AOBmi (Accessory olfactory bulb, mitral layer) MBA:204 synapses onto MEA (Medial amygdalar nucleus) MBA:403 · Mouse

Monosynaptic rabies tracing started from aromatase-Cre neurons in the medial amygdala labelled mitral/tufted cells in the accessory olfactory bulb. Their dendrites reached AOB glomeruli. About 89% of the labelled cells lay in the anterior AOB. Male mice had roughly ten times more labelled AOB cells per starter neuron than females (1.25 vs 0.13).

AOBmi (Accessory olfactory bulb, mitral layer) MBA:204 projects to MEA (Medial amygdalar nucleus) MBA:403 · Mouse

Fluoro-Gold iontophoresed into the MeA retrogradely labelled nearly all AOB mitral and tufted cells. Labelled cells were split about evenly between the anterior (51%) and posterior (49%) AOB.
