Strange ringing sound in my ear, home remedies for tinnitus treatment - For You

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.
Clearly the auditory cortex is just an early stop on the journey that sound takes from the outside world to our awareness. 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. 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.
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.
The experience left him with partial hearing loss and a high-pitched ringing in his ears that plagued him for 40 years. It is precisely these regions that Schlee and his colleagues noted were behaving strangely in people with tinnitus.


Some have people listen to certain sounds, others apply magnetic pulses to the brain and even implant electrodes in the brain stem. 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. 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. 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.


Recent research suggests why: Tinnitus is a lot more complicated than just a ringing in the ears. As the brain’s feedback controls get rewired, the neurons end up in a self-sustaining loop, producing a constant ringing.
Even in bad cases of tinnitus, people can become unaware of the phantom sound if they are distracted. 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. 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.
