FIGURE 9

Retrograde soma label, in the insular and orbital cortices, resulting from cholera-toxin b (CtB, red) and Fast Blue (FB, blue) injections centered in mediodorsal/paraventricular/centromedial thalamic nuclei and nucleus reuniens/rhomboid (see Supplementary Figure S5 for injection sites corresponding to this case). Rostral to the striatum (A,B) and at anterior through to mid-striatal anterior posterior levels (C–F) the dense soma label encapsulates the claustral area where cell label is substantially attenuated (A–F). Thick dashed lines demarcate the border between the orbitofrontal and insular cortices, while the thin dashed lines designate the approximate borders of the claustrum at rostral levels. Ins, insular cortex; LO, lateral orbital cortex; PIR, piriform cortex. Scale bars = 200 μm.
