Rats quickly learn to avoid licking at a drinking tube containing an odorant and quinine hydrochloride. After training, the rat responds readily to water but sniffs at but does not lick a tube containing a solution of isoamyl acetate. Learning occurs after only one or two exposures to the combination of odor and tastant. This method can be used to demonstrate odor discrimination, odor memory, and to assess detection of low concentrations of odors.
大鼠很快就能学会避免舔舐装有气味剂和盐酸奎宁的饮水管。训练后,大鼠会欣然饮用清水,但会嗅闻装有乙酸异戊酯溶液的管子却不舔舐。只需一两次接触气味剂和味觉剂的组合,大鼠就能学会。这种方法可用于证明气味辨别、气味记忆,并评估低浓度气味的检测能力。
