A new study challenges the belief that the brain stops creating new cells, offering hope for treating cognitive decline and diseases like Alzheimer's.
Man in brain-shaped tree illustration
A white-haired man is shown reading at the base of a tree shaped like a brain, with autumn leaves falling from it, in the October 31 edition of New Scientist. The image symbolizes the traditional belief that neurons in the brain disappear over time.Neurogenesis in the hippocampus
Recent studies have shown that the hippocampus, a part of the brain vital for memory and learning, can create new nerve cells through a process called neurogenesis, even in older adults. This challenges long-held views about the brain's ability to change.Shifting scientific understanding
According to Jamie Ducharme in the article, this discovery has led to a reevaluation of how the brain functions and evolves. Hongjun Song, a neuroscience researcher at the University of Pennsylvania, notes that the focus is now on how neurogenesis can be used, rather than whether it exists.Potential benefits of neurogenesis
Neurogenesis is closely tied to cognitive functions like memory, language, reasoning, learning, and decision-making. Researchers suggest it may help prevent cognitive decline and could play a role in conditions like Alzheimer's, Parkinson's, and depression.Exploring ways to stimulate neurogenesis
Scientists are now looking into methods to boost neurogenesis. According to New Scientist, this could offer new treatment options for these conditions and related diseases.Alaska and political developments
In a separate report, The New York Times discusses a Democratic initiative in Alaska that unexpectedly benefits Donald Trump, while also addressing the high profits of oil companies and the environmental issues they raise.Political shifts in Michigan
Some Republicans from Michigan have announced they will not support Trump in the upcoming election, indicating a potential shift in political alliances and voter behavior.About New Scientist
