ResumoPublisher Summary This chapter discusses the split brain technique that is a significant tool for the study of higher brain function. Myers' technique for the surgical division of the commissures in the cat is readily applicable to primates. It has seen modification in details over the years and special instruments have been devised. A complete section of all forebrain commissures plus the division of the optic chiasm in one operation generally takes from two to three hours, during which time full anesthesia is required. Deep anesthesia is particularly important, while the skin and skull are being opened and again at the close of the operation. Cats may be adequately anesthetized with pentobarbital sodium (Nembutal) using standard methods. More precisely regulated anesthesia is obtained with intravenous injection of the short-acting barbiturate thiopental. With barbiturates, it is recommended to administer an analgesic, such as pethidine, but care must be exercised to avoid respiratory depression.
