Figure 2. Habituation and port spatial location influence nose-poking behavior in the presence of non-ethologically relevant odors.

Figure 2.

(A) Line graph representing the mean duration of time mice spent nose-poking across all ports as a function of testing day. In this experiment, 18 mice in total (in several cohorts) were tested for their investigation towards a panel of 5 non-ethologically relevant odors (odor set 1) and then after 2 weeks of break, a different panel of non-ethologically relevant odors (odor set 2). (B) The same data from the same mice, but plotted as a function of port number, with data averaged across all 5 testing days. Nose-poking was greater in the side ports (1 and 5) for both odor sets reflecting a spatial bias.
