LA- and ZI-projecting CR neurons show partial overlap in the PIL
(A) Representative images showing the overlap of LA-projecting and ZI-projecting CR neurons in the PIL. AAV2/2Retro-hEF1a-DIO-eYFP and AAV2/2Retro-hEF1a-DIO-mCherry were injected into the LA and ZI regions, respectively, and allowed to retrograde back to the PIL region. The eFYP+ neurons indicate LA-projecting CR neurons, the mCherry+ neurons indicate ZI-projecting CR neurons, and the yellow neurons (white arrows) indicate collateral-projecting CR neurons. Scale Bar: 200 μm.
(B) Statistical data of overlap percentage of LA-projecting and ZI-projecting CR neurons in the PIL from two mice. Data are represented as mean.
(C) Graphical representation of LA-projecting and ZI-projecting CR neurons showing partial overlap in the PIL.
