Figure 7.

Figure 7A illustrates two sound waveforms (y-axis) for AR super lox virgule Y and AR super NesCre during exposure of a sexually receptive female. Figure 7B is a bar graph with standard errors of mean plotting total number (y-axis) of short, flat, upward, and downward (simple group); modulated and complex (complex group); and mixed, one jump, and frequency jump (frequency jump group) syllables (x-axis) for the controls and mutants. Figure 7C is a bar graph with standard errors of mean plotting total duration (y-axis) of short, flat, upward, and downward (simple group); modulated and complex (complex group); and mixed, one jump, and frequency jump (frequency jump group) syllables (x-axis) for control and mutants.

Effect of neural androgen receptor (AR) invalidation on ultrasonic vocalizations (USVs). (A) Representative sound waveform for a control (ARlox/Y, left) and mutant male (ARNesCre, right) in the presence of a sexually receptive female. (B–C) Number (B) and duration (C) of syllable types by category produced during the 4-min recording in the presence of a sexually receptive female. Data are expressed as the means ±SEM of nine males per treatment group, *p<0.05, **p<0.01 compared to control littermates.
