ARH (Arcuate hypothalamic nucleus) synapses onto IB (Interbrain)

Species: Rat
Result: ambiguous
Method: transsynaptic tracer
Sign: unknown
Evidence: Retrograde transneuronal labelling with PRV 152 from the posterior pituitary marked neurons in the arcuate hypothalamic nucleus four days after injection; direct versus multisynaptic connectivity cannot be separated with this method.

Named in the paper: “arcuate hypothalamic nucleus (Arc)” and “posterior pituitary (posterior lobe)”
Made by: an AI model reading the paper (claude-opus-5, extract@0.3.0), 2026-10-10
Checked by: a second AI model (claude-opus-5) agrees, 2026-10-10
“Arc labeling is reported in Figure 4 with transneuronal tracer, so ambiguity fits.”
