Tinnitus Miracle - A harbinger of deafness

Scientists from the University of London King's College found that tinnitus is a symptom of deafness, even when the violations in the hearing as such is not present or planned. The appearance of tinnitus, the work not of the ear and the auditory nerve and brain.

In chronic nature of the sound, squeak, high whistle, hum and other noise, heard a man in the absence of the various external sources, becoming a serious problem. Previously, this disorder is trying to cure the effects on the auditory nerve, but in some cases, this resulted in complete deafness, but the ringing in your ears without any changes remained, suggesting that it is not only in the ear and auditory pathways to the analyzer and in the brain. So why the brain is still necessary to create a phantom noise?

Tinnitus is often accompanied by hearing defects, but not in all cases. Such exceptions just knocked all researchers astray. That's why scientists have suggested that the hearing defects exist, they simply can not be determined by standard methods. It was tested 15 people with chronic tinnitus and 18 without it. Out of all no one complained at the hearing. Everybody listen to the recording gave a very loud high-frequency sounds. At this time, the scientists recorded the brain activity of participants.

As it turned out, those who have had ringing in the ears, with respect to audible sounds by the brain had been shown a feature. Probably due to nerve damage fabric is passed from ear to the brain by the auditory nerve, the nerve impulse was slightly weakened. However, activity in the auditory brain areas were discernible in the two groups. The brain is somehow compensated for the weakness of the incoming signal.

To compensate for the defect of hearing, auditory analyzer neurons in people with tinnitus miracle are excited without external stimulus. The man himself could not help noticing the defect, but the brain knows about it and tries to take at least some measures, such as creating its own "sound". In the future, a phantom sound becomes obsessive and constant, which indicates the increasing problems with the auditory nerve. That is why, as scientists say, a slight ringing in my ears, heard regularly is the reason for seeking medical attention.
