BLA (Basolateral amygdalar nucleus) projects to CA3 (Field CA3)

Species: Mouse
Result: present
Method: retrograde tracer
Sign: unknown
Evidence: Retrograde viruses (retroAAV-hSyn-mCherry or AAV11-hSyn-GFP) placed in dorsal CA3 labelled cell bodies in the BLA, showing that BLA neurons send axons to dCA3. The same retrograde strategy (retro-Cre in dCA3 with Cre-dependent GCaMP6m in BLA) was used for photometry of dCA3-projecting BLA neurons.
Source: ERK-dependent hyperexcitability of BLA neurons projecting to dCA3 underlies social dysfunction in a male mouse model of fragile X syndrome
