PGRNl (Paragigantocellular reticular nucleus, lateral part) synapses onto SPVC (Spinal nucleus of the trigeminal, caudal part)

All claims for this connection
Species
Mouse
Result
present
Method
transsynaptic tracer
Sign
unknown
Evidence
Serotonergic neurons in the medullary lateral paragigantocellular nucleus were among the GFP-positive cells after transneuronal pseudorabies spread from PB-projecting TNC neurons.
Named in the paper
“lateral paragigantocellularis nucleus (LPGi)” and “projection neurons of the trigeminal nucleus caudalis (TNC)”
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

“Fig 3E,3I show 5HT+ LPGi neurons labelled from PB-projecting TNC neurons.”

Status

proposed

Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
