Supplementary Figure 4: Responses in the main olfactory bulb increase during social interactions but not during nosepoke.
From: Hypothalamic control of male aggression-seeking behavior
(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.
