition of the ducts attached to the testicles that may lead to infertility if left untreated.

Gonorrhea can spread to the blood or joints. This condition can be life threatening. In addition, people with gonorrhea can more easily contract HIV, the virus that causes AIDS. HIV-infected people with gonorrhea can transmit HIV more easily to someone else than if they did not have gonorrhea.

How does gonorrhea affect a pregnant woman and her baby?

If a pregnant woman has gonorrhea, she may give the infection to her baby as the baby passes through the birth canal during delivery. This can cause blindness, joint infection, or a life-threatening blood infection in the baby. Treatment of gonorrhea as soon as it is detected in pregnant women will reduce the risk of these complications. Pregnant women should consult a health care provider for appropriate examination, testing, and treatment, as necessary.

Alternative Health Care

Natural medicine’s approach to treating all diseases is to look at the whole person and provide treatment that is specific to that person. Through individualized care in classical homeopathy, nutrition, herbal,oriental and Ayurvedic medicines and stress management care, possibly coupled with tradition drugs a person has the best opportunity to heal, because the body is not simply overwhelmed with a chemical antibiotic in hopes of repeatedly and blindly trying to drive the invader out of the body. Overwhelming the delicate systems of the body with chemicals only surpresses the symptoms of the disease and creates deeper pathology. (For more information-Mary Wolken-editor CMA)

‘Vitamin D and diabetes” http://wp.me/p13RKZ-qY

Researchers working at Tufts Medical Center in Boston, under the direction of Professor Anastassios Pittas  reported that 2,000 IU/day of vitamin D, given for 12 weeks, significantly improved pancreatic function in mildly overweight adults with pre-diabetes. Unfortunately, the lead author, Dr. Joanna Mitri, did not comment on the low dose of vitamin D they used, 2,000 IU/day, which only increased vitamin D levels from 24 to 30 ng/ml. Nor, in spite of it being a randomized controlled trial, did the authors make any new clinical recommendations for the people who paid for their study, the citizens of the United States.

They found that pancreatic function increased by 300 in the vitamin D group, but fell by 126 in the placebo group.

Joanna Mitri, Bess Dawson-Hughes, Frank B Hu, and Anastassios G Pittas.  Effects of vitamin D and calcium supplementation on pancreatic b cell function, insulin sensitivity, and glycemia in adults at high risk of diabetes: the Calcium and Vitamin D for Diabetes Mellitus (CaDDM) randomized controlled trial. AJCN. First published ahead of print June 29, 2011 as doi: 10.3945/ajcn.111.011684.

In the end, they studied 22 volunteers in the vitamin D group and 22 in the placebo group. However, to give you an idea of what a feat this study was, how difficult it was to get enough subjects, they started with 911 subjects yet ended up randomizing only 44 into the vitamin D study. They did a parallel calcium study with 45 subjects, which found calcium had no benefit on pancreatic function.

The same senior author, Professor Anastassios Pittas, recently announced the results of a much larger epidemiological study that showed for every 5 ng/mL increase in vitamin D levels, the risk of developing diabetes dropped by 8%.  However, he was quick to warn that such epidemiological studies should not change clinical recommendations, only randomized controlled trials can do that. Then, when he oversees just such a randomized trial, not a word of clinical advice, only the ever-present request for more research money from the citizens of this country.

http://diabetes.webmd.com/news/20110628/study-vitamin-d-may-cut-risk-of-diabetes

Of course the Food and Nutrition Board will say they never said levels greater than 20 ng/ml had no added benefits, only that no good evidence existed for such a benefit at the time they issued their report. Actually, if you exclude the science of epidemiology, that is still a false statement. The point is that history will record that someone was wrong.  Maybe it will be me and the Vitamin D Council’s recommendation, going into its fifth year, that adults should take at least 5,000 IU per day.  Or maybe it will be Professor A. Catharine Ross, of Penn­sylvania State University, the chairwoman of the recent FNB that concluded 600 IU/day is the Recommended Daily Allowance, all adults need.  Looking at the study published today, it is clear that 600 IU/day would not have resulted in a significant improvement in pancreatic function.

I predict that after most of the randomized controlled trials are out – in another ten years – the FNB will meet again and say “whoops,” it should have been 5,000 IU/day all along. However, by then the premature death count will be in the millions.

“Brain tumors up in cell phone users under 20”

 

Cell and cordless phone radiation and cell towers have been implicated as a factor in the demise of the bee and some bird populations now Lennart Hardell, Michael Carlson and Kjell Hansson Mild latest research has found another link between use of mobile and cordless phones and malignant brain tumours.

