The Brain: "Ringing in the Ears" Actually Goes Much Deeper Than ThatResearch on tinnitus has shown that it's rooted in the very way we process and understand sound. Today tinnitus continues to resist medicine’s best efforts, despite being one of the more common medical disorders. When Schlee compared people who suffer a lot of distress from tinnitus with those who are not much bothered by it, he found that the more distress people felt, the stronger the flow of signals out of the front and back of the brain and into the temporal cortex.
Such complexity may explain why so many different tinnitus treatments work, but only modestly: Each attacks just one part of the tinnitus network. The scientists cannot say for sure how the filtered music soothed their patients, but they speculate that the incoming signals encouraged the tone map to change its structure.
Clearly the auditory cortex is just an early stop on the journey that sound takes from the outside world to our awareness. Steven Cheung and Paul Larson, two doctors at the University of California, San Francisco, set out to reproduce Lowry’s experience. Once signals travel from the ear to the auditory cortex, caudate, and putamen, they eventually make their way to regions of the brain that carry out more sophisticated sound information processing: connecting the sounds with memories, interpreting their meaning, giving them emotional significance. It involves phantom ear sounds or a ringing in the ears that is not caused by any external source. Rather than turn to surgery or medication, these alternative forms of treatment have had promising results for many individuals who have suffered from tinnitus. Some were convinced it was caused by wind that got trapped inside the ear and swirled around endlessly, so they tried to liberate the wind by drilling a hole into the bones around the ear or using a silver tube to suck air out of the ear canal. Surveys show that between 5 and 15 percent of people say they have heard some kind of phantom noise for six months or more; some 1 to 3 percent say tinnitus lowers their quality of life. The vibrations cause nerve hairs in the inner ear to shiver, and that triggers electric signals that travel along the auditory nerve into the brain. Things may start to go awry when toxic drugs, loud noises, or even whiplash cause damage to the nerve hairs in the ears.
Neuroscientists, using increasingly sophisticated brain scans, are finding that changes ripple out across the entire brain. This pattern suggests that the network Schlee discovered is important for the full experience of tinnitus. Christo Pantev of the University of Münster in Germany and his colleagues, for example, have brought some relief to people with tinnitus by rewiring their tone map.
Some neurons in the auditory cortex extend branches down to the brain stem, where they link to a pair of regions called the caudate nucleus and putamen.
The experience left him with partial hearing loss and a high-pitched ringing in his ears that plagued him for 40 years.
They took advantage of the fact that some people with Parkinson’s disease get electrodes surgically implanted in their brain stem to control their symptoms. It is precisely these regions that Schlee and his colleagues noted were behaving strangely in people with tinnitus. After a few seconds, you will notice that the silence has a sort of "sound" of its own, a kind of empty ringing tone. When it is time for bed, consider playing soft music or the sounds ocean waves, the wind, or rain to provide a steady distraction.
Blood flow becomes stronger, which can then add more pressure to the delicate system of hearing.


Tinnitus can force people to withdraw from their social life, make them depressed, and give them insomnia. Some have people listen to certain sounds, others apply magnetic pulses to the brain and even implant electrodes in the brain stem. They also signal back down the line, reaching out to neighboring neurons tuned to nearby frequencies, exciting some and muzzling others. Winfried Schlee of the University of Konstanz in Germany and his colleagues have been making some of the most detailed studies of tinnitus ever, using a method called magnetoencephalography (MEG, for short). Tinnitus, in other words, extends beyond the ear, beyond a hearing-specialized part of the brain, beyond even any single piece of neural real estate. To do so, they edited recordings of music, filtering out the frequencies of the ringing in the ears of their patients, who then listened to the filtered music an average of 12 hours per week. Those regions may be important for processing the signals in several ways, such as categorizing sounds. He argues that it is only when signals reach this large-scale network that we become conscious of sounds, and it is only at this stage that tinnitus starts to cause people real torment. I panicked because I thought I'd gone deaf," he says.Mild tinnitus affects about 10 per cent of the population and in older people can be caused by natural hearing loss. During the day, it may be helpful to wear headphones with the same type of sounds or even radio static on low volume. Each nerve hair is tuned to a particular frequency of sound and excites only certain neurons in the auditory cortex. These feedback controls allow us to sift through incoming sounds for the most important information, so that we are not overwhelmed by meaningless noise.
