DR (Dorsal nucleus raphe) projects to BST (Bed nuclei of the stria terminalis)

Species: Mouse
Result: present
Method: anterograde tracer
Sign: unknown
Evidence: Cre-dependent tdTomato AAV injected into the caudal dorsal raphe of ePet1-Cre mice labelled serotonergic terminals in the dorsal BNST bilaterally. Terminal fluorescence was significantly higher in the anterodorsal BNST than in the oval nucleus (n = 3 mice).
Source: Constitutive 5-HT2C receptor knock-out facilitates fear extinction through altered activity of a dorsal raphe-bed nucleus of the stria terminalis pathway
