Yes, neurons are born, a process called neurogenesis.
Where Are Neurons Born?
According to the provided reference, new neurons originate from specific areas within the brain that are rich in neural stem cells. These areas include:
- The subgranular zone (SGZ) in the hippocampus.
- The subventricular zone (SVZ) around the lateral ventricles.
- The hypothalamus.
These regions serve as neurogenic niches, where neural stem cells proliferate, differentiate, and mature into functional neurons. The new neurons then integrate into existing neural circuits.
Summary Table
| Brain Region | Importance |
|---|---|
| Subgranular Zone (SGZ) | New neurons for the hippocampus, crucial for learning and memory |
| Subventricular Zone (SVZ) | New neurons that migrate to the olfactory bulb |
| Hypothalamus | Involved in regulating essential functions like hunger and circadian rhythms |
