in the UK 6 million people experience sounds for which there's no external source these people have tinnitus the symptoms of tinnitus are often described as ringing buzzing or whistling sounds that are perceived within the ears or the head however it's not the ear that's responsible instead the causes for tinnitus can be found in the brain the brain is made up of a huge number of active nerve areas which all have different roles sound information is processed via a very specific brain area known as the auditory cortex the auditory cortex is divided up into areas that are responsible for processing different pitches in a similar way in which keys would be arranged on a piano anything which causes us to lose our hearing can have the effect of disrupting this internal keyboard this could be caused by medication loud noises or just the natural aging process due to this disruption there's a reduction of activity in the keyboard areas affected by hearing loss and the nerves that make up the area can start to fire spontaneously this is called neural synchronization or to put it another way if the ear no longer talks to the auditory center then the nerve cells in the auditory Center begin to chatter in an overactive and unregulated way it's this abnormal over activity which causes us to perceive the tinnitus signal over time this abnormal activity becomes permanent modern imaging procedures enable us to see evidence of the abnormal neural synchrony within the auditory part of the brain this abnormal neural synchrony doesn't remain limited to the auditory center brain wave measurements have shown that brain areas regulating attention emotions and stress are also affected the faulty signals in all these areas together allow the tinnitus tone to invade into our consciousness this interaction of brain areas influences the individual level of distress and anxiety experienced by each person as well as the perceived volume and invasiveness of the tinnitus is there a way to reduce and reverse the neural synchrony which is related to tinnitus the neuroscientific answer to this question has been discovered by doctors and scientists of the yulik Research Center near Cologne in Germany it's called acoustic coordinated reset CR neuromodulation treatment with acoustic CR neuromodulation targets the exact cause of the problem this innovative treatment is designed to reduce hyperactivity in the specific regions of the brain that are responsible for generating the tinnitus sound for more on this great offer click the link in the description below this video now you
