Noradrenergic innervation of pyramidal cells in the rat basolateral amygdala

► NE axons in BLa were identified using norepinephrine transporter (NET) antisera. ► NET+ axons in the BLa also contained dopamine-beta-hydroxylase. ► Only half of NET+ axon terminals formed synapses in the BLa. ► NET+ axon terminals mainly innervated distal dendrites of BLa pyramidal cells.
