- After CaMKIIa-ChR2-mCherry expression in the ILSCm, only sparse mCherry-labelled axon fibres were seen in the adjacent PAG (and deep SC layers).

- Named in the paper
- “ILSCm” and “periaqueductal grey (PAG)”
- Made by
- an AI model reading the paper (claude-opus-5-5, extract@0.3.0), 2026-10-09
- Checked by
a second AI model (claude-opus-5-5) agrees, 2026-10-09
“The paper reports only sparse mCherry axon fibres from the ILSCm injection in the PAG and deep SC, which supports a weak projection.”
- Status
proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
