Brainwaves are electrical readings that reflect brain activity. These electrical impulses can vary in speed and are measured in cycles per second, or hertz (Hz). You can detect a person’s mental state and measure the electrical activity in specific brain areas related to a particular brain function while looking at the rainwave activity. You can think about them as the ripples you can see on the water surface after throwing stones (1). There is always a presence of each brainwave in different parts of the brain, but some will be more pronounced than others depending on whether that person is mentally engaged or sleeping. The amount of a specific wave in a particular region of the brain might indicate a learning disability or even a
neurological injury, which we are exploring in this article.
