Functional Characterization of the Basal Amygdala-Dorsal BNST Pathway during Contextual Fear Conditioning

LA (Lateral amygdalar nucleus) MBA:131 projects to BST (Bed nuclei of the stria terminalis) MBA:351 · Mouse

CTB injected into the oval BNST retrogradely labelled cell bodies in the lateral amygdala.

CEA (Central amygdalar nucleus) MBA:536 projects to BST (Bed nuclei of the stria terminalis) MBA:351 · Mouse

After CTB injection into the oval BNST, retrogradely labelled somata were seen in the central amygdala.

BLAa (Basolateral amygdalar nucleus, anterior part) MBA:303 projects to BST (Bed nuclei of the stria terminalis) MBA:351 · Mouse

CTB injected into the dorsal BNST (covering adBNST and ovBNST), and in a separate experiment into the ovBNST, retrogradely labelled cell bodies in the anterior basal amygdala.

BLAp (Basolateral amygdalar nucleus, posterior part) MBA:311 projects to BST (Bed nuclei of the stria terminalis) MBA:351 · Mouse

Retrograde CTB injections into the dorsal BNST and into the ovBNST labelled neurons in the posterior basal amygdala, with a CTB pattern differing from that in the anterior BA.

BLA (Basolateral amygdalar nucleus) MBA:295 projects to BST (Bed nuclei of the stria terminalis) MBA:351 · Mouse

AAV2-GFP injected into the (posterior) basal amygdala, with expression confined to the BA, labelled axons that travelled via the stria terminalis and reached both the oval and anterodorsal BNST. Synapsin I/PSD-95 puncta colocalized along GFP axons in the ovBNST.
