Two-sample t-test analysis: fMRI activation maps under the 2-back condition between the exercise and control sessions (exercise session > control session) at the level of p<0.001 (uncorrected), Z>2.3, and a cluster size >5 voxels for comparisons using cluster detection.

Red areas indicate greater activation during the 2-back condition in the exercise session relative to the control session. Blue areas indicate greater activation during the 2-back condition in the control session relative to the exercise session.
