Humans are social creatures—even the most introverted among us. Nourishing and maintaining healthy relationships with friends and family is an excellent way to stimulate your brain and feel ...
These organisms can represent a model for the genetic analysis of adult neurogenesis and brain regeneration. There has been research that discuss how the study of “damage-responsive progenitor cells” in Drosophila can help to identify regenerative neurogenesis and how to find new ways to increase brain rebuilding.
Neurogenesis occurs very little in adults; it only occurs in the hypothalamus and striatum to a small extent in a process called adult neurogenesis.Environmental enrichment, physical activity and stress (which can stimulate or hinder this process) are key environmental and physiological factors affecting adult neurogenesis.

Endogenous regeneration in the brain is the ability of cells to engage in the repair and regeneration process. While the brain has a limited capacity for regeneration, endogenous neural stem cells, as well as numerous pro-regenerative molecules, can participate in replacing and repairing damaged or diseased neurons and glial cells.
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. [15]
Decreased hippocampal neurogenesis is a characteristic of aging. Environmental enrichment increases neurogenesis in aged rodents by potentiating neuronal differentiation and new cell survival. [57] As a result, subjects exposed to environmental enrichment aged better due to superior ability in retaining their levels of spatial and learning ...
Although the vast majority of neurons in the mammalian brain are formed prenatally, parts of the adult brain (for example, the hippocampus) retain the ability to grow new neurons from neural stem cells, a process known as neurogenesis. [4] Neurotrophins are chemicals that help to stimulate and control neurogenesis.
A company called Tomorrow Biostasis is focusing on human cryopreservation in the hopes it can eventually reverse death. The new Berlin startup has already preserved the bodies of about 10 deceased ...
