a, Cre recombinase causes irreversible expression of HA-TK from
PRVB177 and LVF2TK, and GFP from PRVB316.
b, Viruses were injected into the PVN (blue) of CRH-Cre mice.
c, The olfactory cortex (above) comprises multiple areas and the
vomeronasal amygdala (below) two areas. See Methods for full names.
d, PRV+ neurons in olfactory areas four days after injection
of PRVB316 (n=24) or PRVB177 (n=6). Error bars indicate SEM.
e–g, Photographs and diagrams of olfactory area (blue)
sections30 (red
rectangles) with neurons immunostained for PRVB316 (e) or PRVB177 (f, g)
(green). Scale bars, 200 μm.
