Figure 6 : Odor maps become relatively more discriminable after gonadectomy in males, but relatively less discriminable after gonadectomy in females.

Figure 6

(A) Odor pairs tended to be further apart in Euclidean space (i.e., more dissimilar) in Sham-females than in Sham-males (left panel), and this difference was reversed by gonadectomy (right panel). The mean ± SEM ED between all 6 odor pairs is plotted 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 (CF). (B) The effects of gonadectomy on primary sensory odor representations are plotted as the percent change in ED relative to Sham-control groups. The dashed line indicates no change relative to Sham-controls. Values above and below the dashed line respectively note relative increases and decreases in odor map discriminability. (CF) Pairs of MV- vs EV-evoked difference maps from a representative Sham-male (C, GNX45), Gnx-male (D), GNX37), Sham-female (E), GNX40), and Gnx-female (F), GNX39). (G) Mean ± SEM ED between MV- and EV-evoked maps across all 64 frames for each subject shown in (CF).
