BLA (basal amygdaloid nucleus) projects to CA1 (Field CA1)

Species: Rat
Result: present
Method: anterograde tracer
Sign: unknown
Evidence: After AAV5-CaMKII-hChR2-EYFP infusion into the BLA, which labelled cell bodies only in the amygdala, EYFP-positive axons (no labelled somata) were seen in the temporal half of the hippocampus, most notably in the stratum lacunosum-moleculare of CA1.

“Virally labelled BLA axons, with no labelled hippocampal somata, were seen in CA1 lacunosum-moleculare in all rats, as described in the histology results and Fig. 1D,E.”
