Representative recordings of single-unit chemoafferent activity in rats reared in 21% O2 (Control) or 60% O2 (Hyperoxia) through P7 (panels A, B) and after 7 d recovery in room air (i.e., P14; panels C, D). These recordings show raw activity under baseline conditions (21% O2/5% CO2) and during 2-min exposures to mild hypoxia (12% O2/5% CO2) and severe hypoxia (0% O2/5% CO2); there was a 10-min recovery period (21% O2/5% CO2) between hypoxic challenges. Note the robust hypoxic response in Hyperoxia rats after 7 d recovery (panel D) compared to the weak hypoxic response at P7 (panel B).
