Hypothalamic Vasopressinergic Projections Innervate Central Amygdala GABAergic Neurons: Implications for Anxiety and Stress Coping

PVH (Paraventricular hypothalamic nucleus) UBERON:0001930 projects to CEA (central amygdaloid nucleus) UBERON:0002883 · Rat

After iontophoretic Fluoro-Gold injection confined to the central amygdala, some vasopressin-immunoreactive magnocellular neurons in the hypothalamic paraventricular nucleus contained the retrograde tracer.

Fluoro-Gold injected into the central amygdala retrogradely labeled vasopressin-positive magnocellular neurons in the supraoptic nucleus, with tracer in perinuclear lysosome-like granules.
