Prolonged Oxy exposure decreases pup USV call production. (A) Schematic of the treatment paradigm for maternal Oxy exposure and USV measurements throughout development. (B) Cumulative means number of USV calls (dam, p = 0.009; drug, p = 0.001; dam × drug, p = 0.024). Prolonged Oxy exposure led to decreased number of calls relative to prolonged Veh (p = 0.000126) and relative to in utero Oxy exposure (p = 0.002). (C) Line graph of mean call number at all time points. Thick bars and closed circles depict mean call number, with litter size as a covariate, and open circles depict individual call numbers. Error bars represent standard error.
