FIGURE 3

Mid-septotemporal (unless noted otherwise) dentate gyrus and hippocampus in plastic embedded 20 μm-thick horizontal sections. (A) Composite of two focal planes of the dentate gyrus granule cell layer, hilar plexiform layer (hpl), and hilar polymorphic cell layer (hpcl). Cell 3 was cloned into this image from an adjacent field of view. 1, pyramidal (basket) cell; 2, large granule cell; 3, spindle-shaped cell of the hpl; 4; large polygonal neurons; 5, ovoid neurons, the dominant population of the hpcl; 6, small dark triangular cell. (B) CA3. (C) Transition from CA3 to CA1. (D) Composite of two focal planes of the CA1 pyramidal cell layer (CA1pcl), stratum oriens (CA1so), and stratum oriens/alveus border (so/a). (E) Temporal CA1pcl. (F) Proximal subicular cell layer (Scl). (G) Distal Scl. (H) Temporal subiculum. Scale bars: (A) 20 μm; (B–G) 50 μm; (H), 100 μm.
