Cotton tip-based olfactory short-term memory test

Mice were presented with cotton swabs laced with the same odorants twice at the indicated time intervals. A different odor was used for each interval time point. The sniffing duration of the cotton swab was recorded for both exposure session. A decrease in investigation during the second exposure of the same odorant is suggestive of olfactory memory of the odorant. A. Data of control mice. B. Data of ERK5 icKO mice.
