Why are some nerve cells very long?

This means that when axons grow in a long and curved shape, it’s designed that way by the neuron to slow down the action potential of signals in order to optimize the refraction ratio. When neurons aren’t signaling at this ratio, there is a breakdown in information flow efficiency between cells.

What is the lifespan of a nerve cell?

These cells matured into neurons that looked like mouse neurons… but with rat lifespans. They survived for up to 36 months, around twice as long as they normally do in their native mouse brains. “Neurons do not have a fixed lifespan,” says Magrassi. “They may survive forever.
