Figure 7.

Finger pressing behavior before and after each fMRI scan, including each neurofeedback (NFB) session. A: finger preference in pre- and post-fMRI rapid reaction time tests, as a proportion of the total number of presses. Faded colors indicate each participant’s performance, solid colors indicate means across the group. Within-finger statistical differences from pre- to posttest are shown at ^■P < 0.1 and **P < 0.01. B: confusion between fingers in pre- and post-fMRI rapid reaction time tests. Mis-presses are assigned to a finger pair when the target finger was one of the fingers of the pair but the other finger in the pair was pressed instead. fMRI, functional magnetic resonance imaging.
