CAMK2G and Tinnitus: Surprisingly, in this set of experiments (Fig. 5A), we found average GPIAS responses to not show any improvement in tinnitus-like responses when lowering activity of CaMKII α-hM4Di+ DCN cells that were inhibited during noise-exposure (n = 6 mice; 5.3 ±2.2% post-NE + NaCl; 16.2 ±11.6% post-NE + CNO; F = 0.8, p = 0.404; Fig. 5F).
