When a neuron is damaged, the glial cells remove the neuron, and work to protect the other neurons.Glial progenitor cells can form into neurons or glial cells, depending on what type was damaged.

In some cases, damaged neurons can regenerate through a process called neurogenesis. This process is more commonly seen in certain parts of the brain, such as the hippocampus, and is influenced by various factors including age, type of injury, and overall health of the individual. However, in many cases, damaged neurons may not regenerate completely, leading to potential long-term functional deficits.
yes From: katanatac- The answer is NO! once you kill a brain cell it is forever gone. The only reason say someone with a brain injury is able to over come this injury is because the brain is made up of so many cells that it can re-route the electrical impulses that it sends to make muscles move,ect...
Yes, to some extent they can grow. Right after a stroke is the best time to retrain or rewire the brain. The longer the time after the harder it gets, but recent research shows that brain cells can be renewed and new synapse developed.
Glial cells protect neurons and remove dead neurons. When there is tissue damage, glial progenator cells can differentiate into the target cell to assist in repair.
The sad truth is that they cannot! You can lose them from head collisions, as you age, and various drugs.

Do ovaries regenerate?
No, ovaries do not regenerate. Unlike some tissues in the body, ovaries do not have the ability to regenerate or regrow once damaged.
What tissue is least likely to regenerate itself?
Nervous tissue, specifically neurons, are least likely to regenerate themselves due to their limited ability to divide and replace damaged cells. Injuries to the brain and spinal cord often result in permanent damage because neurons have a low capacity for regeneration compared to other tissues in the body.
Which cells in your body have the least regenerative power?
Neurons in the brain and spinal cord have limited regenerative power compared to other cell types in the body. Once damaged, neurons do not easily replicate or regenerate, which is why injuries to the central nervous system can often have long-lasting effects.
Why can't a damaged cell in the brain be replaced?
Damaged cells in the brain cannot be replaced because the brain lacks the ability to regenerate cells like other organs in the body. Additionally, the complex network of neurons in the brain makes it difficult for new cells to integrate and function properly. Research is ongoing to find ways to stimulate brain cell regeneration, but it remains a challenging area in neuroscience.
How do basal cells contribute to olfaction?
Basal cells are stem cells in the olfactory epithelium that can regenerate olfactory sensory neurons. They differentiate into new olfactory sensory neurons to replace damaged or dying cells, helping maintain the olfactory sensory system's ability to detect and transmit odor information to the brain.
Can the central nervous system regenerate?
No, that is why when someone breaks their spine they are paralyzed for life, because the neurons can not regenerate.
Do ovaries regenerate?
No, ovaries do not regenerate. Unlike some tissues in the body, ovaries do not have the ability to regenerate or regrow once damaged.
Why do injuries in the skin heal faster than injuries to the brain?
The neurons in the brain and else where do not normally regenerate. Skin cells do regenerate.
What tissue is least likely to regenerate itself?
Nervous tissue, specifically neurons, are least likely to regenerate themselves due to their limited ability to divide and replace damaged cells. Injuries to the brain and spinal cord often result in permanent damage because neurons have a low capacity for regeneration compared to other tissues in the body.
Can undamaged neurons make new connection with damaged neurons?
yes
What type of muscle will not regenerate once its severely damaged?
skeletal
Do the cells of the receptor organ in the inner ear regenerate?
No, the cells of the receptor organ in the inner ear, called hair cells, do not regenerate in adult humans. Once damaged or lost, these cells do not typically regenerate, which can lead to permanent hearing loss. Research is ongoing to find ways to regenerate these cells in the future.
Can neurons be replaced easily?
Neurons cannot be easily replaced because they have limited regenerative capacity compared to other types of cells in the body. In the central nervous system, such as the brain and spinal cord, the ability of neurons to regenerate is restricted, making it difficult to replace damaged or lost neurons. However, in certain parts of the peripheral nervous system, such as nerves outside the brain and spinal cord, some regeneration can occur under certain conditions.
Do buildings regenerate if they get damaged in Roblox?
they will only regenerate if they were scripted to do that. More commonly they will regenerate after a certain time (i.e. 300 seconds (5 minutes)) although there are other ways of doing this!
Could damaged neurons in the CNS multiply and grow back?
no
What types of cells if damaged or injured does not reproduce itself and it lost forever?
Neurons in the central nervous system, such as in the brain and spinal cord, do not typically regenerate themselves if damaged or injured. Once these cells are lost, they are not replaced through cell division, making them more challenging to repair compared to other cell types.
Which cells in your body have the least regenerative power?
Neurons in the brain and spinal cord have limited regenerative power compared to other cell types in the body. Once damaged, neurons do not easily replicate or regenerate, which is why injuries to the central nervous system can often have long-lasting effects.
