Top panel, from top to bottom: Run, licking and brain activity during training. Animals had to increase activity in control region 1 (R1, blue) compared to control region 2 (R2, green) to bring a visual cursor to a target to get reward (bottommost trace is activity difference R1-R2). Cyan lines indicate trial starts, pink line indicates success, black line indicates end of a failure trial.
Middle panel: reconstruction of cursor location. Animal had to bring the cursor to position 8 on screen for 300 ms to get reward.
Bottom panel: Video of brain activity, with location of R1 (blue box) and R2 (green box) indicated.
