PHAL injections in PRC and NC produce anterograde labeling in BLA. Dark-field photomicrographs showing anterogradely-labeled cortical axons in the BLA as a result of the iontophoretic PHAL injections depicted in Fig. 1. Cortical axons arising in PRC (A–B) or temporal neocortex (C–D) at a low (A, C) or high (B, D) power. Arrows in B and D point to PHAL-labeled axonal varicosities. Scales bars in A and B apply to C and D, respectively. LA, lateral nucleus; BL, basolateral nucleus; STR, striatum; LV, lateral ventricle.
