GPe (Globus pallidus, external segment) synapses onto STRd (Striatum dorsal region)

Species: Mouse
Result: present
Method: transsynaptic tracer
Sign: unknown
Strength: strong
Evidence: Among basal ganglia and midbrain nuclei, GPe contributed the largest share of rabies-labelled inputs to Kremen1+ SPNs.

Named in the paper: “external segment of the globus pallidus (GPe)” and “Kremen1+ SPNs in dorsal striatum”
Made by: an AI model reading the paper (claude-opus-5-5, extract@0.3.0), 2026-10-10
Checked by: a second AI model (claude-opus-5-5) agrees, 2026-10-10
“The text and Fig. 6B name GPe as the largest basal ganglia/midbrain source.”
Status: proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
