Limbic comes from the Latin origin meaning “border” which suggests that the structures from the limbic system form a border between the upper and lower portions of the brain. The limbic systems main function is to promote survival of the species and to lead to reproduction. The last structure which is considered the crowning achievement of the brains evolution is the cerebral cortex which is the outer and protective layer of the brain. The outer layer, called the cerebrum, is the thin 3mm layer on the upmost layer of the brain. This specific structure has been evolved through convolutions which are folds in the cerebrum. It also divides the brain into right and left cerebral hemispheres. This structure aids in everyday activities such as recognizing objects whether they are near or far, interacting with people who are around us, and solving problems that can surface during
