Figure 9.

Modular distribution of retrogradely labeled cell bodies of POR → LA/BLA and POR → ENTm projecting neurons in L2/3 of POR. A, B, Tangential section through flatmounted POR showing nonuniform distribution of somata (false-colored green) of POR → ENTm projecting L2/3 neurons labeled by retrograde tracing with rAAV2-Retro/CAG-Cre in Ai 9 mice (A) overlaid with patchy expression of M2 immunostaining in L1 (B). C, Overlay of A and B shows that cell bodies and basal dendrites are preferentially aligned with M2– interpatches. D, Normalized cell counts (mean ± SEM) of POR → ENTm in M2 quantiles (shades of gray) of POR. The fraction of total cell bodies shows a strong preference for M2– interpatches. E–G, Tangential section through flatmounted POR showing nonuniform distribution of somata (false-colored green) of POR → LA/BLA projecting L2/3 neurons labeled by retrograde tracing with rAAV2-Retro/CAG-Cre in Ai 9 mice (E) overlaid with patchy expression of M2 immunostaining in L1 (F). G, Overlay of E and F shows that cell bodies are preferentially aligned with M2– interpatches. H, Normalized cell counts (mean ± SEM) of POR → LA/BLA in M2 quantiles of POR. The fraction of total cell bodies shows a preference for M2– interpatches.
