It is far more complex than any machine. It is interwoven with approximately 100,000 miles of blood vessels, yet it weighs only 3 lbs. and is composed largely of water. Almost all language issues and reading difficulties can be traced back to it. It is the human brain, an organ whose enigmas seem to multiply the more we learn about it.
Like a vast city, the brain is constantly alive with activity. It contains anywhere between 50 billion and 100 billion neurons, which are nerve cells that produce the short bursts of electricity that allow us to think, feel, and move. Each of these cells has thousands of synapses, which enable them to signal each other.
Most of this activity is centered in the cerebrum, the largest part of the brain. which is divided into several parts which control different functions of the mind and body. These parts of the brain are what enable us to learn about the world around us:
- The occipital lobe allows us to process the information that we receive visually. When we look at words on a page, it is this lobe which permits us to transform the letters into the words that we hear in our head.
- The temporal lobe is what permits us to receive information aurally. It also controls memory, so that we absorb what we learn and are able to retain it for later use.
- The parietal lobe allows us to recognize outside stimuli and react to it. When we touch a rock to see how it feels, recoil from a hot surface, or recognize the voice of someone we love, the parietal lobe is functioning.
- The frontal lobe, which controls reasoning, planning, and problem solving, enables us to use what we learn in order to act in the world. It is also primarily responsible for our emotional reactions.
