Table 4. CPAP and sham-CPAP groups compared to HC: cerebral regions showing significant task-related activation and deactivation in TPN and DMN regions in 1vs0, 2vs0 and 3vs0 contrasts in active and sham-CPAP patient' groups as compared to HC (MNI coordinates, corrected for multiple comparisons, p = 0.05).
