We found that although control mice and non-tinnitus mice show similar non-tinnitus behavior (Figure 1B), similar fusiform cell spontaneous firing rates (Li et al., 2013), similar levels of KCNQ2/3 channel activity (Li et al., 2013), and similar spike parameters (Supplementary file 1; ‘Materials and methods’), non-tinnitus mice are biophysically distinct from control mice. This evidence concerns the gene KCNQ2 and Tinnitus.
