The claims behind it

clm-b3swavt7qcpresentretrograde tracerproposed

A retrograde AAV driving mCherry under a CaMKIIa promoter was placed in the BLA and labelled mCherry-positive cells in ventral CA1, showing that excitatory vCA1 neurons send axons to the BLA; a subset of these labelled cells co-expressed c-Fos after unconditioned-stimulus retrieval of remote fear memory.

clm-wp2x6ehnm4presentanterograde tracerproposed

After injecting a CaMKIIa-GCaMP6s virus into ventral CA1, labelled glutamatergic axon terminals were found in the BLA, where an optical fibre recorded their calcium signals, confirming an anterogradely traced vCA1-to-BLA pathway.
