Tinnitus Latest Research.

Researchers in 2020 have reported that Tinnitus is in the brain. The part of the brain which is responsible for Tinnitus is called the “inferior colliculus”.

Tinnitus is in the brain.

Inferior colliculi.

The inferior colliculi of the midbrain are located just below the visual processing centers known as the superior colliculi. The inferior colliculus is the first place where vertically orienting data from the fusiform cells in the dorsal cochlear nucleus can finally synapse with horizontally orienting data.
Sound location data thus becomes fully integrated by the inferior colliculus.
This part of the brain behaves like volume control, it amplifies noise when signals from the ear are at a low level and turns down activity when sound levels are high.
Damage to the cochlea caused by loud noise triggers higher activity in the hearing part of the brain. There are possibly two stages to Tinnitus. At the secondary stage, Tinnitus becomes more established.

How Tinnitus affects us?

Tinnitus has become a pervasive condition that has caused a lot of people to experience and complain bitterly about its effects. This has led to rigorous research in a number of quarters with considerable progress and efforts worthy of commendation.
One of such is the charity “Action on hearing loss”, which has stated that medications needed to treat the loss of hearing could be ready by 2020 with five drugs in the final stages of clinical testing and a further 13 in the early stages of clinical development.

The National Center for Rehabilitative Auditory Research in the United States is another research organization that has led to impressive results. They have successfully demonstrated that there was a reduction in the loudness of tinnitus in individuals that were treated with Levo® (treating tinnitus while asleep).

Another important research result worthy of mention is the American Tinnitus Association (ATA) funded researches. The Research-specific work package 3: “comparability of scientific and clinical results” showed that there is a complex network in the brain that is responsible for the symptoms caused by tinnitus.

It was observed that this complex network was responsible for attention, emotion, memory, and motion. The researchers are looking to employ the process of elimination by removing each section of the complex network and figure out which is implicated in tinnitus in the hopes of finding a permanent cure to tinnitus.

Wearable sound generator.

Sound generator.

While the cure is still being researched, new ways of managing the condition are being developed as well. The innovation of wearable sound generators that work by emitting soft sounds into the ear in order to mask the ringing sounds of tinnitus has been developed.

There are also smartphone apps such as sensitometric corporation and Tinnitus Balance that work just like sound generators.
Another technique called acoustic neural stimulation is also available in treating severe cases of tinnitus.

The acoustic signal transmitted through the music stimulates changes in the neural circuit of the brain and hence desensitizes the individual to their tinnitus.
With these various ways of managing the condition and newer ones coming out, there is certainly hope for an individual suffering from Tinnitus.