Bereft of incoming signals, the neurons undergo a peculiar transformation: They start to eavesdrop on their neighbors, firing in response to other frequencies. They take advantage of the fact that every time neurons send each other signals, their electric current creates a tiny magnetic field. Pantev and his collaborators found that their patients’ tinnitus significantly eased. In 2004 Louis Lowry, an ear-nose-and-throat doctor at Thomas Jefferson University in Philadelphia, discovered that the caudate and the putamen play an important role in tinnitus by studying an unusual patient—himself. Schlee’s results suggest that the higher regions of the brain send their own feedback to the auditory cortex, amplifying its false signals. An informed person will tell you that your brain is trying to interpret the lack of stimuli to your hearing and so creates a bit of a filler sound. Ear infections, glue ear or a build up of earwax and conditions such as otosclerosis or Meniere's disease can also be responsible for it.In younger people tinnitus can be triggered by exposure to loud noises that damage the inner ear.
Recent research suggests why: Tinnitus is a lot more complicated than just a ringing in the ears.
MEG allows scientists to detect such changing patterns of activity in the brain 100 times per second.Schlee and his colleagues find widespread differences in the brains of people with tinnitus and those without it.
They also found that the neurons tuned to the tinnitus frequency in the auditory cortex became less active. The patients agreed to undergo several minutes of deep brain stimulation to these regions during surgery as the electrode was being implanted. This ringing sound actually serves a more arcane purpose, covering up a noise we are not meant to hear. What you will hear is a voice that relays an account of events about to happen in the immediate future.


Perhaps the tone of the voice is so horrible that it will drive you mad, or maybe the voice will only predict your death over and over again.
A head injury that involves the ears could also cause a buzzing in the ears that will not go away. The neurons at one end of the auditory cortex are tuned to low frequencies; the farther you go toward the other end, the higher the tuning of the neurons.
As the brain’s feedback controls get rewired, the neurons end up in a self-sustaining loop, producing a constant ringing. A network of regions in the brains of people with tinnitus tend to fire their neurons in sync. Cheung and Larson reported that the tinnitus became much fainter in four of the five patients.
Even in bad cases of tinnitus, people can become unaware of the phantom sound if they are distracted.
This noise is not impossible to hear, and if you are persistent you can effectively "break" the cover-up sound.
Simple solutions such as addressing a circulatory condition or removing ear wax may be the answer as well. The Roman writer Pliny the Elder suggested that earthworms boiled in goose grease be put in the ear. If a rat is trained to recognize sounds at a particular frequency, the corresponding region of the tone map will get bigger. That is why tinnitus often doesn’t go away when people get their auditory nerve surgically cut. Schlee has determined that his tinnitus-stricken subjects have a more synchronized pattern of signals coming out of regions in the front and the back of the brain. It may be that distractions deprive the errant signals from the auditory cortex of the attention they need to cause real distress. The next time you are silent and hear the ringing, shout at the top of your lungs for about half a minute, then be abruptly silent. As time goes on, you will be able to make out this voice under increasingly noisy circumstances, to the point that it can be heard at any time by just concentrating. What’s more, some of the most effective treatments for tinnitus appear to work by altering the behavior of the front of the brain. However, he didn't find it easy."People would try to get my attention and I wouldn't be able to hear them," he says. However, there are home remedies that can assist a person in quieting this bothersome ringing. Counseling, for example, can make people better aware of the sounds they experience by explaining the brain process that may underlie the disorder, so they can consciously reduce their distress.
It is simply a matter of trial and error, finding the best course of action to eliminate that aggravating ringing in the ears.
