The Limbic System The brain is a very complicated organ consisting of two halves known as hemispheres. There is a left hemisphere, which controls the right side of the body, and a right hemisphere which controls the left side of the body. Another way that the brain is classified in is lobes. There are four lobes that the brain consists of, the frontal lobe, the parietal lobe, the occipital lobe, and the temporal lobe. Most of the action that happens in the brain that is related to sleep is in the hypothalamus, which is located in the Limbic System next to the temporal lobe. The Limbic System is the part of the brain that works with emotions and motives through a network of neural structures; it consists of the hypothalamus, the pituitary…show more content…
