Figure 2

Composite activation/deactivation maps, showing contrast of 2-back task with 0-back task in each experimental sleep condition. Warm colors (orange to yellow) reflect voxels that are more active during 2-back than the control task, with a threshold of T > 3; Cool colors (blue) reflect relative deactivation during 2-back, T < -3. Slices shown are at -19, -15, -11, -3, +9, +11, +13, +15, +23, +37, +43, and +45 mm.
