Problem: In relation to PRG, VRG, and DRG, consider the brainstem regions that control ventilation, identify the correct statement out of the options below. For each incorrect statement, identify it as incorrect and explain why it is wrong.
1. The region of the pons just below the PRG but above the medulla appears to be the most important for stimulating ventilation to occur.
2. Neural integration pathways between the DRG and VRG all originate in the DRG and project out to ipsilateral VRG regions.
3. Incoming sensory input can influence how the brainstem respiratory centers behave, but input from higher brain centers cannot influence DRG & VRG firing patterns-the brainstem is restricted to subconscious regulation
