Respiratory frequency during 5 min exposure to 5% CO₂. Upper panel wild type (WT) mice at P6, lower panel GAD65-/- animals at P6. Values are mean ± S.E. 1 = significantly different from control, (P between 0.044 and < 0.001). 2 = significantly different from value at 2 and at 3 min (p = 0.023 and 0.025) 3 = significantly different from corresponding min. in GAD65-/- (p = 0.049 at 4 min and 0.017 at 5 min)
