Postnatal neurogenesis and changing connections
Trends in Neurosciences, 1983Abstract It is generally accepted that the proper function of a nervous system depends on the ordered set of connections between nerve cells. If new neurons are added to a system which is already functioning, then some new connections must be formed and perhaps some old ones removed. In this review, I describe some cases of postnatal neurogenesis and

Postnatal Neurogenesis and Neuronal Regeneration
2004The discovery of neurogenesis in the adult brain has challenged one of the central dogmas of neuroscience. Pioneer reports in rodents seed the ground for a detailed description in birds and reptiles, which was finally confirmed in discrete regions of several mammalian species including humans.

Postnatal Neurogenesis and Dopamine Alterations in Early Psychosis
Recent Patents on CNS Drug Discovery, 2012Schizophrenia is most likely a neurodevelopmental disorder with a characteristic delayed onset of symptoms occurring usually during transition from adolescence to adulthood. Recent studies revealed that both genetic and environmental risk factors for the disease disturb not only embryonic, but also postnatal neurogenesis, possible contributing to ...

The amyloid precursor protein and postnatal neurogenesis/neuroregeneration
Biochemical and Biophysical Research Communications, 2006The amyloid precursor protein (APP) is the source of amyloid-beta (Abeta) peptide, produced via its sequential cleavage beta- and gamma-secretases. Various biophysical forms of Abeta (and the mutations of APP which results in their elevated levels) have been implicated in the etiology and early onset of Alzheimer's disease.

Postnatal Neurogenesis in the Olfactory Bulb
2016This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Neuroscience. Please check back later for the full article. In adult mammals, the olfactory bulb and the hippocampus are the regions in the brain that undergo continuous neurogenesis (production and recruitment of

Nonsynaptic GABAergic Communication and Postnatal Neurogenesis
2008This chapter argues for the view that intercellular γ-aminobutyric acid (GABA)ergic signaling between neural stem cells and neuronal precursors in the subventricular zone (SVZ), also called subependymal zone (1), is critical for controlling postnatal neurogenesis, and that nonsynaptic communication between SVZ cells displays characteristics of that ...

Propofol Administration During Early Postnatal Life Suppresses Hippocampal Neurogenesis
Molecular Neurobiology, 2015Propofol is currently one of the most widely used intravenous anesthetics and has been indicated to induce cognitive dysfunction in adults. Here, we investigated the effects of propofol exposure during early postnatal life on hippocampal neurogenesis.

Delayed postnatal neurogenesis in the cerebral cortex of lizards
Developmental Brain Research, 1988Labelled cells were consistently observed in the medial cortex of the lizard brain after i.p. injections of tritiated thymidine (5 microCi/g b. wt.), 1, 7, 18 or 28 days of survival and posterior autoradiographic evaluation. In 3 groups of specimens (postnatal, young and adult) of the species Podarcis hispanica, after one day of survival, labelled ...

[Postnatal neurogenesis: cells identification and nomenclature].
Morfologiia (Saint Petersburg, Russia), 2014Elaboration of the concept of neural stem cells at the end of the twentieth century resulted in the appearance of the multitude of new terms used for the designation of cells localized in the proliferative zones of the brain. Concurrently, a problem arose concerning the correlation of newly named cells, generally known elements of the nervous tissue ...

Postnatal neurogenesis: from neuroblast migration to neuronal integration.
Reviews in the neurosciences, 2010Ongoing neurogenesis maintains neuronal replacement in a few regions of the mammalian adult brain. One of these regions, the subventricular zone, generates olfactory bulb interneuron precursors that must migrate through the rostral migratory stream to reach the olfactory bulb circuit.
