Fig. 9: Control experiment: AM depth detection thresholds remain stable across relevant sound levels.

a Adult animals (n = 4) were trained on the AM depth detection task at 45 dB SPL. b Depth detection thresholds across 10 psychometric testing days. Thin lines indicate individual data, and circles with associated error bars indicate mean ± SEM. Once detection thresholds stabilize (i.e., consistent for three consecutive sessions: dotted rectangle), then the sound level was varied from 10-60 dB SPL (c). d Behavioral AM depth detection thresholds across sound level (dB SPL). Open circles indicate individual performance (3 sessions per animal, 4 animals total) and solid circles indicate the group mean (±SEM). A 3-parameter exponential was fit to the data (dotted line). Thresholds asymptote at −15.8 dB (re: 100% AM), which corresponds to 27 dB SPL. Therefore, depth detection thresholds remain consistent for sound levels greater than 27 dB SPL.
