1) During alveolar HYPERventilation, levels of blood CO2 drop while blood O2 is elevated. What reflexive responses will this stimulate from the CPG?
a) Increased DRG and VRG activity in the medulla, stimulating I and E motor neurons.
b) Decreased DRG and VRG activity in the medulla, stimulating I and E motor neurons.
c) Decreased DRG and VRG activity in the medulla, inhibiting I and E motor neurons.
