Relationships between anxiety behavior and ultrasonic vocalization. A: Average intensity by time spent in closed arms. B: Average duration by time spent in closed arms. C: Average peak frequency by time spent in closed arms. D: Average bandwidth by time spent in closed arms. Intensity and duration of Pink1−/− calls were associated with anxiety level, with increases in anxiety correlating to decreases in duration and intensity. Calls of WT rats were less strongly associated with anxiety. dB: decibels. Hz: Hertz. Gray shading indicates 95% confidence interval.
