3. Figure 1 PFC Axons Overlap with Multiple Projection Neurons in the BLA
(A) (Left) Injections into the PL PFC to label axons and neurons in the BLA. Axes apply to all images. (Right) Injection of AAV-mCherry (red) and CTB-488 (green) in the PL PFC (top left) labels PFC axons (red) and AC neurons (green) in the BLA (bottom middle), with an expanded view (far right). DAPI staining in gray.
(B) Average PFC-evoked AMPAR EPSCs at AC neurons before (green) and after (black) wash-in of NBQX. Arrowhead indicates time of light pulse.
(C) (Left) Dual injections of CTB into the PFC and NAc. (Right) Labeling of AC (green) and AS (purple) neurons in the BLA.
(D) (Left) Dual injections of CTB into the PFC and vHPC. (Right) Labeling of AC (green) and AH (orange) neurons in the BLA.
(E) (Left) Average PFC-evoked AMPAR EPSCs at pairs of AS neurons located in the medial (purple) and lateral (black) BLA. (Right) Summary of EPSC amplitudes at AS neurons located in medial (M) or lateral (L) BLA.
