BLA parvalbumin-expressing interneurons synapses onto BLA glutamatergic principal neurons

Biocytin-filled boutons of PV basket cells were seen by electron microscopy to form symmetrical synapses on somata and dendrites of BLA neurons. In random sampling, 23 of 57 synapses from 6 cells were on dendrites, the rest on somata or proximal dendrites.
