Suppression of intake of a gustatory conditioned stimulus (CS) occurs when paired with either an aversive or an appetitive unconditioned stimulus (US). Toxic substances, such as lithium chloride (LiCl), induce conditioned taste aversions while rewarding stimuli, such as high a concentration of sucrose, reduce intake through a comparison process referred to as anticipatory contrast. Drugs of abuse also suppress CS intake, but it is not known whether they do so via their rewarding or aversive… CONTINUE READING
