Behavioral performance represented in hit and false alarm (FA) rates (plus and cross signs) for cat C4 before starting reference frequency rotations. The frequencies presented during training were 2 and 0.5 kHz. Each point was calculated over a window of 100 trials. The two lines are linear approximations for hit and FA rates over the last 45 and 20 days respectively. Hit rate is stable (slope=2E-06; R2= 3E-07) at 0.92 throughout 45 days and FA stabilized (slope= -4E-04; R2= 1E-03) at 0.23 over the final 20 days indicating good frequency discrimination ability.
