MEA (medial amygdaloid nucleus) synapses onto PMv (Ventral premammillary nucleus)

Immuno-electron microscopy showed axo-somatic synapses between urocortin 3-labelled boutons and immunogold-labelled nesfatin-1 neurons in the PMv. Confocal microscopy also showed synaptophysin-positive Ucn3 terminals on these neurons. The medial amygdala origin of the Ucn3 fibres is taken from earlier work, not traced here.

Made by an AI model reading the paper (claude-opus-5-5, extract@0.3.0); a second AI model (claude-opus-5-5) disagrees. “The EM shows Ucn3 boutons synapsing on PMv nesfatin-1 neurons, but the medial amygdala as the source of those boutons is only cited from earlier work, not traced here, so the subject region is unsupported.”
