What is NEUROGENESIS?
What is NEUROGENESIS? Neurogenesis is the process by which new neurons are formed in the brain.
The hippocampus alone has at least 27 different types of neurons, Neocortex Basal ganglia Hypothalamus Amygdala Hippocampus
During embryonic development, the mammalian central nervous system (brain and spinal cord) is derived from the neural tube which contains NSCs or neural stem cells, that will later generate neurons
The rate of neurogenesis and the type of neuron generated (broadly, excitatory or inhibitory) are principally determined by molecular and genetic factors. IMG Source: ACNR
Stem cells can divide indefinitely to produce more stem cells, or differentiate to give rise to more specialised cells, such as neural progenitor cells. Neuron Astrocyte Transient Neural progenitors Neural Stem cells Oligodendrocyte
Stem cells were discovered in parts of the adult brain in the 1990s, and adult neurogenesis is now accepted to be a normal process that occurs in the healthy brain.
