Figure 1. ABR thresholds for click and tone pip stimuli are not altered by maternal experience.

Figure 1

A) Averaged click-evoked auditory brainstem responses (ABRs) (500 presentations per stimulus intensity). All traces are labelled with corresponding absolute stimulus intensity on the y-axis and a black dot denotes the threshold stimulus intensity. ABR peak numbers are labelled with roman numerals. The black horizontal bar on the x-axis denotes the duration of the stimulus. B) ABR thresholds for all stimuli. Dots represent ABR thresholds for individual animals with the middle horizontal bar representing the mean and error bars representing the 95% confidence interval.
