PPN (Pedunculopontine nucleus) synapses onto PB (Parabrachial nucleus)
All claims for this connection- Species
- Mouse
- Result
- ambiguous
- Method
- transsynaptic tracer
- Sign
- unknown
- Evidence
- Pedunculopontine tegmental neurons were rarely labelled with the rabies system after PB injections, a negative result the authors ascribe to limited rabies uptake and transfer rather than to lack of connectivity.

- Named in the paper
- “PPTg” and “PB neurons that project to the amygdala”
- Made by
- an AI model reading the paper (claude-opus-5, extract@0.3.0), 2026-10-09
- Checked by
a second AI model (claude-opus-5) agrees, 2026-10-09
“Text states PPTg was rarely labelled with rabies and ascribes this to a vector limitation.”
- Status
proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
