A Precise Steroid-Responsive Centrifugal Feedback Projection To The Accessory Olfactory Bulb, Tal Inbar
Masters Theses
The accessory olfactory bulb (AOB) processes pheromonal signals which in turn drive social behaviors. Here we identify a tract of aromatase-expressing (arom+) fibers in the dorsal lateral olfactory tract (dLOT) which terminate in the granule cell layer (GCL) of the AOB. We utilized a retrograde tracer in aromatase reporter animals to delineate the source of these fibers. We show that these input fibers emerge almost exclusively from a contiguous population of arom+ neurons that spans the bed nucleus of the accessory olfactory tract (BAOT) and posterioventral subnucleus of the medial amygdala (MeApv). This population of neurons expresses the estrogen receptor …
