Example of a neurofeedback run. Blocks of regulation alternated with blocks of baseline ("counting"). During regulation blocks, the fixed red bar in the upper part of the screen served as a marker of the highest ACC activity as a target. The green moving bar indicated the current level of activity in the ACC, which should be moved toward the red bar. The baseline block was indicated by a static blue bar in the center of the screen.
