More Research on Lateral Inhibition

An interesting paper reveals a little bit more about the relationship between abnormal lateral inhibition and tinnitus. The abstract is a bit opaque:
Tinnitus is likely initiated by a discontinuity in the spontaneous or low-level-stimulus induced neural activity across auditory nerve fibers with different characteristic frequency (CF). This discontinuity may be caused by functional loss of outer hair cells in those regions where inner hair cells are preserved.

The reduced spontaneous activity for nerve fibers with CFs in the hearing loss range may result in a reduction of lateral inhibition at more central levels. This reduced lateral inhibition … Continue Reading

A Comprehensive Summary of the Hypothesized Mechanism Behind Tailor-Made Notched Sound Therapy

Tailor-Made Notched Sound Therapy is an umbrella term that subsumes two types of Notched Sound Therapy:

  • Notched Music Therapy (also referred to as Tailor-Made Notched Sound Therapy by the researchers who discovered it)
  • Notched White Noise Therapy (also referred to as Windowed Sound Therapy by the researchers who discovered it)

Proposed mechanism of Notched Music Therapy:

From this source:

The observed reductions in tinnitus loudness, annoyance and handicapping as well as the reductions in evoked neural activity appear cumulative, indicating a long-term neuroplastic effect. There is evidence in humans that tinnitus is associated with a relative … Continue Reading
