The effects of bilateral dialysis of 0.5 mM muscimol into the NTS on the ventilatory equivalent, the V̇E/V̇O2 ratio, while the rat was breathing air (RA) and 7% CO2 (CO2) during wakefulness (left) and NREM sleep (right) are shown for the experiment performed at 24 °C. Mean +/− SEM values are shown. The line with the * shows that the V̇E/V̇O2 values during 7% CO2 breathing are significantly different during muscimol treatment in both wakefulness and NREM sleep (P< 0.01, repeated measures ANOVA interaction with Treatment). N=5 for awake; N=4 for NREM sleep.
