Neurons (brain cells) know how to grow dendrites, just like your stomach knows how to digest food. Learning grows dendrites. These new dendrites take time to grow; it takes a lot of practice for them to grow. Connections then form between neurons. When two dendrites grow close together, a contact point is formed. A small gap at this point is called the synapse. Messages are sent from one neuron to another as electrical signals travel across the synapse.
When you learn, specific dendrites grow so that specific neurons connect at specific synapses. As you learn synapses change minute by minute. Some are strong, some of these are weak, so weak they don’t send a signal. Learning helps your weak synapses become strong. Practice builds thick double connections, these connections allow signals to travel faster. Faster, stronger connections last a long time, meaning you remember what you learn.
