What goes on inside my brain?

The brain is a complex, but elegantly created organ. It weighs about 3½ pounds. It is a fatty, watery organ laced with blood vessels and nerve fibers inside a hard shell, the skull. It consumes 60% of the glucose the body produces. As the chemistry in the brain operates, electricity is generated. We call this electricity “brainwaves,” and measure them with electroencephalography (EEG). When you take a pill, this changes the blood chemistry. When we train the brain, the brain waves are changed toward better regulation. In turn, the blood chemistry also changes.
