The numbers of neurons born in the human adult hippocampus remains controversial; some studies have reported that in adult humans about 700 new neurons are added in the hippocampus every day, [14] while more recent studies show that adult hippocampal neurogenesis does not exist in humans, or, if it does, it is at undetectable levels.

Elizabeth Gould (born 1962) [1] is an American neuroscientist and the Dorman T. Warren Professor of Psychology at Princeton University. [2] [3] She was an early investigator of adult neurogenesis in the hippocampus, a research area that continues to be controversial.
His research using light and electron microscopy suggested that neurogenesis occurs in the brain of adult mammals, but his findings were rejected by the scientific community at the time in a field that continues to be contentious. [1] [2] Kaplan has recently begun a YouTube channel which offers patient interviews and insights to brain plasticity.
This research revealed some degree of adult neurogenesis in the hippocampus and olfactory bulb of rats, and paved the way for the possibility of neuropoiesis in the adult mammalian brain. Following Altman's work, thymidine-H 3 injections were used to examine the brains of a variety of other species. In the late 1970s Steven Goldman used this ...
However, the SVZ of the ventral telencephalon persists throughout life. The adult SVZ is composed of four distinct layers [5] of variable thickness and cell density as well as cellular composition. Along with the dentate gyrus of the hippocampus, the SVZ is one of two places where neurogenesis has been found to occur in the adult mammalian ...
Gadd45 facilitates hippocampal long-term potentiation and enhances persisting memory for motor performance, aversive conditioning, and spatial navigation. [21] Additionally, DNA methylation has been shown to be important for activity-dependent modulation of adult neurogenesis in the hippocampus, which is mediated by GADD45b.
Peter Eriksson (June 5, 1959 – August 2, 2007) [1] was a Swedish stem cell neuroscientist.. Eriksson was a frequently cited scientist who conducted ground-breaking research on neurogenesis in the hippocampus of the adult human brain.
Adult neurogenesis [ edit ] The olfactory bulb is, along with both the subventricular zone and the subgranular zone of the dentate gyrus of the hippocampus, one of only three structures in the brain observed to undergo continuing neurogenesis in adult mammals.
