Neurons are not replaced the way skin epithelium is replaced, where the old
cells die and are sloughed off while new cells grow from deeper layers, but
they are replaced in a piecemeal fashion over time. It's like the
difference between knocking down a house and building a new one and
gradually replacing the carpet, the floorboards, the bricks and so on over
time. Some parts of the neuron such as the synapses are very active and
turn over quickly, while other parts such as the nuclear DNA are less
active and turn over slowly.
