PVH (Paraventricular hypothalamic nucleus) projects to CEA (Central amygdalar nucleus)

Species: Mouse
Result: present
Method: anterograde tracer
Sign: unknown
Evidence: An oxytocin-promoter EGFP virus injected into the paraventricular hypothalamic nucleus labeled cell bodies there and produced clear labeled axonal fibers in the central amygdala, indicating a direct oxytocinergic projection.
