FIGURE 7

Photomicrographs of the dentate gyrus in Timm-stained sections from adult rats subjected to experimental febrile seizures 3 months earlier (B,D,F), or from controls (A,C,E). Top: Low-magnification views, to demonstrate similar technical processing of samples. Middle: Suprapyramidal blade of the granule cell layer (GCL) from controls, C), or from experimental animals (D). Bottom: analogous set of photographs from the infrapyramidal blade (E,F). The increased numbers of Timm-stained chains of boutons (arrows) are clearly visible in the sections from the experimental group. In addition to increased fiber number, an almost continuous band of Timm-positive boutons (arrowheads) in the GCL- molecular layer (ML) boundary can be seen in experimental (F), but not in control rats (E). H, hilus. Scale bars = 150 μm in A,B; 25 μm in C–F.
