Vocalizations during the social interaction test: USV categories. Poly(I:C) exposure did not affect the number of USVs within categories (a) but changed the acoustic characteristics of high frequency modulated (HFM) sounds (b). Data are presented as a mean ± SEM of the number of a given call type (a) and average duration, bandwidth, and peak frequency (b) of the HFM calls. Symbols: *p < 0.05, **p < 0.01, a significant difference between vehicle- and poly(I:C)-exposed males (planned comparisons).
