This layer is also made up of tightly packed neurons and can also be described as the wrinkly, outermost layer that surrounds the brain (the surface of the brain is not smooth but consist of folded bulges that is called gyri which create deep fissures called sulci). This increases the surface area and also the amount of information that is processed. It is also referred to as the gray matter and is also responsible for higher thought processes including speech and decision making
