The internal neural problem in the ear and the brain is the cause of tinnitus. In perspective of the neural problem, tinnitus is divided into two parts.
Tinnitus damages hair cells and also it starts to feel like inhibition is lost in the circuit of auditory transmission. And then excitatory cell gets out of control and start firing. Anyone one of us can have tinnitus problem.
The first-time researcher mapped brains signals of a man to find out the constant noise of tinnitus, during undergoing surgery. Their research mainly depends on the cause of tinnitus. Therefore, they put 164 electrodes on the patient’s head. And then compare the activity of the brain with periods when tinnitus was loud and quite.
They found the difference of signals between the activity of the brain in both cases. These changes in the brain use scanning techniques which are less precise than the electrode used in the new study.
The number of models and treatment approaches are made for a certain portion of the auditory cortex. The auditory cortex connects to the hearing frequency either by pointing to the sound of a particular frequency or by pointing physically to the brain of a person. Therefore, maybe these strategies will revise or reconsidered a bit.
These strategies provide higher resolution information about the changes takes place in the brain. The research depending on the cause of tinnitus or bimodal auditory somatosensory stimulation approach delivers sound into the ears. And also alternating it with a weak electrical pulse delivered to the cheek or neck.
Overall the result shows that it was only after receiving the bimodal treatment, that the loudness of phantom sound was less in amount. And the tinnitus-related quality of life improved. Therefore, this research brain is the cause of tinnitus.
The causes are many. But there is good news as the risk of occurrence can be reduced and measures for prevention to avoid this illness can be taken. The latest research offers new insight into the way tinnitus works, may ultimately lead to more effective treatments.
