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.
