Figure 3

(A,B) BA-, MV-, 2HEX-, and 2M2B-evoked difference maps from representative male (A), M07) and female (B), F11) mice. (C) Euclidean distance (ED) between 6 pairwise odor map comparisons for the static maps that are shown in (A and B). (D) Mean ± SEM ED between all 6 odor pairs from all male (cyan) and female (magenta) subjects across 64 frames that correspond to 0–9 sec relative to odorant onset. The yellow stimulus bar indicates the time of odorant presentations and the boxed region of the stimulus bar (t1, time bin 1) notes the frames that were used to generate the difference maps in (A,B) and the corresponding ED comparisons shown in C. (E) Enlargement of the boxed region of the frame-by-frame ED analysis in (D) shows that odor maps are more dissimilar in females than in males by as early as 1 sec into the odorant presentations. (F) Overall mean ± SEM ED between odor representations pooled across 6 odor pairs and 64 frames.
