PAG (Periaqueductal gray) functionally connects to BLA (basal amygdaloid nucleus)
All claims for this connection- Species
- Rat
- Result
- present
- Method
- optogenetic circuit mapping
- Sign
- unknown
- Evidence
- Blue-light activation of ChR2-expressing CaMKII neurons in the dPAG of freely foraging rats raised the firing of a subset of BLA units recorded with tetrodes; the authors judge the route likely indirect from latencies and anatomy.
- Measurements
- connection probability: 0.1, n = 320

- Named in the paper
- “dorsal periaqueductal gray (dPAG)” and “basolateral amygdala (BLA)”
- 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
“dPAG optogenetic stimulation raised firing in about 10% of 320 and 23 of 85 BLA units in rats, and the authors judge the route indirect, though the paper itself also gives 34 and 22 for these counts.”
- Status
proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
