Brain Cells Can Outlive the Body

Brain cells can live at least twice as long as the organisms in which they reside, according to new research.

The study, published today (Feb. 25) in the journal Proceedings of the National Academy of Sciences, found that mouse neurons, or brain cells, implanted into rats can survive with the rats into old age, twice as long as the life span of the original mice.

The findings are good news for life extension enthusiasts.

“We are slowly but continuously prolonging the life of humans,” said study co-author Dr. Lorenzo Magrassi, a neurosurgeon at the University of Pavia in Italy.

So if the human life span could be stretched to 160 years, “then you are not going to lose your neurons, because your neurons do not have a fixed lifetime.”
