BNST Plays a Role in Stress and Anxiety (image) Rosalind Franklin University of Medicine and Science Share Print E-Mail Caption The bed nucleus of the stria terminalis (BNST) plays an important role in the regulation of defensive behaviors like fear and anxiety. The image, taken from a female rat brain, reveals a variety of neuronal populations intermingling in the oval nucleus of the of the BNST, including neurons expressing tyrosine phosphatase STEP (blue) and protein kinase C delta (pink). BNST neurons express oxytocin receptors, but their function is not well understood.
