Anterograde injections in subiculum and presubiculum. Left (1): Images of horizontal Nissl‐stained sections overlaid with an adjacent section containing the center of the fluorescent tracer injection. Scale bar; 1,000 μm. Right (2–4): The projections represented in a dorsoventral series of drawings of horizontal sections through RSC. Scale bar: 1,000 μm. (a) A BDA injection in a P14 animal located in distal half of SUB at intermediate dorsoventral levels of SUB. Labeled fibers were present mainly in layer IV and V–VI in A30 and caudal A29. (b) A BDA injection in a P4 animal located at the border between dorsal PrS and dorsal SUB. Labeled fibers were present mainly in layer I and IV of caudal and rostral A30 and A29. (c) A BDA injection in a P17 animal located in deep layers of PrS at intermediate dorsoventral levels. Labeled fibers were present in layer II and V of RSC.
