The next time you pose a question please consider giving us the source. It is clear that your source was very wrong.
Also consider: when you want to find something in medicine or human biology try a search on NIH. They have wonderful high quality references there, and their general white papers for public consumption are excellent. Prepend "site:NIH" to your google search example:
"site:nih.gov your search term(s) " --- without the quotes, I had to add them to get this to display correctly
There is no scientific evidence to support the idea that the entire brain is replaced every 7 years. While some cells in the brain do have the ability to regenerate, the majority of brain cells are long-lived and can last a lifetime.
Neurons, or nerve cells, do not have the ability to regenerate. However, glial cells, which support and protect neurons, can regenerate under certain circumstances.
The regeneration of brain cells is affected by a variety of factors, including age, genetics, and overall health. Environmental factors, such as diet and exercise, can also play a role in the health and regeneration of brain cells.
In some cases, brain cells can regenerate after injury or disease. However, this process is limited and varies depending on the type and severity of the injury or disease.
The rate of brain cell regeneration varies depending on the type of cell and individual factors. Some cells may regenerate more frequently, while others may not regenerate at all. Overall, the brain is constantly changing and adapting, but the idea of complete replacement every 7 years is not supported by scientific evidence.
