Neural presbycusis at ultra-high frequency in aged common marmosets and rhesus monkeys
Figure 2. Effects of age on ABR amplitude at ultra-high frequency in marmosets. (A–F) Scatter plots and corresponding regression lines and regression equations for the relationships between ABR amplitudes (μV) of 36 individual marmosets and age (years) at frequencies of 2 kHz (A; R-squared linear=0.0023, P=0.7789); 4 kHz (B; R-squared linear=0.0722, P=0.1129); 8 kHz (C; R-squared linear=0.0138, P=0.4944); 16 kHz (D; R-squared linear=0.05486, P=0.1691); 22 kHz (E; R-squared linear=0.1138, P=0.0442); and 32 kHz (F; R-squared linear=0.1200, P=0.0385).
