Neurons were transplanted from mice to rats, and the mice neuron lived twice as long as the mice. The researchers believed that if transplanted into even longer lived animals they'd live even longer potentially indefinitely. Likely same for human. But the loss of respiratory reflex as cause of death in elderly was found in animals, and likely applies to humans too.
That is if vascular and support glia cells for neurons were kept youthful it is likely this would reduce rate of neuron death, and might allow for far longer neuron average lifespan potentially extending into two centuries or more.
That said it is true that for a real solution we do need central nervous system regeneration stem cells.
