Humans are capable of generating new neurons only upto the age of 20 or so.
Till then, there are very few neuron stem cells that divide to produce neurons.
Others are all arrested. ie. they cannot undergo cell division.
Beyond the age of 20, there are practically no neuron stem cells. They are all locked.

What phase of the cell cycle is suspect for terminal for neurons and red blood cells that they lose their ability to replicate?
Neurons and red blood cells are typically considered to be in the G0 phase of the cell cycle, which is a quiescent stage where cells exit the active cycle and no longer divide. In this phase, they have differentiated and lost the capacity to replicate. This lack of replication is crucial for their specialized functions, as neurons need to maintain stable connections and red blood cells must efficiently transport oxygen without undergoing division.
How often do nerve cells go through the cell cycle?
Nerve cells, also known as neurons, typically do not go through the cell cycle to divide and reproduce. They are terminally differentiated cells that do not undergo cell division once they have matured. This is why nerve cell damage or loss is often irreversible.
Why don't neurons divide, and what is the reason behind their unique characteristic of limited cell division?
Neurons do not divide because they are post-mitotic cells, meaning they have exited the cell cycle and cannot undergo cell division. This is due to their unique characteristic of limited cell division, which is essential for their specialized functions in transmitting electrical signals in the nervous system.
In which stage of the cell cycle does a cell stay in when it no longer divides?
When a cell no longer divides, it typically enters the G0 phase of the cell cycle. This phase is a quiescent state where the cell is metabolically active but not actively preparing to divide. Cells can remain in G0 for an extended period or may re-enter the cell cycle under certain conditions. Examples of such cells include neurons and muscle cells, which often remain in G0 after differentiation.
Do neurons undergo mitosis during their life cycle?
No, neurons do not undergo mitosis during their life cycle. Once they are fully developed, neurons typically do not divide or replicate like other cells in the body.
Clusters of neurons cell bodies are called?
Clusters of neurons cell bodies are called ganglia in the peripheral nervous system and nuclei in the central nervous system. Ganglia contain the cell bodies of sensory or motor neurons, while nuclei contain cell bodies of interneurons or projection neurons.
What are the cell that forms nervous tissue called?
neurons (which trasmit impulses) and glial cells which provide support and nutrition for the neurons.
What neuron has two cell processes?
Neurons with two processes are classified as bipolar neurons.
Another name for nerve cell?
Nerve cells are called neurons.
What phase of the cell cycle are the brain cells in?
NO, brain cells are no a part of the cell cycle. They have their own cycle called the Mitorfolder. This is a dangerous process. While your brain is going through this cycle, usually at age 40, do not drink. Drinking sends a message to the brain to stop working. You will die during this process if you drink. I hope you die.
