Summary

Title / Description


Functional magnetic resonance imaging of the human brain during gas challenges. Instead of normal air, the participants inhaled 95% oxygen and 5% carbon dioxide (hypercapnic hyperoxia). Green overlays of regions of significant signal response in 14 children at five successive time periods during the challenges (time scale below images). For location guide, see Image:Brain-MRI-location-guide.png. As shown by images in the top rows, multiple brain regions responded to hyperoxia, but addition of 5% CO2 to the gas mixture altered the timing or greatly reduced most responses (bottom rows), and eliminated all responses after 48 s. Statistical threshold p = 0.05, false discovery rate correction.
