Supplementary Figure 4 : Responses in the main olfactory bulb increase during social interactions but not during nosepoke.

Supplementary Figure 4

(a) Representative image showing histology, fiber placement, and GCaMP6s expression in the olfactory bulb. Scale bar indicates 250 μm. (b) MOB activity was recorded during free social interactions with a male or a female. (c) MOB activity increases during investigative episodes of either males or females. (d-e) Activity during quiet non-investigating epochs (d) has increased power at a frequency matching resting mouse respiratory rate (e, ~2.7 per s, red vertical). (f) Example MOB activity during SIA task, with social and null pokes indicated by blue and red vertical lines respectively. (g-l) Learning curves (g, j), and population GCaMP6 responses aligned to nosepoke (h, k) and male introduction (i, l) for two individuals. c, h-i, k-l show mean ± s.e.m.