This new study has been published in the International Journal of Oncology. They concluded that there was a significantly increased risk for glioma from the long-term use of a mobile or cordless phone.

The risk worst for early mega users

The 3 potentially deadly sins for excessive cell users:

  • began using a cell/ cordless phone before you were 20 years old
  • using it constantly – too many hours,
  • carrying it on your body
  • listening with the phone directly on your ear

With first use before the age of 20 – in this group there was almost 5 times the risk after 10 years cordless/cell phone use.

Pooled analysis was performed of two case-control studies on patients with malignant brain tumours diagnosed during 1997-2003 and matched controls alive at the time of study and one case-control study on deceased patients and controls diagnosed during the same time period. Cases and controls or relatives to deceased subjects were interviewed using a structured questionnaire. Replies were obtained for 1,251 (85%) cases and 2,438 (84%) controls.

Highest overall risk was found for the most common type of glioma, astrocytoma. People who had used a wireless phone for more than ten years and begun its use before the age of 20 had increased risks of 95%.

Began your excessive use of the cordless/ cell phone after age 20?

If you began an excessive unprotected use of the mobile phone and your older the increased risk was between 1.3-fold and 1.5-fold if they had used any type of wireless phone for more than ten years.

Please teach our children that mobile/cell phone  use holds a danger to their long-term health and well-being and to use their mobile phones for essential calls only.

Text or use air-tube hands free headsets with a devise attached to protect them from some of the radiation from the phone.  Remember even in off  mode the Electromagnetic Radiation (EMFs.) is reduced, but not eliminated.  All devises with wiring have energy fields that give off EMFs.

Encourage the telecom industry to find ways to protect our health not bury us early from the radiation from mobile devises and cell phone towers.

“Afraid of big bad wolf -diet soda?”

Research results reported at the American Stroke Association International Stroke Conference in Los Angeles

People who drank diet soda daily had a 61 percent increased risk of cardiovascular events compared to those who drank no soda, even when accounting for smoking, physical activity, alcohol consumption and calories consumed per day.”This study suggests that diet soda is not an optimal substitute for sugar-sweetened beverages, and may be associated with a greater risk of stroke,” Hannah Gardener of the University of Miami and her colleagues reported at the conference.

The risk persisted after controlling for metabolic syndrome, peripheral vascular disease, and cardiac disease history.

The researchers looked at more than 2500 people from the multi-ethnic Northern Manhattan Study. Participants were asked to report how much and what kind of soda they drank.

During an average follow-up of 9.3 years, 559 vascular events occurred, including ischemic and hemorrhagic stroke.

The researchers also observed a marginally significant increased risk for vascular events among those who consumed diet soda daily and regular soda once or more a month (adjusted relative risk, 1.74; 95% confidence interval, 0.96 – 3.16).

As reported by Medscape Medical News, previous studies have suggested a link between diet soda consumption and the risk for metabolic syndrome and diabetes.

This is the first time diet drinks have been associated with vascular events.

“Death by worms”

The hookworm, the whipworm and the spiral threadworm cause mortality and death  to one billionpeople across the globe

New parasitic worm discovery could help 1 billion people worldwide.
Scientists have discovered why some people may be protected from harmful parasitic worms naturally while others cannot in what could lead to new therapies for up to one billion people worldwide.
The University of Manchester researchers have, for the first time, identified

Mucin-5AC as a protein that in humans is encoded by the MUC5AC gene to be the key component of the mucus found in the guts of humans and animals is toxic to worms.

Dr Sumaira Hasnain, the lead researcher said “For the first time, we have discovered that a single component of the mucus barrier, the Muc5ac mucin, is essential for worm expulsion.
Learning who is and isn’t susceptible to parasitic worms can lead to new treatments for people with chronic worm infections.

How does Muc5ac mucin effect cells?

  • The abnormal expression of gastric M1/MUC5AC mucin in precancerous lesions and colon cancer.
  • Cigarette smoke when it enters lung tissue induces MUC5AC mucin overproduction via tumor necrosis factor-α-converting enzyme in human airway epithelial (NCI-H292) cells.
  • During inflammation Nitric oxide (NO) is generally increased in airway diseases. This causes NO to increase the secretion of mucin from the goblet cell and submucosal glands.

