Glial fibrillary acidic protein (GFAP) inimunos-taining as a marker of astrocyte density increased in the oriens layer of the hippocampus of untreated bilateral carotid artery-ocduded rats as compared to sham occluded animals (De la Torre et al. 1998). 

Numerous intemeurons in the hippocampus are labelled with GluR-A and -D probes (Figs. 15 and 17) (Sommer et al., 1990 Monyer et al., 1991 Catania et al., 1995, 1998), and there are some cells (especially in the stratum oriens) which are strong GluR-C expressors (Monyer et al., 1991 Catania et al., 1998). Many putative intemeurons in the oriens, pyramidal and radiatum layers in both the CAl and CA3 sectors strongly express subunits as flop, but not flip, variants (Fig. 15) (Monyer et al., 1991). 

Fig. 1. Schematic drawing of hippocampus and slice preparation. (A) Dorsal view of the ventricular surface of the rat hippocampal formation, exposed by removing the neocortex. The hatched bar represents the approximate orientation for slicing. (B) Drawing of isolated hippocampal slice, cut in a near-saggital plane as shown in (A). SUB subiculum CAl, CAS region of small and large pyramids, respectively, from nomenclature of Lorente de No (1934) AD area dentata, containing the granule cell layer FISS hippocampal fissure, PP perforant path input to the granule cells, which send mossy-fiber axons (MF) that synapse on the apical dendrites of CAS pyramidal cells SR stratum radiatum, which includes the Schaffer collateral axons of the CAS pyramids SO stratum oriens, which also contains fibers afferent to pyramidal neurons. The alveus consists mainly of CAl pyramidal cell axons. (From Dingledine et al, 1980.)...
