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 an...... 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 ventr...... 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

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...... 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 ...... hiện toàn bộ Differential expression of orexin receptors 1 and 2 in the rat brain Tập 435 Số 1 - Trang 6-25 - 2001

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 ...... hiện toàn bộ