“These parasitic worms live in the gut, which is protected by a thick layer of mucus,” explained Dr David Thornton, from the University’s Wellcome Trust Center for Cell Matrix Research. “The mucus barrier is not just slime, but a complex mixture of salts, water and large ‘sugar-coated’ proteins called mucins that give mucus its gel-like properties.

By creating more mucous study mice were able to expel this whipworm from the gut. Importantly, the mucus from these mice contained the mucin, Muc5ac. This mucin is rarely present in the gut, but when it is, it alters the physical properties of the mucus gel.
Mice unable to genetically produce Muc5ac were unable to expel the worms, despite having a strong immune response against these parasites. This resulted in long-term infections.

Muc5ac is also essential for the efficient expulsion from the gut like hookworm, and the spiral threadworm. Together, these worms cause mortality and morbidity in up to one billion people across the globe.

“Tai Chi for heart health n office relaxation”

This gentle, graceful movement form packs serious health benefits for all ages that practice Tai chi daily. It has recently been in the news for its help at improving heart heart and for stress reduction.

Many of these exercises can be done sitting at your office desk as well or in a straight back chair at home.

Take 5 minutes  to watch and relax with Tai Chi

“Tai Chi appears to be a safe alternative to low-to-moderate intensity conventional exercise training,” for people with Chronic Heart Failure (CHD)  said Gloria Yeh of Beth Israel Deaconess Medical Center head of the study team . CHD is a debilitating and progressive disease that limits a person’s ability to breathe and move.

People with chronic heart failure may be able to boost their quality of life by doing Tai Chi, the ancient Chinese exercise regimen that teaches each person control of their body, mind and emotional energy through gentle deliberate quiet motions.

Take 5 minutes  to watch and relax with Tai Chi
Archives of Internal Medicine, a journal of the American Medical Association reported that the study was divided into two group sessions of one hour each per week were enough to show significant improvements in mood and confidence.
50 US heart patients were enrolled in Tai Chi program study led by an instructor who guided the class in a series of fluid motions and 50 others who took classroom study in heart education.

Physical responses were similar in both groups, but those who did tai chi showed “significant” improvements in their emotional state response questionaire. The Tai Chi group also reported better “exercise self-efficacy (confidence to perform certain exercise-related activities), with increased daily activity, and related feelings of well-being compared with the education group,” said the study.
“Tai Chi seems to be a safe alternative to low-to-moderate intensity conventional exercise training, It has a good rate of adherence and may provide value in improving daily exercise, quality of life, self-efficacy and mood in frail, deconditioned patients with systolic heart failure,” said Yeh.

Previous studies have suggested Tai Chi, which involves slow, circular movements and balance-shifting exercises, may be helpful to people who suffer from high blood pressure, fibromyalgia and stress. All ages and ability levels can benefit by daily Tai Chi practice.

“Ear traps and continues sound”

Maybe we actually can still hear that person hollering at us or that beautiful melody long after the sound of the voice or instruments are gone.

The some vibrations in the inner ear continue even after a sound has ended researchers have found. In the inner ear seems to serve as the mechanical memory of recent sounds. In addition to contributing to sound perception, auditory memory and understanding.

The inner ear contains a structure called the coiled cochlea, fluid filled structure that contains a “basilar” membrane and associated “hair cells” that serves as the organ of hearing.Sound entering the inner ear causes vibrations of the basilar (bottom ) membrane causing the hair cells to bend and vibrate which in turn convey auditory information to the nervous system.

Some hair cells respond to basilar membrane vibrations by producing forces that increase hearing sensitivity and frequency selectivity through mechanisms that are not completely understood.
Dr. Alfred L. Nuttall from the Oregon Hearing Research Centersays his research shows that there is evidence that some tones produce vibrations that continue even after the end of the stimulus.

Using anesthetized guinea pigs, Dr. Nuttall and colleagues recorded basilar membrane motion and hair cell related potentials in response to various sounds. They observed that after-vibrations were dependent on the magnitude and frequency of the sound stimuli and that even minor hearing loss elicited a profound reduction in after-vibrations.

“The after-vibrations ( like an after shock from an earthquake-editor’s note) appear to be driven by sustained force production in the inner ear – a form of short-term memory of past stimulations,” says Dr. Nuttall.

“The ability to detect brief gaps in an ongoing stimulus is critical for speech recognition; gaps need to be longer than a minimal interval to be perceived,” explains Dr. Nutall. “To the extent that after-vibrations excite the auditory nerve fibers, they may explain part of the difficulty in detecting such gaps.” The study is published by Cell Press in Biophysical Journal.
