"TABLE 2. Distribution of Interneurons in the Rat Hippocampus Sagittal sections (50 micrometers) of the rat hippocampus were probed with antibodies raised against somatostatin, parvalbumin, neuropeptide Y, calbindin, cholecystokinin, and calretinin. The total number of cells expressing each marker in each region is given along with the number of 50-micrometer slices analyzed. The total is further broken down to give the number of cells expressing each marker in each layer of each region of the hippocampus. These data are also given as a percentage of the total number of marker expressing cells in that region. Principal cells in the granule cell layer of the dentate gyrus and stratum pyramidale of CA1 express calbindin, preventing identification of interneurons in these regions, have therefore been omitted."

"The neuromodulatory protein somatostatin (SS) was exclusively expressed in hilar neurons and absent from cells in the molecular layer in both age groups (Fig. 4D)."

"Somatostatin neurons constitute one of the largest chemically defined subgroups of GABA [gamma aminobutyric acid] neurons in the dentate gyrus, and virtually all somatostatin neurons of this region are located within the hilus (Fig. 5A)."

"Fig. 5. Somatostatin-containing neurons in the ventral dentate gyrus of the mouse. (A) Numerous somatostatin-immunoreactive cell bodies are present in the hilus (H), and a labeled axonal plexus is evident in the outer molecular layer (M). Little labeling is found in the granule cell layer (G) except for axons from hilar somatostatin neurons that project through this layer."

"On the other hand, SOM [somatostatin]-LIR [like immunoreactive] neurons showed a quite uneven distribution pattern. In the CA1 region, many SOM [somatostatin]-LIR neurons were seen in the stratum oriens (SO), while they were rarely found in the other layers. In the CA3 region,SOM [somatostatin]-LIR neurons were more widely spread. They were seen not only in the SO but also in the SP [stratum pyramidale], SL [statum lucidum] and SR [stratum radiatum]. In the dentate gyrus, SOM [somatostatin]-LIR neurons were exclusively found in the hilus."

"In these experiments, all the cells of the hippocampus immunoreactive for somatostatin were strongly immunoreactive for mGluR[metabotropic glutamate receptor]lalpha, and likewise the cells immunoreactive for mGluRla were also immunoreactive for somatostatin (Figures 2A and 2B)."

"Our preliminary study also indicated that in the dentate gyrus PV-I [parvalbumin-immunoreactive] perikarya did not contain somatostatin immunoreactivity. However, in the hippocampus, a few PV-I neurons, especially those somewhat faintly immunoreactive, contained somatostatin immunoreactivity, indicating some overlapping of PV-I GABA[gamma amino butyric acid]ergic neurons with those containing somatostatin (our unpublished observations).
