Figure 5: Below is a 15-s video of a food-restricted rat. On the bottom of the screen, the dopamine signal from the ventral striatum of that rat scrolls on in real-time with the video. The experimenter's hand reaches in to the cage to give the rat a piece of sugary cereal, and a dopamine transient (shown in green) is triggered. After taking the cereal, the rat turns and holds it in its paws to eat.
