Tinnitus brain plasticity, tinnitus white noise therapy - How to DIY

Author: admin
The Neurotriage system is designed to detect brain impairments to make sports safer by removing players from harm’s way when impaired. The Texas Biomedical Device Center partners with the Texas Brain Injury and Repair center at UTSW to use advanced MRI imaging to track white matter changes following Targeted Plasticity Therapy. Researchers supported by the National Institutes of Health are launching a clinical trial to test a device that uses nervous system stimuli to rewire parts of the brain, in hopes of significantly reducing or removing tinnitus.
UT Dallas researchers are at the forefront of investigations into brain plasticity and its role in the development of tinnitus and chronic pain, as well as stroke, traumatic brain injury, autism, schizophrenia, Alzheimer's disease and Parkinson's disease.
TMNMT is a music-based training directly targeting the source of tinnitus by reducing the increased firing pattern of specific tinnitus-affected neurons.
As studies have shown, the tailor-made notched music training is suitable for tinnitus frequencies which are stable, tonal and below 8000 Hz.
Before the implementation of the treatment the individual tinnitus frequency needs to be accurately analyzed. While listening to the filtered music the neurons of the individual tinnitus frequency experience no stimulation. Owing to the lifelong plasticity of the brain this suppression of the tinnitus neurons can permanently alter their excitability.
In many cases patients report an intensification in the volume of their tinnitus after the first trials of listening to tailor-made notched music. One possible source of tinnitus is thought to be overly active neurons in the auditory cortex of the brain with little inhibiting influence.


Due to the alignment of neurons according to their frequency in the auditory cortex (tonotopy) the filtering leads to an inhibiting influence on the tinnitus from the frequencies below and above it. Neural correlates of tinnitus are the pathologically excitatory neurons and the expansion of the tonotopic map in the auditory cortex.
Tinnitus is a debilitating condition thought to be caused by the brain generating a signal in areas no longer stimulated by the auditory system.

The interdisciplinary program has a very strong connection with the Department of Bioengineering and includes faculty members from the School of Behavioral and Brain Sciences, the Erik Jonsson School of Engineering and Computer Science, and the School of Natural Sciences and Mathematics.
The core principle is to filter and remove frequencies that are specific for the tinnitus of an individual person from any desired piece of music. This is crucial for the following steps since the training is only effective when the notch is centered precisely to the tinnitus frequency. Online software filters the individual tinnitus frequency from the music causing an audible notch in the sound spectrum of the music. By listening to tailor-made notched music over a long enough period of time the overly excitatory neurons of the tinnitus frequency develop a diminished pattern of firing leading to a decrease in the perceived tinnitus loudness. For a long period of time neural plasticity was only expected during brain development, i.e.
By making use of the plasticity of the brain the firing pattern of the tinnitus neurons can be persistently reduced.


The brain’s natural plasticity can potentially be utilized to treat tinnitus, by stimulating adjacent regions of the brain.
Stimulating the vagus nerve releases chemicals involved in neuroplasticity, so doing so while playing the tones will hopefully train the brain to correlate the various sound frequencies to their normal areas in the auditory cortex. The consistent listening to notched music provokes the brain to re-adjust the firing patterns of the neurons and leads to a new equilibrium. Given the lifelong plasticity of the human brain the expose to such a music-based training, applied over a certain period of time, can decrease the over-excitation of tinnitus-related activity in a sustainable manner and, simultaneously, reduces the perceived tinnitus loudness. However, studies up until now haven’t shown significant variations of their tinnitus after listening to tailor-made notched music. Nowadays we know that the brain preserves its plasticity all through lifetime, continuously adapting to new information and changing environments. Hence, TMNMT represents a music-based approach that aims at the very cause of tinnitus and does not only targets its symptoms.
