Mouse Schematic (IMAGE) Cold Spring Harbor Laboratory Caption This schematic illustrates how Li’s team trained mice to associate specific sounds with certain rewards. When the mice heard one sound, water would come out of a spout on their left. But when they heard a sound of another frequency, yummy sugar water would come out on their right.
