| Abstract |
|---|
Response accuracy and odor sample times on positive (S+) and negative (S) trials were recorded for mice trained on a variety of go, no-go odor detection and discrimination tasks. Odor sample time was relatively stable over extended training on the same task, increased during acquisition of difficult tasks, relatively insensitive to reinforcement magnitude, and, in some cases, provided more information regarding task difficulty and discrimination than did response accuracy. Mice generally sampled longer on S trials in simple odor detection tasks but longer on S+ trials in odor discrimination tasks.
Key words: odor detection, odor discrimination, odor-sampling time, olfactometer
