Scientists remain divided over whether adult human brains generate new neurons
Researchers continue to debate whether the human brain produces new neurons throughout adulthood, challenging the long-held view that people are born with all the neurons they will ever have. Neuroscientists including Arturo Alvarez-Buylla, Hongjun Song and Gerd Kempermann have produced conflicting findings over decades, with current detection methods relying on indirect genetic markers rather than direct proof.
