Figure 2.

The average BOLD signal extracted from clusters that demonstrated significantly decreased CVR. The red lines represent the signal from the SL group and the blue lines represent the signal from the HA group; the black lines represent the task reference; the periods when the black lines are absent are resting periods without performing the cued maximum inspiration task. Error bars are plotted on the average signal of each group at each time point, representing cross-subject variance measured in SD.
