Fig. 2.
Average difference DP-grams elicited by 75- (A), 65- (B), and 55-dB SPL (C) primary tones (L1=L2) comparing the immediate post-exposure aftereffects of 2- (open circles) versus 4-h (solid circles) exposures to brevetoxin-3 in the same mice. Note that this subset of mice exhibited DPOAE levels for the four highest test frequencies immediately following the 2-h exposure that were slightly, but non-significantly, lower than their baseline counterparts. A total of n=5 mice (as for Fig. 1, each mouse contributed one DPOAE-level data point per condition that represented the average of its right and left ears) contributed to each plot
