Connections of area RT in case VA-r. (A–K) Distribution of labeled cells in the STP, STG, and temporal pole after FB injection into the caudal part of area RT (section G; see also Fig. 1I). Labeled cells were observed in Tpt (A) and in medial belt area MM (C), though none were observed in caudal belt areas CM, CL, or caudal AI (B). A moderate to dense concentration of cells was observed in the ventral portion of the CPB (section C and panel L), rostral AI and the adjacent lateral belt (D and E), caudal R (E, and panel N), and area RM (E, and panel M). The strongest concentration of label was within rostral R (F), particularly in the medial portion (see panels O and P). Cells were located in the belt areas medial and lateral to the injection site, extending into the RPB and STGr (F and G). Cells were found throughout the more rostral portion of RT and RTL (H), and RTp, with some label in the dorsal temporal pole areas TGdd/TGdg, and STGr (sections I, J, K, and panel Q). A sparse concentration of cells was present in the dorsal temporal pole (K). Scale bars = 5 mm in (A–K) and 0.2 mm in (L–Q). For other conventions see Figure 4.
