|description  = [[fMRI|Functional magnetic resonance imaging]] of the [[human brain]] during gas challenges. Instead of normal air, the participants inhaled pure [[oxygen]]. Yellow 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 region]]s 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]] [[probability of error|p]] = 0.05, [[false discovery rate]] correction.
