A delayed nonmatching-to-sample task with trial-unique stimuli (DNMS), similar to that used to test object recognition memory in primates, was adapted for use with rats. For each trial of the DNMS task, two stimuli were randomly selected from a pool of 250 small "junk" objects; one member of the pair was designated as the sample. On the first part of a trial, the rat traversed an elevated runway and displaced the sample for food reward. After a 10-s delay, the rat again traversed the runway to… CONTINUE READING
