Mechanisms of Noise-Induced Tinnitus: Insights from Cellular Studies.

Neuron · 2019

Review: only animals that develop tinnitus show distinct synchronized spontaneous firing in cochlear-nerve-recipient brainstem neurons, separating tinnitus from hearing loss.

ReviewN/A

Stimulus timing-dependent plasticity in dorsal cochlear nucleus is altered in tinnitus.

The Journal of neuroscience : the official journal of the Society for Neuroscience · 2013

In tinnitus animals, the timing rules governing auditory, somatosensory (bimodal) plasticity in the DCN shift toward anti-Hebbian, the mechanistic rationale for timed bimodal therapy.

Increased Synchrony and Bursting of Dorsal Cochlear Nucleus Fusiform Cells Correlate with Tinnitus.

The Journal of neuroscience : the official journal of the Society for Neuroscience · 2016

DCN fusiform cells fire with increased synchrony and bursting specifically in animals with behavioral tinnitus, a phantom-sound code emerging in the brainstem.

Ventral cochlear nucleus bushy cells encode hyperacusis in guinea pigs.

Scientific reports · 2020

A different DCN-region cell type, ventral cochlear nucleus bushy cells, encodes hyperacusis specifically, extending the DCN account beyond tinnitus alone.
