Mu opioid receptor localization in the basolateral amygdala: An ultrastructural analysis

Highlights • MOR-ir was seen in the Golgi apparatus of pyramidal neurons (PNs) and interneurons. • Many dendritic shafts and spines were MOR+. • Diffuse MOR-ir was seen in the perikarya and dendritic shafts of some interneurons. • MOR+ axon terminals forming asymmetrical synapses mainly contacted sp...

Description
Summary:Highlights • MOR-ir was seen in the Golgi apparatus of pyramidal neurons (PNs) and interneurons. • Many dendritic shafts and spines were MOR+. • Diffuse MOR-ir was seen in the perikarya and dendritic shafts of some interneurons. • MOR+ axon terminals forming asymmetrical synapses mainly contacted spines. • MOR+ terminals forming symmetrical synapses contacted PN somata and dendrites.
