Named in the paper
“secondary motor cortex (M2)” and “D2-MSNs in the posterior dorsomedial striatum (pDMS)”
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

“M2 supplies 17.13% of D2-MSN inputs.”

Status

proposed
