Conditioned taste aversions: Generalization to taste mixtures

摘要: Rats were trained to take their daily water ration within a 30-min session, during which the number of licks per 10-sec presentation drinking tube could be recorded. During one these sessions, three stimuli (sucrose, NaCl or HCl) was presented, followed by administration cyclophosphamide produce conditioned taste aversion. When tested with mixtures stimulus (CS) other two and also quinine hydrochloride, animals avoided containing CS in proportion its concentration mixture. Although natural preferences aversions for interacted somewhat learned aversions, rats responded presence mixture did not generalize CS. Thus, generalization provides good measure behavioral similarities among gustatory stimuli.
