Autoradiographic and histological evidence of postnatal hippocampal neurogenesis in rats Tập 124 Số 3 - Trang 319-335 - 1965
Joseph Altman, Gopal D. Das
AbstractIn the autoradiograms of young rats injected with thymidine‐H3 many of
the granule cells of the dentate gyrus were found labeled. The number of labeled
cells declined rapidly with increased age at the time of injection. Histological
studies showed the presence in young rats of a large germinal matrix of mitotic
cells in the ependymal and subependymal layers of the third and lateral
ventric... hiện toàn bộ
Mode of cell migration to the superficial layers of fetal monkey neocortex Tập 145 Số 1 - Trang 61-83 - 1972
Pasko Rakić
AbstractGolgi and electronmicroscopic methods were used to define the shapes and
intercellular relationships of cells migrating from their sites of origin near
the ventricular surface across the intermediate zone to the superficial
neocortical layers of the parietooccipital region in the brains of 75‐ to 97‐day
monkey fetuses. After mitotic division in either ventricular or subventricular
zones, t... hiện toàn bộ
Distribution of androgen and estrogen receptor mRNA‐containing cells in the rat brain: An in situ hybridization study Tập 294 Số 1 - Trang 76-95 - 1990
Richard B. Simerly, Larry W. Swanson, C. Chang, Masashi Matsushima
AbstractThe distribution of cells that express mRNA encoding the androgen (AR)
and estrogen (ER) receptors was examined in adult male and female rats by using
in situ hybridization. Specific labeling appeared to be largely, if not
entirely, localized to neurons. AR and ER mRNA‐containing neurons were widely
distributed in the rat brain, with the greatest densities of cells in the
hypothalamus, and... hiện toàn bộ
Equal numbers of neuronal and nonneuronal cells make the human brain an isometrically scaled‐up primate brain Tập 513 Số 5 - Trang 532-541 - 2009
Frederico A. C. Azevedo, Ludmila R.B. Carvalho, Lea T. Grinberg, José Marcelo Farfel, Renata Eloah de Lucena Ferretti‐Rebustini, Renata Elaine Paraízo Leite, Wilson Jacob Filho, Roberto Lent, Suzana Herculano‐Houzel
AbstractThe human brain is often considered to be the most cognitively capable
among mammalian brains and to be much larger than expected for a mammal of our
body size. Although the number of neurons is generally assumed to be a
determinant of computational power, and despite the widespread quotes that the
human brain contains 100 billion neurons and ten times more glial cells, the
absolute number... hiện toàn bộ
An autoradiographic analysis of the differential ascending projections of the dorsal and median raphe nuclei in the rat Tập 179 Số 3 - Trang 641-667 - 1978
Efrain C. Azmitia, Menahem Segal
AbstractThe differential projections from the dorsal raphe and median raphe
nuclei of the midbrain were autoradiographically traced in the rat brain after
3H‐proline micro‐injections. Six ascending fiber tracts were identified, the
dorsal raphe nucleus being the sole source of four tracts and sharing one with
the median raphe nucleus. The tracts can be classified as those lying within the
medial f... hiện toàn bộ
Topography of ganglion cells in human retina Tập 300 Số 1 - Trang 5-25 - 1990
Christine A. Curcio, Kimberly A. Allen
AbstractWe quantified the spatial distribution of presumed ganglion cells and
displaced amacrine cells in unstained whole mounts of six young normal human
retinas whose photoreceptor distributions had previously been characterized.
Cells with large somata compared to their nuclei were considered ganglion cells;
cells with small somata relative to their nuclei were considered displaced
amacrine cel... hiện toàn bộ
Differential expression of orexin receptors 1 and 2 in the rat brain Tập 435 Số 1 - Trang 6-25 - 2001
Jacob Marcus, Carl Aschkenasi, Charlotte E. Lee, Richard M. Chemelli, Clifford B. Saper, Masashi Yanagisawa, Joel K. Elmquist
AbstractOrexins (hypocretins) are neuropeptides synthesized in the central
nervous system exclusively by neurons of the lateral hypothalamus.
Orexin‐containing neurons have widespread projections and have been implicated
in complex physiological functions including feeding behavior, sleep states,
neuroendocrine function, and autonomic control. Two orexin receptors (OX1R and
OX2R) have been identif... hiện toàn bộ
An autoradiographic study of the organization of the efferet connections of the hippocampal formation in the rat Tập 172 Số 1 - Trang 49-84 - 1977
Larry W. Swanson, William Cowan
AbstractThe efferent connections of the hippocampal formation of the rat have
been re‐examined autoradiographically following the injection of small
quantities of 3H‐amino acids (usually 3H‐proline) into different parts of
Ammon's horn and the adjoining structures. The findings indicate quite clearly
that each component of the hippocampal formation has a distinctive pattern of
efferent connections... hiện toàn bộ
