FN (Fastigial nucleus) projects to BLA (Basolateral amygdalar nucleus)

Evidence
The basolateral amygdala showed almost no labelling after fastigial anterograde transsynaptic tracing, and in dual-tracing experiments fastigial-derived tdTomato signals rarely contacted retrogradely EGFP-labelled BLA-projecting neurons, arguing against a mono- or disynaptic fastigial-to-BLA pathway.

Named in the paper
“fastigial nucleus (FN)” and “basolateral amygdala (BLA)”
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-5-5) agrees, 2026-10-09

“Labelling in the amygdala was scarce, and the dual tracing showed separate signals, arguing against an FN-to-BLA pathway.”
