The brain receives much input from the eyes, the ears and so on. The brain processes these inputs and sends output to the muscles. The brain doesn't work like a modern computer, which works serially. Instead it works in parallel. In that way, the brain is able to handle a vast amount of inputs, and still send out an appropriate answer.

When the brain receives inputs the neurons adapt immediately. In the neurons relationship to each other, the brain learns, or even better - the brain remembers. Every neuron's synapse has a certain influence on the next neuron. By changing these influences, the brain remembers a certain firing pattern, and therefore there is a better chance that this pattern will emerge again. When two neurons fires at the same time, their mutual synaptic strengthes will reinforce each other. Hence there is a greater chance that exactly these two neurons will fire at the same time again.
