Hyperexcitability of the Nucleus Accumbens Is Involved in Noise-Induced Hyperacusis

Figure 4

A schematic drawing of the neuronal structures and their projections of the auditory pathway (green lines) and limbic system (red lines) which might be involved in tinnitus and hyperacusis. Please note that the drawing primarily shows the structures and connections most relevant in the context of the proposed mechanism but are not exhaustive. Abbreviations: AC: auditory cortex; vmPFC: ventromedial prefrontal cortex; NAc: nucleus accumbens; AMG: amygdala; IC: inferior colliculi; MGN: medial geniculate nucleus, TRN: thalamic reticular nucleus.
