Rostral to caudal morphology of the rat hippocampus at P14.

<p>Representative example of the 1X sections used from a single rat brain. Coronal images are stained with Nissl and have a periodicity of 400 µm from the rostral-most (Fig. 1A) to the caudal-most section (Fig. 1F) of the hippocampus. The sub-regions, CA1, CA2, CA3, and DG, used for the stereology study are outlined (<i>green, CA1; blue, CA2; red, CA3; yellow, DG</i>). Regional boundaries were determined by cross-referencing with the atlases of Paxinos and Watson (2005) and Ramachandra et al. (2011). Bar = 1000 µm.
