Figure 2. Brain regions showing significant task-related deactivation in the 0vs3-back contrast in A) 1) CPAP group at baseline AND HC (red); 2) CPAP group post-treatment AND HC (blue; purple indicates overlap between 1 and 2); and in B) sham-CPAP group at baseline AND HC (red); 2) sham-CPAP group post-treatment AND HC (blue; purple indicates overlap between 1 and 2).

Green arrows indicate increased deactivation in the tDMN after CPAP treatment (regions in blue), orange arrows indicate decreased deactivation in the tDMN after sham-CPAP treatment (regions in red) (neurological presentation, p<0.05, FDR corrected for multiple comparisons).
