English: A chamber used to train and test pigeons' ability to classify images. It is equipped with a food pellet dispenser, and a touch-sensitive screen upon which the medical image (center) and choice buttons (blue and yellow rectangles) were presented. The bird pecks on the button which it thinks is the correct image class and is rewarded accordingly with food. Note that the birds were fed and watered normally and the reward is simply an added bonus.
