ABRs as a function of stimulus intensity evoked by tone pips of 1 KHz from the same frog in the reproductive season (a) and non-reproductive season

<p>(<b>b</b>)<b>.</b></p

ABR replicates elicited in response to frequency-specific tone pips at 70 dB SPL from the same frog showing valley-peak waveforms in the reproductive season (a) and non-reproductive season (b).

<p>Rise, plateau and fall (R/P/F) for each frequency are specified on the left-hand side of the figure.</p
