In the current paintings, approaches of mobilephone proliferation, mobilephone loss of life, neurogenesis, and gliogenesis within the mouse hippocampus have been studied. The mapping of distribution of hippocampal mitoses and counting in their quantity allowed a extra exact definition of the knowledge about the disposition and age relief of proliferative websites in Ammon's horn and the dentate gyrus within the mouse. hence, the subsequent generalized scheme of improvement and age aid of the germinal zones within the mouse hippocampus has been advised. 1. Ammon's horn a) The ventricular region, from the start of formation of the hippocampus (Ell) till E20 b) The suprafimbrial region, from El6 until eventually P7 2. Dentate gyrus a) The top germinal region ("the anlage of the dentate gyrus" of Stanfield and CowanI979b), from E15 until eventually P3 b) The proliferative sector of the hilus, from P3 until eventually Pl4 c) The subgranular sector, from P3 till grownup age The adduced scheme wishes a few reviews: 1. within the hippocampus (as good as in different formations of the constructing brain), basic precursors of every kind of cells of neuroectodermal starting place are represented by means of cells of the ventricular area. they offer upward thrust to cells of secondary germinal zones within the dentate gyrus and Ammon's horn and are direct precursors of the bulk (if no longer of all) neuronal cells in Ammon's horn, the earliest originating generations of neurons within the dentate gyrus, hippocampal radial glial cells, and, obviously, of a substantial a part of astroblasts and oligodendroblasts in Ammon's horn.

1). One of the most important results obtained during the study of cell proliferation in the developing mouse hippocampus is the discovery of a previously unknown germinal zone, which was termed a suprafimbrial germinal zone of Ammon's horn. This zone lying above the fimbria in the regio inferior of Ammon's horn appears in mice on E16, is maximally pronounced between PI and P3, is considerably reduced on P7, and completely disappears by P14. Until P3, the suprafimbrial zone is connected with the prime germinal zone of the dentate gyrus by a band of actively proliferating cells that lie along the surface of the hippocampus facing the truncus cerebri.

Thus, the above-described subgranular zone, in contrast to other germinal zones of the brain, forms a structural complex with differentiated neurons of the granular layer. In view of this, postnatal neurogenesis in the granular layer is characterized by the absence of cell migration. Granular neurons differentiate in successive rows (outside-in) from cells of the subgranular zone, gradually replacing the latter. Moreover, there is no other structure in the mammalian brain (including the mouse) that can be compared with the granular layer of the dentate gyrus in the duration of neurogenesis.
