Larger bandwidth and more sensitive hearing in F1 (CBAxC57) mice. (A) Example FRA illustrating the measurement and computation of BF, CF, and bandwidth. (B) Histograms of BF distributions for C57BL/6 (blue) and F1 (CBAxC57) (orange) mouse strains in both L2/3 (left) and L4 (right). (C) Conventions as in (B), but for CF. (D) BF plotted against CF for each neuron in both mouse strains. Each dot represents an individual neuron. |BF–CF| shows the absolute magnitude of difference between BF and CF for each mouse strain. (E) Cumulative distribution functions of bandwidth in C57BL/6 (blue) and F1 (CBAxC57) (orange) mouse strains in both L2/3 (left) and L4 (right). C57BL/6 breakdown of GCaMP6s lines also displayed for Emx-TetO-GC6 (green) and Thy-GC6 (light blue). ** Indicates significance between C57BL/6 and F1 (CBAxC57) at p < 0.01 (Wilcoxon rank sum test). (F) Example calculation of Receptive Field Sum. (G) Cumulative distribution functions of receptive field sum values in C57BL/6 (blue) and F1 (CBAxC57) (orange) mouse strains in both L2/3 (left) and L4 (right). Median and IQR for each distribution: C57L2/3 = 1.00 (0.83), F1L2/3 = 1.00 (0.66), C57L4 = 1.00 (1.18), F1L4 = 1.00 (0.92). (H) Receptive field sum split up by sound level. Sum is taken across rows in (F) and then averaged across all neurons. * and ** Indicates significance between C57BL/6 and F1 (CBAxC57) at p < 0.05 and p < 0.01 respectively (Wilcoxon rank sum test). Further statistical test details are included in Supplementary Table S1.
