Although it's great to see work being done on sensorineural hearing loss that incorporates damage to the auditory nerve fibers, nt-3 regrowth of neuronal synapses will only work within a 24 hour period. It's been stated by one of the leading researchers in that category whose name is Charles M Liberman.
Those like myself for example, would not make the cut understandably because of the length of time. Unless of course one continuously keeps feeding their brain neurotrophic factors in hope of keeping those damaged neuronal connections alive. Therefore, research needs to be done on how to reestablish a well working in-going neuronal connection between the inner regions of the brain and to the sensory cells inside the cochlea. Stem cells are basically the only option to allow such a thing.
My main question that I would still like to understand is when these sensory neurons retract back into the brain after a broken connection takes place from acoustic trauma/exitotoxicity, where exactly do these neurons fall back to? To the thalamus? To the auditory cortex? These neurons play a big role in passing emotional information along to regions of the brain, so what region do they reside in?
