Section 4: Neurons

Not only can the body change neuron networks by adding and removing synapses, but it can also add new neurons. You may have heard that neurons don’t divide into new cells. That’s true. But the body does make new baby neurons every day from pre-neuron cells that can divide. The new neurons will only live if they get included in a neuron network. So they reach out, making new synapses and putting in new receptors to talk to other cells. That should sound familiar – making new synapses and putting in new receptors is also how we learn. That means the same processes involved in learning are also involved in the survival of new neurons every day. As we learn, the neurons survive and our neuron networks continue to grow and be refined.
