(ResearchGate) Our brains keep making new neurons throughout our lifespan, a quality unique to humans.
A newly released study is the first to show that healthy older people continue to produce new brain cells. Researchers autopsied 28 healthy brains donated by people who had no neuropsychiatric disease or treatment affecting the brain. The fact that neurogenesis – the process by which neurons or nerve cells are generated in the brain – continues as people get older means researchers are better equipped to understand why things can go wrong as we age, like with dementia or Alzheimer’s disease.
We spoke to lead author Maura Boldrini, associate professor of neurobiology at Columbia University, about the work.
