This question I posted yesterday as well, but received no help. There wasn't any info about it in my book, so I'm wonderig if you could help me with it.
Why might scientists want to figure out a way to promote cell division in mature nerve cells?
For a long time, we have been taught that neuron cells do not divide.
However, lately, research seem to indicate that certain neurons that do divide (cycle), die soon after. This event appears to take place before the appearance of other markers of the onset of Alzheimer's disease.
You may want to read up on the following articles, and perhaps search for others to completely understand the issue.

MATTER THAT HAS A DEFINITE IS A SOLID.
Promoting cell division in mature nerve cells, also known as neurogenesis, is a topic of interest for scientists due to its potential implications in various fields of study, including neurobiology, regenerative medicine, and mental health. While promoting cell division in mature nerve cells is a complex area of research, I can explain some of the reasons why scientists might want to explore this avenue.
1. Nervous system repair: The adult nervous system has limited regenerative abilities compared to other tissues in the body. When nerve cells are damaged due to injury, disease, or neurodegenerative disorders, they often struggle to repair and regenerate themselves. By finding a way to stimulate cell division in mature nerve cells, scientists hope to enhance the repair and regeneration process, leading to potential advancements in treating neurological disorders and spinal cord injuries.
2. Neuroplasticity and learning: Neuroplasticity refers to the brain's ability to reorganize itself by forming new connections between nerve cells. It plays a crucial role in learning, memory, and adaptation. Research suggests that neurogenesis in certain regions of the brain may contribute to neuroplasticity. By understanding how to promote cell division in mature nerve cells, scientists may uncover mechanisms that enhance neuroplasticity and potentially improve learning and memory functions.
3. Mental health and neurodegenerative disorders: Neurogenesis has also been linked to mental health disorders such as depression and anxiety, as well as neurodegenerative disorders like Alzheimer's and Parkinson's diseases. Studies have shown that reduced neurogenesis may be associated with the onset and progression of these conditions. By finding ways to stimulate neurogenesis, scientists aim to explore potential therapeutic approaches for these disorders and potentially alleviate symptoms or slow down the degenerative process.
4. Developmental research: Studying neurogenesis in mature nerve cells allows scientists to gain insights into the processes underlying brain development and maturation. By understanding how cell division is regulated in mature nerve cells, researchers can expand their knowledge of neuronal development and unravel the complex mechanisms involved in building and maintaining the brain.
It's important to note that promoting cell division in mature nerve cells is an area of active research, and there is still much to learn before potential applications can be fully realized. However, the exploration of neurogenesis holds promise for future discoveries and advancements in understanding the complexities of the nervous system and its various functions.
