The Truth About Brain Cells: Is Adult Neurogenesis Possible?, Ekene Nnagha, Queen-Helen Egbai, Ahtesham Khizar

Pakistan Journal of Neurological Sciences (PJNS)

Brain cells regeneration involves renewal and repair of neurons and other cells in the brain, with restoration of their functions. Although this phenomenon was thought to end in early childhood, research has proven that adult neurogenesis is highly possible with some limitations. Regeneration of axons in the central nervous system is very slow and more complicated than neuronal regeneration, especially regeneration of peripheral nerves. Brain cell regeneration in the adult brain can help in recovery of damaged brain cells and correct cellular and brain tissue dysfunction that are commonly seen in some neurological disorders such as Stroke, Traumatic Brain Injury …
