After reviewing this information, paraphrase the information below. That is, re-write it in your OWN words. One of the important questions raised in behavioral neuroscience asks about the localization of functions within the brain and nervous system. Although this question can be approached with a number of techniques, we can begin by artificially stimulating the area in question and watching for resulting behavior. Interpretation of the results of stimulation research must be done with great caution. Because brain structures are richly connected with other areas of the brain, stimulating one area will also affect other areas to which it is connected. Electrical stimulation of the brain can be applied during neurosurgery. As unpleasant as it may sound to you, most neurosurgery is conducted under local, as opposed to general, anesthesia. The tissues of the brain itself lack receptors for pain. Once the bone and the tissues covering the brain are anesthetized, the surgeon can work on the brain of the conscious patient without causing pain. Why would we put people through such an unpleasant experience? Although brains are similar in many ways from person to person, individual differences frequently do occur. By stimulating an area of the exposed brain with a small amount of electricity and assessing any changes in behavior, the surgeon can identify the area’s functions.
