There is evidence that parts of the adult brain still show signs of active Neurogenesis.
- Subventricular Zone: near the lateral ventrical.
- This part aids in olfactory processes (smell and processing of smells)
- Dentate Gyrus (Hippocampus):
- This part aids in memory formation, pattern separation, mood regular, cognitive flexibility
- Striatum (detected, still actively researched):
- Helps in motor coordination and control, habit formation, reward processing
Neurogenesis in the Dentate Gyrus
This is the process of neurogenesis that occurs in the dentate gyrus of the hippocampus.
Type 1 Radial Stem Cells are actually Astrocytes (see Neurons and Neural Cells)
Neurogenesis in the Subventricular Zone
Astrocyte turns into a proliferative precursor which then generates into a neurons. The astrocyte then bundles the neurons and transports them to the olfactory bulb.
The study of this in human brains is still under active research, but there are signs that it occurs.
Neurogenesis in the Striatum
This is still under active research, some saying that the cells come from the [Subventricular Zone](#Neurogenesis in the Subventricular Zone).
