Saturation of long-term potentiation in the dorsal cochlear nucleus and its pharmacological reversal in an experimental model of tinnitus.

Animal study

The study used a murine model to investigate the effects of acoustic over-exposure on long-term potentiation (LTP) in the dorsal cochlear nucleus (DCN) and its pharmacological reversal. In vivo administration of magnesium-threonate restored LTP at DCN multisensory synapses and reduced gap detection deficits following acoustic over-exposure, suggesting potential therapeutic intervention for tinnitus.
