Key Clinical Takeaways (Answer-First)
- Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter governing the central auditory cortex.
- Loss of central GABAergic inhibition causes hyperactive spontaneous firing that manifests as phantom auditory noise.
- Supplemental GABA supports central inhibitory tone, dampening acoustic sensory distress.
- Neurozen provides 100 mg of pharmaceutical-grade biofermented GABA per serving.

The Neurobiology of Central Auditory Inhibition
In healthy hearing, the auditory brainstem and cortex maintain a precise balance between excitatory neurotransmission (glutamate) and inhibitory neurotransmission (GABA). GABA acts as an acoustic volume control, filtering out benign background electrical signals before they reach conscious auditory perception.
What Happens When GABAergic Tone Weakens
Research published in hearing science demonstrates that noise exposure, aging, and vascular stress reduce GABA receptor density along the dorsal cochlear nucleus. Without sufficient inhibitory braking, central auditory neurons fire uncontrollably, creating spontaneous phantom sound loops (Brozoski et al. 2007).
Human Clinical Evidence & Auditory Habituation
Studies evaluating GABAergic cofactors show that restoring central inhibitory balance enhances auditory sensory gating. Patients report that persistent ringing becomes less intrusive, allowing the brain to habituate and push phantom acoustic signals into the background.
Formulation Integration in Neurozen
Neurozen anchors its formula with 100 mg of pure, biofermented GABA, providing direct nutritional support for central auditory calming without inducing pharmaceutical lethargy.
