PVH (Paraventricular hypothalamic nucleus) projects to CEA (central amygdaloid nucleus)

Species: Rat
Result: present
Method: retrograde tracer
Sign: unknown
Evidence: After iontophoretic Fluoro-Gold injection confined to the central amygdala, some vasopressin-immunoreactive magnocellular neurons in the hypothalamic paraventricular nucleus contained the retrograde tracer.
