Noise Exposure Alters Glutamatergic and GABAergic Synaptic Connectivity in the Hippocampus and Its Relevance to Tinnitus

Table 4

Animals with tinnitus and animals without tinnitus exhibited different VGAT labeling in most layers, analyzed with two-way ANOVA followed by Tukey-Kramer post hoc correction for multiple comparisons.
