Figure 2. Accessory olfactory system detects and responds to predator odors.

Figure 2

(A) Percent dissociated VNs showing calcium transients following perfusion with complex odors. Mean ± SEM of 1586-4315 sampled neurons (n=7-21 expts). (B) Increase in cFos expression in the VNO of freely moving behaving animals following exposure to control and kairomone odors. (C) TrpC2 function is necessary for cFos induction in the posterior AOB (pAOB) following exposure to kairomone odors (see Fig. S2 for cFos response to predator odors in the anterior part of the AOB). n=8-20; lu, VNO lumen; gr, granule cell layer of the AOB; mcl, mitral cell layer of the AOB; gl, glomerular layer of the AOB; d, dorsal; m, medial; bar=100μm. Blue labeling = nuclear stain, yellow labeling = anti-cFos immunoreactivity. **P<0.01; ***P<0.001; ANOVA followed by Tukey-Kramer HSD post-hoc analysis (A). Mean ± SEM. Control odor in B and C is clean dry gauze.
