The influence of hypothyroidism on the odor detection ability of male Long-Evans rats was determined using high-precision olfactometry and a go/no-go operant task. Nonparametric signal detection measures of sensitivity and responsitivity, as well as measures of S + response latency, the number of aborted trials, and session time were obtained in daily 200-trial test sessions prior to, during, and after 50 days of maintenance on 0.1% propylthiouracil (PTU). Similar determinations were made in control animals. Neither odor detection nor associated nonsensory performance measures were influenced by hypothyroidism. These results ...

These results suggest that PTU-induced hypothyroidism does not affect the odor detection performance of rats.
