Fig. 6 — These are visualized in flat reconstructions available through the portal. a, b Results of retrograde tracer injection in medial prefrontal areas (A32V: area 32 ventral; A32: area 32). c, d Injections in rostral dorsolateral prefrontal areas (A46D: area 46 dorsal); e–h injections in caudal dorsolateral and ventrolateral prefrontal areas (A47L: area 47 lateral; A8aV: area 8a ventral; A45: area 45). Even though long-range connections are a characteristic of all prefrontal areas, the medial and rostral areas (a–d) receive a higher proportion of their afferents from other prefrontal areas, in comparison with caudal areas (e–h).
